A crafty Guitar Hero DIY-er has built a little project with possibly startling implications. The includes ambient light sensors in front of the television which are triggered by the light of the notes on screen during Guitar Hero gameplay. The sensors trigger an Arduino to turn on LEDS on a nearby setup. In the video (which is after the break) you can see the entire thing in action -- which maker Joe says can eventually lead to a rig which plays the game for you. The horror![Via Make]
