Hello PCBWAY My name is DenizMy project;As your information, there are various shield models for Arduino uno Boards.These shields reduce the coding time and prevent us from harming economically, but it is very difficult to use with ARDUINO NANO Arduino nano structure is different from ARDUINO UNO structure and this difference prevents us from using shields.pcb i made solves this problemWhen we use arduino nano with pcb, it works just like arduino uno and its dimensions are the same up to its pins, the extra 2 analog inputs are included in it.In this way, we can now use Arduino nano like Arduino uno with its extra features.With the Extra Power Terminal, we can directly connect the connector and provide VIN input to the Arduino.And we can connect different modules as an extraand I increased the number of gnd lines with extra 5v.CARD FEATURES:It is compatible with all Arduino Uno Shield Models.Extra 5v, GND, VIN LinesIncluding Extra Modules.Dimensions One to One Compatible with Arduino UnoWe Can Power The Board With KLEMENSArduino Nano can be removed and installed if you want, so you can use it in different projects.I Would Really Happen If You Accept My ProjectThank you in pcbway Greetings from Turkey

Who Are WeAquaphoton Academy’s undergraduate team began manufacturing submarines in2012 and has been taking part in the annual MATE ROV International Competitionever since.The graduated students then decided to share their passion with aspiring engineers,so they co-founded Aquaphoton Academy to encourage students to engage in thefield of submarines and ROV industry. By sharing their experience and knowledge, themembers of the Academy sought to create a healthy work environment that drives theadvancement of the undergraduates’ technical expertise and urges them to be entrepreneurs in ROV industry.Since then, the team made many achievements in the field of automatic control ofremotely operated vehicles and was the best representative of Alexandria Universityin local and international competitions.About The CompetitionThe MATE competition in an annual event that requires students to think of themselves as “entrepreneurs” and transform their teams into companies that manufacture, market, and sell “products.” In addition to engineering their ROVs, the students are required to prepare technical reports, poster displays, and engineering presentations that are delivered to working professionals who serve as competition judges. Each year a different set of missions is required to be implemented by the participating teams.Aquaphoton Academy Selected Achievements- Best design for our electrical system in the regional MATE ROV 2018 competition.- First place in Underwater Robotics Challenges (UWRC) Egypt 2020.- First place in ROV Egypt 2013 local competition.- First place in ROV Egypt 2014 local competition.- Second place award for underwater missions in the regional MATE ROV 2019 competition.- Third place in ROV Egypt 2019 regional competition in April 2019.- Third place in ROV Egypt 2017 regional competition in April 2017.- Third place in the robotics category at Alexandria's University Science Club competition.Our ProductsAquaphoton Academy latest creation was "Magikarp" an innovative Underwater Remotely Operated Vehicle (ROV) designed to tackle the mission of exploring and excavating underwater archaeological sites.Also Magikarp was a general-purpose ROV designed to meet MATE's 2020 ROV competition.This year we are building a brand new ROV capable of performing extreme maneuvers with the help of a robust electrical system.This year, 2021, our electrical system is composed of 7 main PCBs (+1 for research and development). We are aiming towards a modular design for better portability in the future. The ROV subsystems are as follows:Actuators boardControl Station boardDistribution boardController boardFeedback system boardVision system boardMicro ROV boardThe number of components this year exploded greatly due to different attempts at perfecting our design from last year. Thus, a high-quality SMD board was the best option for us.Currently, we already have an initial design ready, and we are working on finalizing the design by 3D modelling our boards using Eagle and Fusion pipeline.Product HistoryWord To PCBWayPCBWay is our PCB manufacturer of choice. We have already ordered our electrical system PCBs from PCBWay for the last two years; this would be the third one. For the last couple of years we have been really pleased with the quality of your PCBs and would love to keep working with you. We will acknowledge your support in our presentation as well as include it in our technical report and poster. We ask you to sponsor our organization, so we can stay competitive. We would love to keep acknowledging PCBWay's support on our PCBs as always.

