This is for those geeks who feel this game is impossible. Now there is a guitar hero robot designed just for playing Guitar Hero! It uses color sensing on the screen to detect when to press the buttons, and it uses solenoids like fingers to press the buttons on the actual Guitar Hero guitar. It’s fascinating to watch the robot while it gets a near perfect score every time! I’m sure if they work at it a little more they could perfect it to get a perfect score every time! Or you could try making a better one using the Parallax Propeller chip. There are photodiodes on the Parallax website for color sensing in the components section. A few of those and the solenoids just might do it, but you might even be able to use servos for testing purposes (assuming you can get them to push the buttons down all the way). Have fun, and soon you’ll be able to beat all your friends!
