The Traffic Light Arduino Platform is now wireless. A independent console (powered by an Arduino) with three programable buttons transmits a code signal using XBees to a receiver. The receiver (also powered by an Arduino) decodes the input and turns on and off the traffic lights as well as play music accordingly.

The TLA Platform isn’t finished yet. There are still more features to add, and much more code that could be written for different uses, but for now, it’s ready for some people to come and play with it at my lab demo.