Hi guys, my name is Maria and I am a student of electronic engineering at the pedagogical and technological university of Colombia, today I want to present a UCD amplifier, but this time only with N channel mosfets, scalable from 500Wrms to 1250Wrms) This time We are taking advantage of the fact that at least, here in Colombia, the IR2110 is being obtained at a good price and of a very decent quality, and that makes it possible not to go crazy with discrete mosfet drivers, and to use only N-channel mosfets ... And by the way, the amp goes at one!Let's clarify that this is a proof of concept in which many of the desirable characteristics in high power amplifiers have been omitted, such as protections and fuses that will be left to the reader.The main objective of this project is to bring a Class D amplifier closer to those who have no experience with this type of circuitry and one of the most important rules in its design was to simplify it as much as possible and use only common components, low cost and easy to get for everyone.It is also an exercise for the reader, with what to feed this little monster, if they really want to reach its maximum power since it can deliver up to 1200W, an idea could be to use a toroidal transformer since they have a good performance and of course a generous amount of capacitors if you really want to get full powerI have specified IRFP260 as mosfets ... They are not the only possible ones ... For lower powers, much cheaper N-channel mosfets could be used. For example, if the supply voltage will never exceed +/- 20 volts, you could use the IRFZ44, or for 200Wrms over 4/8 ohms, the IRF640 ... Simply, smaller mosfets will heat more.In relation to the heatsink, really, you have to put it ... And the reason is very simple: Although this amplifier has a theoretical efficiency of 97%, at 1250Wrms, that implies 37W of dissipation in the mosfets, so they require a heatsink.However, for example, for 200Wrms output, the power dissipated in the mosfets will be 6W in each one, so a few simple clips could work well. Simply, place an aluminum foil as a heatsink ... And remember that this time, both mosfets have to be isolated from the heatsink with micas and insulating washers ... But the MJE MUST NOT be isolated, because that transistor puts the heatsink to ground to suppress noise emission.The last issue I have left to name is the output inductor issue: It must be able to withstand the peak output current of the amplifier without saturating or burning out. Personally, I use 1mm² of section for every 4 ampere of current (that is, for 8A, I use a wire with 2mm² of section) ... Preferably, instead of using a single wire, use 2 or 3 in parallel whose section added give the required wire section. This will improve the performance of the inductor (I would use, to obtain an equivalent section of 2mm², 3 wires of 0.66mm² section put in parallel)I personally recommend buying the inductors directly since if you do not have experience making them it can become a headache, also this type of amplifier needs that especially the inductor be of the best quality and of a specific frequency since the quality of the sound that we will get from the amplifier, it is for these reasons that I decided to use the inductor 744013119220.I thank the PCBWay company for the support received to carry out this great project

Who are we?CovideX - we are a team of ambitious students from Warsaw University of Technology doing our part in mitigating the overload of healthcare due caused by the COVID-19 pandemic. Our journey started in September 2020 after a group of front-line healthcare workers approach us with a problem to solve - eliminate the need of constant checkups of basic vital signs of patients, who - due to the equipment shortages - could not be provided with complex medical instruments. Such parameters include ECG, hydration, temperature, heart rate, oximetry and respiratory rate. We took on the challenge and started researching possible ways of quickly delivering with a simple, reliable device capable of autonomous monitoring, that would be able to instantly notify about any alarming deviations.What is our idea?The project has been split into two main parts:MonitoringOur research has lead us to the consensus of utilizing a widespread form of a smartwatch. Such an approach enables us to design a robust, long-lasting platform, which does not require any interaction from the user. Its autonomy excellently fits all intended use cases - no matter age, state or technical abilities of the monitored patient. Early tests have proven it possible to achieve up to one week of WiFi-enabled activity on a single charge, creating an opportunity of a whole-hospital-stay charge.NotifyingDue to the fluidity of the current situation, we decided to provide both centralized and personal notifying systems. The centralized system is a currently under-development web app intended to be displayed as a main dashboard for the hospital