I’ve made some progress on my “Guitar Hero Robot” mod. I dissected a used “Guitar Hero” guitar and wired its inputs to the niftyArduino Duemilanove. Now the sensor input feeds the notes back into the X-Box.
The robots insides
I tried to keep the cost of this project down. The Arduino does all the filtering of the sensor input, converting a shakey analog signal into an absolute on or offsignal (thank you Chris Cordingley).
I will post a How-to along with the source code as soon as I’m finished.
I set up an Arduino to read the notes on Guitar Hero and flash an LED to that corresponding note.
I used this ambient light sensor, from sparkfun.com to read the changes in value on the screen. When something bright flashes in front of it, the Arduino will turn on an LED for as long as that brightness is there.
Take it one step further and you can have this robot play Guitar Hero for you.
