With no new song downloads for Guitar Hero on the Wii (as of yet), what to do with that controller once all that ‘rawk’ has grown tired? Jason writes –
This posting describes a project in which the author gets an Arduino reading input from a Wii Guitar Hero guitar. Included is a function library to simplify the task of handling Wii guitar data in Arduino sketches, and a demo sketch showing off the library’s functionality.
This could be a quick and easy method for creating your own digital instrument – nice! - Wii Guitarduino