staff, clearly flagging all patients in need. The personalized approach, on the other hand, is a smartphone app giving the flexibility of being in constant contact - in some way replacing pager functionality.How will the device look like?BandEarly prototypes of the device's cases have already been designed. Although the final outcome is still subject to future changes, we aimed to keep the form clean and minimalist, creating small a non-stigmatizing device that looks nothing like a medical instrument. Monitoring appWhat is our progress so far?We are working quickly and have already reached a stage of designing first prototype boards, hoping to deploy the final device in the next couple of months. Amongst already implemented features are ECG, oximetry and respiratory rate measurement. We seek any help, that would speed up the development - hence we apply for a sponsorship from PCBWay. Our previous encounters with PCBWay have proven nothing but sheer excellence of prototype PCB manufacturing. We would like to cooperate, as we are assured of the quality, promptness and reliability - the virtues we most value.Future plansAs stated, our goal is to implement our solution as fast as possible and, after passing mandatory certifications, release all technical documentation open-source to enable all interested parties to produce the band. Although we are still early in the process, we are positive about current prospects and deeply hope that PCBWay will be interested in partnering in this important initiative <3

In this project, I will be making a controller with which we will be able to control RGB LED strips with our android device over Bluetooth.I will be using an Arduino nano, an HC-05 Bluetooth module, IRFZ44N Mosfet, RGB LED strips, some resistors, capacitors, male/female jumpers, screw terminals, and a PCB.With the mobile app, we will be able to control the lighting colors of the RGB strips.Why did I decide to make this project? I am a student in 11th grade and electronics projects fascinate me. So I was just going through certain YouTube tutorials when suddenly I came across this awesome project and decided to give it a shot.But unfortunately, I do not have the resources and financial condition to make this project. But then I saw that the video was also sponsored by a PCB company.So I thought if I can also get sponsorship then I will also be able to do this project.That is why I came to you.Please support me by sponsoring this video.The maximum budget that I'll require is 70 USD or 5000 INR.Please consider supporting :)

Obstacle-avoiding robots are fairly common and easy to make. Here, you can use this project to add object avoidance functionality to your robot. Or simply use it to start messing around with Python and the hardware peripherals on Raspberry Pi. This system uses IR modules to detect objects, but we will get to the technical side later. So, if you have a Raspberry Pi and want to build something based on hardware using it, just scroll down and have fun. Raspberry Pi robot componentsHow Does the Robot Work?The workings of this robot are really simple. The whole system avoids colliding into obstacles, thanks to its onboard sensors. This robot uses two IR sensor modules, which can detect objects within a range of 5–6cm. This sensor outputs a digital LOW (0V) signal when there is an object within its range, and outputs a digital HIGH (5V) signal otherwise.So how do these IR sensors work? IR stands for infrared, which is a wavelength of light not visible to the human eye. (But it can be seen through our smartphone cameras!) These modules consist of a pair of receiver and transmitter IR LEDs. When an object gets in front of the IR sensor, the surface of the object reflects a part of the IR light back to the receiver. Thus, the receiver then outputs a LOW signal notifying that an object is in front of the sensor.These sensors are wired to the GPIO input pins of the raspberry pi. The pi then using a python script checks whether the GPIO pins connected to the IR sensor modules goes low. If it does go low, then it commands the DC motors to move in the reverse direction first and then turn. Moreover, this robot is initially activated when we push the button on the breadboard, after which the raspberry pi commands the DC motors to move forward via the L293D driver board. You can check out the demo video at the bottom of this page to see how this robot works.Connecting the IR Sensors for the Raspberry Pi RobotRaspberry Pi GPIO pinoutFirst, you need to turn ON your Raspberry Pi after connecting it to the monitor, keyboard, etc. Then we need to check the IR sensor modules. To do this, connect the IR modules to your Raspberry Pi as shown in the following diagram. Power the sensor by providing 5V (+ pin), GND (- pin) from the Raspberry Pi. And connect the B pin on the sensors to Raspberry Pi's GPIO pins 3 and 16. You can check out the Raspberry Pi GPIO pinout as per the pin diagram here. We are using the