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.

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 ...

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 ...
