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.

Right, let's get straight to the point. This is a little eye-candy circuit which continuously cycles an RGB LED through the colours of the rainbow. The speed at which the colours change is adjustable.

[Synoptic Labs] stumbled upon an RGB light strip with individually-controllable LEDs. The strip uses 5 volts and is controlled by an HL1606. Because the strips are hard to find, this chip is mostly ...