GPIO.BOARD configuration, which means the pins are numbered based on their normal order on the board (1,2,3, ...). Read the pin configuration on the sensor module and connect correspondingly.Connection diagram — Raspberry Pi IR sensor now i will show u the code of this project . down below here. check it out. Next, you need to copy and paste the following code and save it as a Python file- irtest.py:import RPi.GPIO as GPIO import time GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) GPIO.setup(3, GPIO.IN) #Right sensor connection GPIO.setup(16, GPIO.IN, pull_up_down=GPIO.PUD_UP) #Left sensor connection while True: i=GPIO.input(3) #Reading output of right IR sensor j=GPIO.input(16) #Reading output of left IR sensor if i==0: #Right IR sensor detects an object print "Obstacle detected on Left",i time.sleep(0.1) elif j==0: #Left IR sensor detects an object print "Obstacle detected on Right",j time.sleep(0.1) After saving and running this file, "sudo python irtest.py", you will notice that when you block the sensor with your hand, the following output prints on the screen:IR sensor output from pythonConnecting the Motors With L293DAfter testing the IR sensor modules, you need to connect and test the L293D module and the motors. Power the L293D module by connecting the + and - pins of the board to the 9V battery. Also, connect the "-" of the board to the GND of Raspberry Pi. You can refer to the connection diagram here for completing the connections:Raspberry Pi robot connection diagramNext, you have to provide the inputs to the board. Four output GPIO pins from the Raspberry Pi control the direction of rotation of the two motors. The two terminals of the motors are then connected to the four output terminals of the board. The motors, based on the command from the Raspberry Pi, are powered by the 9V battery. The logic for controlling the motors from the Raspberry Pi is as given below:L293D Raspberry Pi control logicHere, HIGH means a 5V signal or digital 1, and LOW is a 0V signal or digital 0. For example, GPIO.output(5,1) — this command sends a HIGH signal (digital 1) to pin no 5 on the Raspberry Pi. Thus, each motor's direction can be controlled by writing HIGH/LOW signals through two GPIO pins from the Raspberry Pi.Next, you need to wire a push button to the Raspberry Pi as shown in the above connection diagram. This button is used to activate and deactivate the robot. After wiring the robot, attach the wheels. Use double-sided tape to fix the parts together on the robot chassis. You will have a setup that almost looks like this:Raspberry Pi robot assemblyAfter connecting the motors, you need to check them. Use the code below to check the motors and the L293D. Make sure you have powered the driver board (L293D) and given the connections as per the above diagram. After that, copy the code below and save it as a Python file, motor.py, on your Raspberry Pi. Then run it using the command sudo python motor.py. You will notice that both the motors rotate in one direction first, then after a second rotate in the opposite direction. This process repeats until you interrupt it.import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BOARD) GPIO.setup(5,GPIO.OUT) #Left motor input A GPIO.setup(7,GPIO.OUT) #Left motor input B GPIO.setup(11,GPIO.OUT) #Right motor input A GPIO.setup(13,GPIO.OUT) #Right motor input B GPIO.setwarnings(False) while True: print "Rotating both motors in clockwise direction" GPIO.output(5,1) GPIO.output(7,0) GPIO.output(11,1) GPIO.output(13,0) time.sleep(1) #One second delay print "Rotating both motors in anticlockwise direction" GPIO.output(5,0) GPIO.output(7,1) GPIO.output(11,0) GPIO.output(13,1) time.sleep(1) #One second delay Uploading the Code for the Raspberry Pi RobotAfter completing all the hardware setup, you need to download and copy this Python program to your Raspberry Pi. This program is called robot.py, and when executed using the command sudo python robot.py, will bring your robot to life. The robot will begin moving when you press the push button. You'll notice how it avoids objects in front of its sensors and navigates freely.Raspberry Pi robotThis program is very simple. The robot is activated when the user presses the push button, and after that, the robot moves forward and checks whether any obstacles show up in front of it. Whenever your IR modules detect an object within 5cm in front of it, it tells the Raspberry Pi that an object is near it (sending digital LOW signals). Then the Pi sends commands to the motor, making it move in the reverse direction and then turning right or left, and again the robot moves forward by dodging the object. The robot is deactivated when you press the push button again. After copying the code to your Raspberry Pi, you can make it truly wireless by using a smartphone battery bank to power it and a USB Wi-Fi dongle to communicate with it. You can extend the display of ur laptop via VNC server and a LAN cable. Or use SSH to connect remotely to your Pi from the terminal wirelessly. https://learn.adafruit.com/adafruits-raspberry-pi-lesson-6-using-ssh

