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.

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino.

Achieving accurate 13-bit color can be achieved with a dual buck LED-driver architecture that has I2C control. It’s able to drive multiple LEDs or strings of LEDs with high current and high ...
