The Franclin oscillator is composed of the LC resonator and the phase inverting amplifier. The digital capability could lead LC meter which was calculating L or C value from the basic capacitor's capacitance by solving correlated equations from the oscillation frequency number.[To compose the Franclin oscillator and MPU ] A certain Eastern European electronics engineer found this idea in along 1990’s. After then the Australian Ham magazine had picked it up as a technical article. At that time AADE( On his WEB he wrote that he had been a Boeing engineer.) had already introduced this circuit, produced, and sold it as a product for HAMs. In Japan, the Strawberry-Linux company and CYTEX company had developed a clone and sold those for HAMs.Below is an explanation of how to calculate the capacitance or the inductance. // a. To oscillate and measure the frequency of F1. // b. To add the standard capacitor paralleled and get the frequency of F2. // c. There is two-equation for the circuit. F1＝1/2πsqrt(C1L1), F2=1/2πsqrt((C1+C2)L1). // d. F1, F2, C2 are the valid value. We could draw C1 and L1 by the mathematical process. // e. When you put L2 serially and get F31, you shall draw L2 value out of the equation. Also C3 by F32. F31=1/2πsqrt(C1*(L1+L2)), F32=1/2πsqrt((C1+C3)*L1).I use 74HCU04 inverter IC for the Franclin oscillator. For the sake of switching the standard capacitor, I had adopted the relay. If you use semiconductor switching, accuracy may decline. The two-pole two circuit switch is necessary for LC change. I use i2c interfacing LCD for display.There are the circuit diagrams below site. https://cdn-ak.f.st-hatena.com/images/fotolife/n/nobcha23/20200714/20200714202214.jpg https://cdn-ak.f.st-hatena.com/images/fotolife/n/nobcha23/20200726/20200726214857.jpg

WHO I AMMy name is Bruno I am 18 years old, I currently live in Argentina, Buenos Aires.I have a few days left to receive an electronic technician in an important school in Buenos Aires.I am also very fond of sports, I like Futsal, Tennis and water polo. The latter I train to this day, the truth is a little known sport but very fun. I chose electronics since I was a child because I like it too much and it is very fun, also always had the dream of making some contribution or help to society.Project descript_ionAs I mentioned earlier, my dream is to help or make a contribution to society. Thinking about how I could carry out this dream, it occurred to me to mix the two that I love the most: electronics and water polo. In the club where I train there is not so much budget to buy the electronic boards that the sport requires. So my idea is to make one of these boards (similar to the one in the photo) from my knowledge that I acquired during these 6 years of electronics. At first I have to do tests to achieve a correct programming and then carry it out in a big way. Next I will leave some photos of the first test plates that I need.At first I plan to do all the tests on arduino and once it works correctly I plan to take it to another microcontroller.Words to PCBWayI met this company through a friend who recommended it to me for its excellent work. I really like what they propose with the sponsors and the truth is something innovative that would serve very well for the Latin American countries, which do not count as much capital to start their project. This is an incredible help so that everyone can pursue their dreams.On the other hand, I look forward to this great help from the company and I look forward to your help to carry out this project. From now many thanks and greetings!

This is a DIY handheld gamepad, made using ESP32 microcontroller. You might have seen such game controllers before. But most of them use Arduino. Or more specifically Arduino pro micro or Leonardo board. Because these boards support HID, or human interface devices over USB. but esp32 doesn’t have such feature. So how do we do it? Well, esp32 does have BLE, or Bluetooth low energy, which we can use to communicate wirelessly, over Bluetooth.So we have ESP32 module, as the central controller, then we have the USB type-C port, and a 3.3v regulator to convert 5v to 3.3v. Then we have the programming circuit, using ch340c usb to serial converter with auto programming mode and auto reset circuitry using duel transistors. We also have a battery charging circuit, along with overcharge, and over discharge protection. Which then boost up to 5v, using the boost converter ic. Next we have the joysticks, D-Pad buttons, trigger buttons, Neopixel LEDs, i2c port. And finally a 3way switch, to toggle between USB power and battery power.The gamepad has2 analog joysticks2 trigger buttons2 D-Pads6 addressable RGB LEDsand a i2c portIt can run using 2 18650 Li ion cells, which can be changed using the USB type-C port. And it can also be used to program the microcontroller. The design is inspired by the new ps5 controller, to give it a better look. The GPIO4 is connected to the battery using a voltage divider. So that we can measure the battery voltage. the NeoPixel LEDs will indicates if the controller is connected to a device or battery voltage is low.The code is based on BLE Gamepad library by lemmingDev. In the code I have defined all the GPIO pins for different inputs. Then in the setup there are some initial led animations. And as soon as the board is connected to the device, all LEDs will turn Green. And it will check battery voltage, in a time interval, which is defined earlier. Then we get the button states, and set the gamepad buttons accordingly. Then we take the analog inputs, and map it to suitable values. And finally set the axis according to the values we received. After uploading the code open Bluetooth menu on your Smartphone or PC and you will see a new device pops up. click on that to connect it and you are ready to play.