This is a simple and "cool" Arduino- compatible business card.This is meant for geeky people!Just a bit about it:Mostly through hole components. There's a 1206 LED, but that's easy to solder, with a special hand-solder footprint for it. It's extremely minimal.I've attached a BOM:I'm not sure if it was added correctly, so here is a quick rundown.3 0.1UF ceramic capacitors2 22pF capacitors10K resistor220ohm resistor28 Pin DIP Red(or any other single- color 1206 LED)THT 16MHz crystalAtmega 8, 168, 328- it's compatible with all 3 chips.That's it.(The atmega has to be programmed with Optiboot however)Want to program it?Solder on a 1x6 right angle male header strip to the FTDI port. You can also solder on headers for the Arduino Uno form factor pins. If you want it to be shield compatible, solder on vertical female headers. If you want a lower profile(not really possible with that 328P DIP), you can solder on right angle ones.This board works out-of-box with Arduino IDE, as an UNO, but requires a FTDI adapter, since it does not have a built in USB bridge such as a FTDI chip, the Atmega 8/16u2, CH340, or a CP201x.The PCB is white, there seems to be wasted space on the left, but no! That's where you can write, (or print the silkscreen) for your name, phone number, etc. You can even expose the pads, to make it even prettier. This is also a good gift to give at conventions.Additionally, here's some sample images.I really hope PCBway can help sponsor this project and fabricate this, so it can become a reality.

About UsROACH2 is one of the major missions at KSat, a student group for space projects, with an active team of about 10 students.KSat e.V. (Small Satellite Student Society at the University of Stuttgart) situated in Germany, is a non-profit organization founded in the spring of 2014. The more than 70 members are students of all semesters, most of which are enrolled in Aerospace Engineering.Our goal is to give members the opportunity to realize their own spaceflight projects during their time at university. Furthermore, we aim to pass on the knowledge and enthusiasm for space travel as part of our public relations work and to provide a communication platform between students, interested industry partners, research institutions and the public.Our ProjectROACH2 is our second attempt to build a rover that can drive on surfaces in weightlessness using electroadhesion. With this experiment we want to show that this technology is suitable for the demanding environment of weightlessness and vacuum. Our experiment consists of two components that are built into a sounding rocket. The first component is our autonomous rover with electroadhesive surfaces. The second component is an obstacle course, the inside of the rocket module, which our rover will have to navigate during two minutes of weighlessness. Of course, there are also some sensors and cameras installed, so that the experiment can be better evaluated afterwards. The experiment is part of the REXUS/BEXUS programme, an international student programme in cooperation between the German Aerospace Center (DLR) and the Swedish National Space Administration (SNSA). It is designed as a competition and offers students the opportunity to conduct their own ideas as technical experiments under conditions similar to those in space. The launch, on a sounding rocket up to an altitude of 100km, is currently planned for February 2021.How PCBWay Can Help UsAt the heart of the mission are the electroadhesive pads that generate the attaching force to the surface. They work a lot like one side of a capacitor with the floor as the other side. When a high voltage is applied, a force is generated pulling these two surfaces towards each other. Without this force, our rover would no longer stick to the obstacle course and start simply start floating away. While the principle is simple, these paper-thin layers of copper and insulating dielectric pose some real design and construction challenges. Especially the very high voltages, that threaten to cause arcing, require clean geometry with no sharp edges and no manufacturing defects. When we attempted to fabricate these parts ourselves, we did not succeed to produce them with enough consistency. It is simply outside of our capabilites to make in-house.This is why we decided to try alternative methods to produce them. This is where PCBWay plays an important role in making our project a reality.The flex PCB PCBWay offers has the capability of making high detail circuit structures on thin insulators, exactly fulfilling our requirements. The advanced processes that professional PCB manufacturers can offer will allow us to explore new design possibilites and have the advantage of superiour reliability. PCBWay especially has excellent prices and delivery times, that support our need of fast iterations and a larger number of PCBs.

