Simple Basic Weather Station
🙂 Jul 27,2020
Probably a common project and maybe already done for you, this project represent an adjustable digital clock, but also we can see the temperature and humidity of the room every minute. The clock can be adjusted using 3 push buttons: press P1 to enter in menu, P2 -> '+' and P3 -> '-' , for hours and minutes. I placed the modules in a such way because I will use jump wires, so the location of the modules on the pcb doesn't matter for me. I found the original project on internet, with rtc mod...

Pulse Generator
Javier Alonso Valdesueiro Jul 27,2020
RF pulse generatorshield for arduino UNO.Frequency goes from 1.5 MHz to 2.5 MHz (filter can be changed)Minimum pulse width of 5 us and minimum repetition delay of 200 ms.The output is fixed to 1V but R4 can be updated to a potentiometer.Please refer to dayspringTECH designs when use it.

8x8 LED Matrix Circuit using 74HC595
🙂 Jul 24,2020
I drew this circuit out of the need to reduce the number of connections to the Arduino platform, it uses 2 shift registers 74HC595 together with 8 current limiting resistors. It can be seen as an alternative to circuit with MAX7219. It works perfectly.Note: The matrix used in this circuit is very small, probably the smallest version made.P.S. I am not the original author of this circuit, I just draw it.

USB Component Tester
Baweja Jul 24,2020
USB Component Tester in a keychain is a universal testing device for electronic components with three or lesser pins. It can automatically detect the plugged-in electronic component and measure the desired component parameters without having the user to manually select the component type, unlike the multimeter. It is based on the popular AVR TransistorTester. With a custom application built using electron, USB Component Tester provides the user with all desired component insights with a cle...

Lego sensor adapter - Use Lego EV3 sensors with Arduino
Jochman Jul 21,2020
Intro:For quite some time I was working on an educational robot. Thanks to Leaf Award I started working on Robot Cing (https://hackaday.io/project/93532-robot-cing-educational-robot-for-everyone). Unfortunately, it is still not done because I keep finding things that can be improved and I am writing manual where programming would be explained as well as basic hardware functions. In the meantime, I created this adapter board which currently allows you to connect Lego EV3 color sensor as well as a...

EPROM Emulator based on Arduino.
MGH-Kris Jul 20,2020
EPROM Emulator is a tool that can temporarily replace an EPROM memory chip inside your "target" device. You can plug it into your computer and "upload" a new version of code in secondsImagine you are developing software (well, firmware more likely) and you need to change the “program” in your EPROM memory. That means, remove the EPROM from its host computer, subject it to 20-30min of UV light exposure, program it with EPROM programmer, and re-install it on the host computer. The entire process i...

Music Reactive Multicolor LED Lights Board
KILIC Jul 19,2020
Music-reactive multi-color LED lights project. In this project, a simple 5050 RGB LED strip (not the Addressable LED WS2812), Arduino sound detection sensor and 12V adapter were used. So how does it work? If you take a closer look at the Arduino IDE source code of the project, an analog value comes from the Arduino sound sensor (this varies according to the intensity of the music), after that a threshold value is defined (just like 0 to 1023), if the value from the sound sensor does not match th...

DIY Arduino Multifunction Energy Meter
Green Energy Jul 17,2020
In this tutorial, I will show you how to make an Arduino based Multi-function Energy Meter. This little Meter is a very useful device that displays important information on electrical parameters. The device can measure 6 useful electrical parameters: Voltage, Current, Power, Energy, Capacity, and Temperature. This device is suitable only for DC loads such as Solar PV systems. You can also use this meter for battery capacity measurement.The Meter can measure up to voltage range from 0 - 26V and a...
