You can also use it as a mood light, or create your own "ambient device" that gently notifies you of new emails or instant messages! The RGB LED CUBE KIT is supplied as a partly-assembled kit:The controller board is based on an Arduino-compatible 8*8 LED RGB Matrix driver board. All RGB LEDs are soldered to the plane PCB, and tested okay. You just need to solder and assemble the 3D matrix. The RGB LED CUBE KIT comes with a sketch pre-installed that runs through a test pattern.
