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.

Resistors used: Red - 82 ohm, Green - 56 ohm, Blue - 56 ohm. Allowing approximately 20 mA to flow through LED. Cathode (-) pins of RGB are connected to 8-bit PWM pins of Arduino for voltage control.

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

The original RGB LED chain controller has one button that changes the LED lighting mode. There are 10 modes in total. In this project, I created a controller from Arduino Nano, a relay, DIP switch and ...
