This is another LED-Matrix with some extra features. You see the LCD-Display in the picture on top and a wireless touch controller on the lower left side.
The main body is a matrix of 36 LEDs, however each single LED can light up in red or green. Thus we have 72 lights in total. There’re 12 cathodes and 12 anodes.
On the logical side we have 24 discrete tranistors, a 24 bit shift unit and an ATmega8 micocontroller. There is absolutley no magick in it.
Eveyhing is made for interaction and can be used as a playing field. The default app is a Connect 4 Game, but even some another games (like Snake etc.) could be possible.
