What is an LED Cube?

An LED cube is an extension on the LED matrix, it is basically a 3-D matrix of LEDs. It works in exactly the same way as the LED matrix does, one LED is turned on at a time yet they are turned on and off so quickly it gives the impression that they are all on constantly. The wiring is slightly different in this case the cathodes on each level are connected together while the anodes are connected in columns, this means for a 2x2x2 led cube you only need 6 control lines as can be seen in the image below:
