Using a Teagueduino and a few inputs and outputs, we put together a physical side-scrolling video game. To control it, there's a knob on the side. As time advances the game gets faster and faster -- can you avoid all the obstacles and make it to the end?
Watch the second half of the video for an overview of how everything is hooked up.
