Me and a friend would like to build a large (a little bigger than human) led matrix. The number of pixels is less important than the total size. We are not sure if we want rgb or white leds. We consider to work with the arduino mega adk because of additional android experiments. We are totally new to doing arduino projekts, so it would be best to follow a route that has proven itself. We are waiting for a probable funding of the projekt of say about 500 euro's
Does anybody know a way to connect and control a few hundred lights? We can do some soldering, but are far from electronic geniusses. Also for the programming we hope to use open source. Of course we want to invest time to study a bit, we have one or two days a week for three months to do this.
What to do? Where to start?
