Mike Baxter has created a guitar using two Arduino’s and a servo. The first Arduino controls a Midi file to produce a specific note, and the other to control the servo. Then, each note is simulated by stretching the string at the guitar is played. While Mike’s guitar is unique, it probably won’t give Eddie Van Halen a run for his money anytime soon.