This Arduino Uno is the same form factor as the original Arduino Uno, but is made to be solderable and cost-effective for education. The design costs less than $15 per board. All of the parts are either through-hole or large package surface mount, with the exception of the Atmel ATMEGA16u2, which is a VQFN. The ATMEGA16u2 will be pre-soldered before the seminar.I designed this board to teach soldering to Freshman and Sophomore engineering students at Cleveland State University about soldering and PCB design. I will be teaching 100 students over two weekends how to solder a PCB in hopes to inspire students to work on projects outside of class.The course will begin by going over the basics of what a PCB is and how they are made. We will then briefly discuss how this board was designed in Eagle and how to design and order a PCB for your own projects. My hope is that in the future, I will be able to start an elective course completely dedicated to teaching students how to design their own PCBs and then order them from places like PCBWay. We will then move to a brief discussion of soldering and how it works. Each of the 20 students will receive a soldering iron, a VikeDuino PCB, a USB-B Cable, and all of the components necessary to build the board. Using a microscope attached to a projector, I will demonstrate part by part how to assemble the board and how to solder. Once soldering is complete, we will load the bootloader to their board and upload a sample program. We will then program the boards with a test script___ and hook up a test circuit to the Arduino to verify that each pin works.After the class is complete, each student will have soldered his or her very own Arduino Uno and will get to keep the board for no cost. This will give every student the opportunity to work on Arduino projects outside of class, without having to purchase an Arduino for themselves.The Gerber Files for the PCB can be found on my Github: https://github.com/RowdyRutabaga/VikeDuino_Uno

This project RFID Door Lock System is beneficial in places where the door needs to be locked and opened a lot of times, so we just need to tap a card to lock and unlock it, which makes it very easy to use. I decided to make it for my project, so that it be beneficial for the school as well. It works using the RFID Module for arduino, in which when the card is placed, it sends the signal to servo motor using arduino, which moves the lock back and forth. This project can be used in places where only authorized personnel are allowed, as they can be given the RFID card to unlock and lock it. I (Saksham Khurana) a student from INDIA, would like to avail the sponsorship facility to make this project so that it can be used by more and more people.Material Required:- > Arduino nano> Lcd 16*2> servo motor> RFID module> PCB> latch> Transistors> Buttonif i would receive the sponsorship from PCBWay then i would ask all my friends and fellow mates to make PCB purchases from your company.Thanks and RegardsSaksham Khurana

Hello guys welcome to my blog, my name is Maria Ramirez, today I bring a great project for those fans of clean energy, in this case I bring an MPPT solar charge controller based on arduino.This charger has an efficiency close to 98% since it has a synchronous source controlled by means of the arduino, this charger is ideal for applications where it is required to feed large powers and it could even be implemented to charge the batteries of electric cars.I designed this charger since in many parts of the world, unfortunately they do not have electricity in their homes, so I thought that this charger could be of great help since it could be used to power lights, computers and even refrigerators, if you have enough batteries, but nevertheless design this charger since today the world demands a change towards that the energies we use must be clean energies to help the planet, and of course, to learn from them since they are the future.Initially this charger is designed to operate solar panels with a power of 300 watts each for a total of 1200 watts Although something that I must highlight is that the charger has a maximum input voltage of 80 volts and a maximum output current of 25 A, This charger is designed to work with various battery voltages, it can work with 12 V - 24 V - 36 V - 48 V batteries, in addition, if the charging algorithm for each type of battery is taken into account, this charger can charge batteries of all.I decided to design a synchronous BUCK type converter since they offer us a very high efficiency Therefore we will waste less energy and at the same time our charger will be more efficient and smaller, this Source will have a switching speed of 60 khz and will be controlled by means of Our arduino which by means of a resistive divider at the output of the Source and a current sensor, will analyze the power delivered to our batteries and modify the PWM always in order to find the highest possible power.This design is very versatile since it is possible to increase the power in a very easy way, we will only have to change mosfet for much more powerful ones depending on the power we want to obtain, in the same way we must take into account the LC output filter of the Source since we do modify the input voltages We will have to recalculate the filter, speaking of the filter I want to highlight the importance of quality What must these components have to obtain the calculated power, since the inductor must be able to withstand the maximum current of the source without get to saturate, since if it saturates this it will modify its value also modifying the cutoff frequencies of the filter and directly affecting our quality of energy that we obtain from the charger, in the same way the capacitor must be of very good quality to ensure the least possible ripple at the source outlet.Thinking about the future, it would be a very good idea to design a system to analyze the monthly energy production, and in this way have more control in our system, a charge controller could also be implemented for the batteries that need it. How is the case of lithium batteries, and in this way always keep the batteries balanced and be aware of the entire system in general, the efficiency of this charger will depend directly on the quality of the mosfet and the coil used.This charger implements several protection systems, for over temperature, for short circuit and for overload, in all cases, turning off the DC - DC converter directly, in this type of sources it is of utmost importance to have a good system on and off the mosfets Jackie this way we will avoid the accidental on or off of any of the mosfets causing a short circuit in this case, we must also take into account the dead time of the mosfets in the Source to guarantee the correct operation of the source and avoid heating in vacuum of the mosfet.When we talk about high-power converters, it is essential to take into account the correct design of the PCB since a bad design of this could cause significant losses in the source and its malfunction, therefore it is important to take into account the correct dimensions of the tracks depending on the intensity of current that circulates through them, that is why in my PCB design I left some tracks without antisolder to reinforce with tin, since a significant amount of current will circulate, it is also of utmost importance to ensure correct cooling for the mosfets, since depending on the temperatures of these, we will have more or less limitation regarding the amount of current that they can switch, in addition to the impact that this has on the useful life of semiconductors.Without more to say I say goodbye and I hope you enjoy this project as much as I do, any questions or suggestions in the comments, thank you very much for your attention guys.:)