Add-on board for Raspberry Pi. PWM Fan controlled by CPU Temperature, WS2812b led and Smart Power/Reboot switch.FLUSHHH is the all-in-one solution for the Raspberry Pi family.PWM regulated fan based on CPU temperatureMany cases for Raspberry Pi comes with fan in order to help cooling the CPU. But these fans are always on, and usually pretty noisy. FLUSHHH regulate the fan speed based on CPU temperature using little python script.WS2812B RGB LEDVery cool multi coloured light. Useful for adding visual signals or show some fancy styles visualization. Connected to Raspberry Pi GPIO pin 12 (BCM18 PWM0) and controlled by a little python script fully customizable.Smart Power On/Off and Reboot switch for Raspberry PiIts main feature is to control the power supply of the Raspberry Pi, providing a switch for Power On / Off and Reboot operations. An ATTINY85 programmed in ARDUINO manages vitality signals with Raspberry Pi.Just plug your micro-USB power supply into the micro-B connector of FLUSHHH, press the switch to power on the Raspberry Pi. Once started:pressure < 3 secs, rebootpressure > 3 secs, shutdownIn addiction, once installed the python script, FLUSHHH is able to check if a restart or shutdown has been commanded from Raspberry Pi and operates accordingly.BOARD INFOLet’s look at PIFLUSHHH closely:FLUSHHH connects to the Raspberry Pi GPIO HEADER:The board is powered via the USB connector. The GPIO pins supply power to the Raspberry Pi and handle the vitality signals.HOW IT WORKSAs soon as the power supply is connected, FLUSHHH waits for the switch to be pressed to power the Raspberry Pi.Once the switch is activated, the power to the Raspberry Pi begins. During this phase, FLUSHHH waits for the Raspberry Pi vitality signal via GPIO Pins. If after a timeout period there is no vitality, FLUSHHH turns off the power to the Raspberry Pi. For vitality signals, Raspberry Pi execute the script switch.py at boot.As soon as the vitality signal is received, the Raspberry Pi is correctly powered and normal operations can be carried out.In this phase the switch has 2 functions:pressure < 3 secs, rebootpressure > 3 secs, shutdownIn addition, through the vitality signal, FLUSHHH is able to understand if a restart or shutdown has been commanded by the Raspberry Pi and operates accordingly.In normal operation, Raspberry Pi execute the other 2 scripts:flushhh.py: for automated fan controlled by CPU temperatureled.py: for RGB led. The default script simply loop all colors with fade effect.INSTALLOpen a terminal on your RPi:cd /home/pi curl https://raw.githubusercontent.com/thinkedinthesea/FLUSHHH/main/install.sh > install.sh sudo bash install.sh These install all the libs and scripts needed.ABOUT MEIn the last 5 years or so i have started to design my own board for Arduino, Raspberry Pi and so on.The idea is to produce simple board that add feature to Raspberry Pi.I use Kicad for the PCB, and support from PCBWAY would be an enormous advantage to me.Having the ability to quiclky prototype boards make the testing and feedback process more efficient and simple, with effectively cost reductions.FLUSHHH will be presented in the online edition of MAKER FAIRE ROME 2020, link to board info.https://makerfairerome.eu/en/exhibitors/?edition=2020&exhibit=200074

Go!Subscribe: https://www.youtube.com/channel/UC88UigBH18Zn1UrtWgp2DPALink my page on Facebook https://www.facebook.com/Bihari-Lifehacker-108437444279042/Instagram: https://www.instagram.com/G-mail: rameshbseminaryr@gmail.com1) ARDUINO UNOArduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.2) RELAY MODULEA relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.The traditional form of a relay uses an electromagnet to close or open the contacts, but other operating principles have been invented, such as in solid-state relays which use semiconductor properties for control without relying on moving parts. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called protective relays.Latching relays require only a single pulse of control power to operate the switch persistently. Another pulse applied to a second set of control terminals, or a pulse with opposite polarity, resets the switch, while repeated pulses of the same kind have no effects. Magnetic latching relays are useful in applications when interrupted power should not affect the circuits that the relay is controlling.3) BLUETOOTH MODULEBluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves In the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.HC-05 module InformationHC-05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC-05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds.This module works on 3.3 V. We can connect 5V supply voltage as well since the module has on board 5 to 3.3 V regulator.As HC-05 Bluetooth module has 3.3 V level for RX/TX and microcontroller can detect 3.3 V level, so, no need to shift transmit level of HC-05 module. But we need to shift the transmit voltage level from microcontroller to RX of HC-05 module. Thanks Pcbway for Sponsership

