In this tutorial about controlling a pedestrian sign with an Arduino you can learn a few important things. #1 How to control relays with an Arduino, which is really useful for a ton of different projects. #2 How to use an IR remote to control your Arduino, another cool technique. #3 Never trust a crosswalk sign with an Arduino hanging out of it!

My latest project is controlling a pedestrian sign with an Arduino, so it will automatically step through the states of walk, flashing don’t walk, and solid don’t walk. In addition, I added infrared remote control support so I can use a remote control to turn the sign on and off, set it to a particular state, or start the cycle.
