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.

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.

This project is a custom LED PCB made as a birthday gift for my niece. It formats her name with RGB LEDs on the board and animates different color patterns using an Arduino Nano.

If you would like to learn more about the new Arduino Maker Nano RP2040 will be pleased to know that a review has been published to the official Raspberry Pi MagPi magazine website this week by Phil ...