Furthermore, the team consists of three main divisions and eight subdivisions.Hyperloop Manchester aims to participate in the first Hyperloop competition that will be arranged after the COVID-19 situation.Our Values:• Diversity – The team consists of around 80 members from multiple nationalities and different backgrounds. Hyperloop Manchester highly believes that the key of the solution to the problems comes from different ideas.• Teamwork – This is the core of Hyperloop Manchester. Everything in Hyperloop Manchester is done with teams and collaboration.• Passion – Everyone in Hyperloop Manchester is allocated in their teams according to their interests and passions. Therefore, every member is passionate about their involvement in the team.• Creativity – Tasks in the team are based on the creative ideas and solutions to improve the aspects of the Hyperloop pod.• Innovation – The value that essentially depicts the team is “innovation.” The team always aims to implement innovative applications in the designed Hyperloop pod and do research to continuously improve the Hyperloop structure.WHAT WE ARE CURRENTLY WORKING ONHyperman I is the Hyperloop pod designed by Hyperloop Manchester, which is powered by 18650 Li-Ion battery type using in multiple battery packs for each module. The electrical system consists of custom moduled built by using Teensy 4.0 microcontroller. O-DROID single board computer is at the centre of all controlling each module and interacting with the external environment which enables the user to track the sensor data, mapping, navigation, control, etc.Our pod, Hyperman I: Besides, the Mechanical team is currently working on the linear induction motor, braking and emergency braking, propulsion, levitation, and suspension. We can not share our design plans here since they are confidential.For high speed braking, eddy current braking will be used. For low speed braking, possibly, the friction braking will be used. Currently, this team is working on the electronics subsystems and the software implementation of the pod. The subsystems are categorised as follows: battery management system, power converter designs, motor controller board, brake electronics, and microcontroller motherboard. Hyperloop Manchester tracks and puts every development in electronics and software with reasonable deadlines for each task on Github: https://github.com/manchester-hyperloopThe diagrams for brake electronics, power converter board and track sensor unit are currently in progress. The help from PCBWay would be precious for us since it would be a big step for us to ease the manufacturing process of our prototype which we are aiming to start building it as soon as the facilities are open. The circuit boards for the modules are currently being designed by using Altium Designer. While designing the circuit boards, we are paying attention to create boards in adequate size and weight to keep the internal allocation of the pod as neat as possible. Since we are currently creating the pod infrastructure and established last year, we are now unable to share the 3D models of our PCB boards.

Step 1: Get All the PartsThe parts needed in order to build this project are these:An Arduino Nano ▶ http://educ8s.tv/part/ArduinoNanoThe fingerprint sensor module ▶ http://educ8s.tv/part/FingerprintSensorA 1.44” color TFT display ▶ http://bit.ly/144TFTLCDA small breadboard ▶ http://educ8s.tv/part/SmallBreadboardSome wires ▶ http://bit.ly/Wires3InOnePowerbank ▶ http://educ8s.tv/part/PowerbankThe cost of this project is around $30. If you take in consideration the technology that this project uses, this cost is very low. 10 years ago, projects like this would cost a few hundred dolars!Step 2: The 1.44" LCD Display1 / 2This display is very fast. It uses the ILI9163C driver. It has a resolution of 128x128 pixels and it can display up to 260.000 colors. It is very easy to use with Arduino and it costs around 4$.The display uses the SPI protocol in order to communicate with the Arduino board. We only need to connect 8 wires in order to make it work. Let’s start.Connection with ArduinoVcc ▶ 5V pin of the ArduinoGND ▶ Arduino GND pinCS ▶ Digital Pin 10RST ▶ DIgital Pin 9A0 ▶ Digital Pin 8SDA ▶ Digital Pin 11SCK ▶ Digital Pin 13LED ▶ 3.3V pin of the ArduinoAs you can see this display is very easy to use with Arduino. It is very cheap, very fast, it is small in size and it only draws around 