LED WS2801 component
A simple chained RGB LED controller IC allowing multiple LEDs to be controlled using a serial data stream. Allows RGB LEDs to be driven with full 24-bit colour depth. Allows single chains, 2D arrays and 3D cube formations to be simulated. Supports Bit Banged or SPI peripheral based data modes.

Examples
RGB Mood Light
A simple example using three potentiometers to set the individual Red, Green and Blue channels of the LED colour.
Animated Light
A simple example which picks a random colour assigns it to the first LED, then shifts and repeats.
