Find an RGB LED for your driver circuit on Ebay

An RGB LED Driver circuit obviously needs some RGB LEDS and you can find some great bargains on Ebay.

There's a single RGB led controller circuit that shows the principle of using PWM to control an RGB LED circuit on this site.

To make a 3D cube for each layer connect all the R G B pins to individual microcontroller outputs on each layer then connect each individual LED ground pin to a microcontroller pin.

For the RGB LED matrix cube Justin made, he used 18 pins to drive 27 LEDS as follows
Each layer has 9 leds - 9 uC pins to each LED GND (columns)
Each layer has 3 R G B connections - 3 R,G,B x 3 layers = 9uC pins.

Justin found some RGB LEDS shipped from Hong Kong 100 for only $35. Below is a direct link to ebay.com.
