[Arduino] 3D LED Cube

After a first try with tiny space between LEDs (see last post), here is another try with enough space to build a proper cube, still following MakeZine instructions.

The fun parts were to add transistors to the board, allowing to get more power for each led level, and the programming: Persistance-Of-Vision and binary manipulation for led on/off switching.

If you need it, you can download the arduino program related to this circuit.
