Here is an experiment with an 8×8 LED matrix, driven by a MAX7219 IC, controlled through an Arduino micro-controller board. A custom PCB has been made by Tan from DinoTech to tidy up all the wires connecting the LED matrix and the IC. It comes with a separate 12V power supply, in order not to drain everything from the Arduino board.[more]
