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.

Arduino has created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. “Whether you’re working on a connected ...
