From the Adafruit Flickr pool, LenP17 is making an a fantastic Boarduino-based Guitar Hero cheater…DaveyBot-

Test of the Arduino interface for DaveyBot. The Xbox is playing Rock Band 2, the computer software is analyzing the game images and sending commands over USB to the Boarduino (shown in the video) and the Boarduino program is turning on & off the LEDs. Those LEDs represent the switches on the Guitar Hero controller. The next step is to wire the Boarduino into the guitar controller.
