LED CUBE

A Typical 3D LED Display is a collection of LEDs, somehow connected and arranged in a 3D pattern and controlled so that the LEDs can be made to turn on and off in a controlled manner, thus creating interesting and pleasant patterns of light.

The LED cube has 64 LEDs (4x4x4). Each LED is dedicated to an IO port in a microcontroller. LED cube relies on optical phenomenon called Persistence of Vision. If you flash an LED really fast it will remain in your retina for some time even after LED is switched off. By flashing each layer of cube very fast after one another it gives the feeling of 3D.

With this setup we will need only 16(anode) + 4(layers) IO ports to control each LED.
