LPD6803 RGB LED Strip with an Arduino
I have this strand of LEDs/Controllers and I've made it work with the LPD6803-RGB-Pixels library.

To connect the strip correctly:


Di (Blue Wire) = VCC -> Connect pin: Vin on Arduino.
Ci (Green Wire) = Data -> Connect to pin: 2 on Arduino.
St (Red Wire) = Clock -> Connect to pin: 3 on Arduino.
Li (Black Wire) = GND -> Connect to pin: GND on Arduino.


Once the Arduino is programmed, unplug USB cable, and only use the 12V supply.

Hope this helps.
