Make a Guitar Hero Control with strings using MaKey MaKey. via instructables
Utilizing the MakeyMakey program, we have constructed a guitar out of a scrap wood plank, ten screws, five stripped copper wires, and of course the MakeyMakey creation kit. The guitar acts as an alternate controller to the traditional Guitar Hero guitar, which was played with five different-colored buttons.
We improved the design of this model by stretching the copper wires across the plank so they could be used in place of the buttons, to give the player an experience closer to playing an actual guitar.
There are five strings (which correspond to the five buttons) each labeled A, S, D, F, G. When each wire (string) is touched, it will play the dedicated note in response to the electrical current in our bodies being passed through the strings, to the screws, to the alligator clip and thus to the MakeyMakey board and attached computer.