30mA of current. I think it is a nice display to use in projects that don’t require a big display but color would be nice.You can get it here ▶ http://bit.ly/144TFTLCDStep 3: The Fingerprint Sensor Module1 / 3The fingerprint sensor module is small, and nicely built and it uses some advanced DSP (Digital Signal Processing) chips inside.The sensor works like this. It is an optical sensor, which means it analyzes the photo of a finger. It then renders the image, makes some calculations, finds the features of that finger and then searches in its memory for a fingerprint with the same characteristics. It can achieve all that in less than a second!This module can store up to 1000 fingerprints in its memory and its false acceptance rate is less than 0.001% which makes it pretty secure! Great! We get all that in a very easy to use module and with very low cost! It is a really impressive technology!You can get it here ▶ http://educ8s.tv/part/FingerprintSensorStep 4: Connecting the Parts1 / 3Let’s now put all the parts together.First we have to connect the fingerprint sensor module. We plug in the cable at the back of the module. Please check the attached photo.Fingerprint Sensor ConnectionBlack Wire ▶ Arduino GNDRed Wire ▶ Arduino 5VGreen Wire ▶ Digital Pin 2White Wire ▶ Digital Pin 3We are now ready to connect the display to Arduino.Display ConnectionVcc ▶ 5V pin of the ArduinoGND ▶ Arduino GND pinCS ▶ Digital Pin 10RST ▶ DIgital Pin 9A0 ▶ Digital Pin 8SDA ▶ Digital Pin 11SCK ▶ Digital Pin 13LED ▶ 3.3V pin of the ArduinoThat’s it! We are ready to power up the project. As you see it works fine! Easy isn’t it?Step 5: The Code of the Project1 / 3Let’s now see, the software side of the project and how to enroll our fingerprints to the module’s embedded memory in order to recognize them.We need to download some libraries. First of all we need the Adafruit Fingerprint library, the Adafruit GFX library and the Sumotoy’s library for the display.https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Libraryhttps://github.com/adafruit/Adafruit-GFX-Libraryhttps://github.com/sumotoy/TFT_ILI9163CFirst of all we have to upload the enroll example to our Arduino board. We go to File -> Examples -> Adafruit Fingerprint Sensor Library -> Enroll. With this example program we can store fingerprints in the FLASH memory of the module. We upload the sketch and we open the Serial Monitor. The program ask us to enter the ID to enroll. Then we place the finger on the sensor twice as we are instructed and the fingerprint is stored! You can store as many as 1000 fingerprints this way!Now, let’s load the code that I have developed. Thanks to Adafruit’s libraries the code of the project is very simple. Let's see a small part of the code.We start the sensor and the display, and we check for a finger on the sensor every 50ms. If there is a finger on the sensor we request the module to search if that finger is enrolled in it’s memory. If it finds the fingerprint in the memory it returns that fingerprints’ ID. Next it displays a welcome message and locks the screen again after a few seconds.As always you can find the code of the project attached in this tutorial. Since I update the code from time to time, for the latest version of the code please visit the project's website: http://educ8s.tv/arduino-fingerprint-sensor-module...Fingerprint.inoStep 6: Final ThoughtsI am really impressed by the performance and the ease of use of this fingerprint sensor module. With very low cost we can add biometric security features to our projects. That’s amazing. Projects like this would have been impossible for a maker even a few years back. That’s the beauty and power of open source hardware and software. After this first test I am going to use the fingerprint sensor module along with an electric lock in order to see if we can use this sensor in a real life situation, so stay tuned. Please let me know your thoughts about this sensor, in the comments section below. Thanks!Thanks Pcbway for Sponsorship 😊

It was designed as a development board for young developers.And it is designed for high school and middle school students to learn to code. it has many sensors on it. They have a five led, rgb led, two button,buzzer, ldr, ntc, temperature and humidity sensor, lcd, ultrasonic sensor and arduino UNO. This card, which contains many sensors and will be free for our students. And will be able to code with any program they want.(Arduino IDE,Scratch,MBlock etc.) This board is portable because it is small in size.I think it is important for disadvantaged individuals. Your support will make me and our students happy.This company has always supported us, so thank you very much.I am waiting for your support. Thanks pcbway :)
