Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Here’s a handy hack for an Android controlled, Arduino driven, RGB light setup. [Kerimil] recently wrote up this project on the Arduino.cc, and is sharing all of the source code and plans. While many ...

WARNING: Since the IoT RedBoard with ESP32 has a system voltage of 3.3V, the logic levels is 3.3V instead of 5V on the RedBoard with ATmega328P. Thus, the analog reference voltage for the ...