PCBWay, hello.I want to make a project of a beautiful and original Christmas tree. The outline of the Christmas tree consists of 5 patterned parts. The basis of the Christmas tree is 16 address RGB LEDs WS2812B. An 8-bit STM8S103F3P6 microcontroller will control them and create a variety of effects. There is a button in the project, it can be used for various purposes, for example, you can switch effects or change the speed of effects or other functions.Structurally, the Christmas tree is made on a 2-layer printed circuit board.This is top layer:This is bottom layer:The dimensions of the Christmas tree do not exceed 10x10 centimeters. The Christmas tree has graphic elements on the theme of Christmas and new year. Also, for an additional pattern, asterisks are used on the same line with LEDs, this gives a special charm to the project.Thanks to the use of RGB LEDs, you can get practically all shades of colors, including transfusion from one color to another, as well as rainbow effects. It should look great.For example, a charger from a cell phone with 5V and a load current of 1A is suitable for power supply. As an alternative power source, you can use the computer's USB port or portable power bank.Such a project is perfect for both home use, and for work in the office or other areas of application, for example, it can decorate the interior in a restaurant or cafe. In addition, everyone will be able to repeat this simple and inexpensive project and order excellent quality printed circuit boards from PCBWay. In the conditions of a crisis and a worldwide pandemic, we electronics engineers and home-made people will be able to make our world a little brighter with the help of LEDs and a soldering iron.But, for the implementation of the Xmas Tree project, i need your sponsorship. Sincerely, Ivan.

I created this project Inspired by Turkish brother Emre Konca's project, Turkduino Uno. I designed AZduino-Uno as a development board for young developers. It is designed for school and university students to improve their skills. This is actually also an Arduino Uno. 20% of Azerbaijan's territory has been occupied for about 30 years. We liberated these lands in 44 days. It was a great chance to celebrate this victory and to make our students love electronics.My Youtube Channel: https://www.youtube.com/NizamiKalbaliyevMy Instagram Profile: https://www.instagram.com/Nizami.KalbaliyevThe components we use are suitable for every student, as they are both easy-to-find and inexpensive materials.I added a DFplayer to AZduino Uno. I connected DFplayer's Tx Rx pins to AZduino Uno pins 10, 11 respectively and added a 1k resistor betweenpin pin11 and Rx(DFplayer) as requested in DFplayer's manual. You can use the DFplayer by connecting an 8ohm1w speaker to the SJ1 on the AZduino Uno.I added cuttable jumpers between the pins of DFplayer and Atmega328p. If you want to disconnect Atmega328p with DFplayer, you can cut these jumpers.We would like to thank PcbWay for its unwavering support for this project!!!

