Introduction: Modular LED Lighting system.

Overview: I am going to begin working on an arduino based, modular LED lighting system. The idea is to produce a series of LED lighting modules that can be daisy chained together to provide a lighting system for room ambience or possibly as a low cost wash and floor lights.

Each modual will contain 8 total LEDs, 4 RGB bright LEDs (0.2-0.3 watts), 1 each of super bright (1 watt) Red, Green and Blue LEDs and one indicator LED for debugging. The goal is to make each LED (or sub-led for the rgb LEDs) individually controllably and dimmable. This will allow for a wide range of effects and colors including fades, cycles and chases. The three super bright red, green and blue LEDs will allow for even mor flexibility by providing a high broghtness source. 

The system will be controlled by an arduino and each module will be connected over SPI. The arduino will provide the command stream to each module. Eventually I would like to add control of the arduino via a computer so that the system can respond to computer events such as remote control commands, emails, network events, music etc...

Goals:

• High module limit (200+)
• High update rate (30hz or better)
• Daisychain-able
• Individual LED control
• 1024 brightness level control or better
