What do you get when you combine five LED enthusiats, a free weekend, an Arduino and hundreds of LEDs? The LED wall, which is a massive pegboard (size – 53″ x 31″) fitted with a matrix of 350 LEDs. The matrix of LEDs can be controlled by switching each LED on and off like pixels via a web interface which anyone can access to make your own designs.
The concept is similar to these ithernet enabled Christmas bells. An ioBridge sits between the LED board and the web interface which is connected to an Arduino. The Arduino sends the signals to the LED driver chips which finally creates the display on the wall. The programming is done with Lithium, a lightweight framework for PHP. The arrays of LEDs are controlled by MAX6953 LED driver chips.
You get to see the messages via a live web feed, but the web interface seems to be offline right now.