Temperature and humidity using the DHT11 sensor and LCD display 1602 with an I2C module and a relevant code.Here I am going to display the temperature and humidity using the DHT11 sensor and LCD display 1602 with an I2C module and a relevant code.Now I have been struggling with this project for like hours now. But at the end I find out I did not have the correct knowledge. So people it is very important to know what you are making. In this case I recommend you to go through the page and not just copy and paste the code.Now, this project uses a DHT11 temperature and humidity sensor with the three pin but you can also use any other sensor the changes in the code should be as per the model. I have used Arduino UNO for this project.

Hello guys, my name is Dayana and I am an electronic engineer, this time I would like to share with you a project that is about a high power DC-DC buck source controlled by arduino.I decided to develop this DC - DC converter since there are many fake high power converters on the market that promise to handle many amps but at the moment they are very fragile and inconvenient.So I developed this very robust and versatile DC - DC source, to be used in any project, where it is required to handle large powers and currents that a common source would not handle, the design of this source is initially intended to be used in non-current currents. greater than 45 amps, and an input voltage of 100 V, (depending on the mosfets and diodes used).Although the idea by itself sounds very crazy, this source works at a frequency of approximately 60 kHz, which is a very considerable frequency for its dimensions, I decided to use this frequency since we can reach efficiency values ??greater than 90% very easily, we will only have to calculate the components correctly to use and put the source to work.Thanks to the current sensor incorporated in the PCB, we will be able to have complete control over the current that circulates through the output of the source, in this way we will vary the duty cycle of the source and by magic we will have a high DC - DC source. Power with current limit ideal for charging lithium batteries or any other type.Finally, I would like to give some guidelines for operation and calculations to take into account for the start-up of this source, first take into account the maximum input voltage and the maximum output current, since based on these data we will have to choose between a mosfet or another for our source, I have to say that in this source the inductor is of vital importance so as not to have a very strong ripple at the output of the source, therefore I recommend using an inductor that easily supports the maximum current output and we will prevent it from saturating and altering the values ??of the calculations made, thanks to all

The concept of internet has been accepted since the day it entered human life, but with the technological developments experienced, it has emerged as the internet IoT concept. IoT, which has gained popularity in recent years and is preferred by distinguished researchers.IoT encompasses everything connected to the internet. It is used to describe objects that interact with each other. In simple terms, the Internet of Things (IoT) refers to the tendency to connect all kinds of physical objects to the Internet. The Internet of Things is used in everything from common household appliances such as refrigerators and light bulbs to medical and wearable devices and even smart cities. Specifically, IoT is a system of physical devices that receive and transmit data over wireless networks without human intervention. This is possible by integrating computing devices into objects with the help of sensors.In this project, a system that can be monitored from outside has been created.For example, you are engaged in agriculture.There will be water pump or electrical components that you need to control remotely.These components have been stabilized by using Esp-12 in order to be a system that can be monitored and intervened remotely.Endless thanks to PCBway for their unwavering support as always.

I am Sedat a undergraduate electric-electronic engineer student. I recently started RC Airplane hobby and I purpose develop myself in this hobby step by step in systematic manner. Therefore, I ask PCBWay for sponsorship my BLDC & Servo Motor Tester project at very early stage of my hobby as it can be seen by simplicity of my project.One week ago I needed a PWM signal generator to test my new BLDC motor. My aim was to measure thrust data of my motor at different duty cycle values of PWM signal. I made a market search and I found very common servo and BLDC tester which has a potentiometer, input and output ports structure. As my aim was to measure thrust data at different duty cycles, I should know exactly at which duty cycle I am at. However, the products that I found in market does not contain any display. For this reason, I designed a circuit which includes a Arduino Nano, a 16x2 LCD display, 2 potentiometer (one for adjusting duty cycle and the other for LCD contrast setting). Then, I implemented circuit on a stripboard and I verifed it with tests. Right now, I want to conclude this BLDC and Servo Tester project by replacing stripboard with professional PCB because PCB will avoid loose cable contacts and other possible failure reasons when testing motor. Also, replacing stripboard with PCB will gain better and finished project appearence to circuit.I always see sponsorships of PCBWay with my favorite youtube channels on different countries from all around world and I hope PCBWay might be sponsor my project too generously.Best wishes,Sedat

## DESCRIPTIONMy name is Parmesh Singh, from India. i have designed a PCB to driver a 16X2 or a 20X4 LCD using I2C port.you can program 8 different address that means you can driver up-to 8 LCD panel using only 4 wires i.e Data, Clock, Power and Ground.The best part is its small enough to hide behind the LCD panel but big enough to use a DIP-8 chip that is PCF8574.With this you can adjust the Contrast as well and also control the back-light using I2C port only. this module works on 5v and consumes less power.I'm also attaching the PCB layout and schematic.*Schematic*Top Layer*Bottom Layer*Both Layers
