Building a 3 x 3 x3 LED Cube controlled by an Arduino?
I built a 3x3x3 LED cube and tested it. Since I'm new to electronics and micro programmable processors I'm having a difficult time connecting the cube to the Arduino and haven't had much luck getting information fundamental enough for me to grasp. I've tried a few ways and as you would expect, trashed a few LEDs to say the least. Since the digital pins output 5 volts I can't figure out how to connect the 9 anodes and the common cathode per level. Can anyone help?
