For the Makey Makey Audio Player sketch, I made an interface that plays a guitar strumming. The symbol in the middle, and all the ones on the right determine the note that the guitar will strum, and they are labeled as such. The lightning bolt labeled “speed”, changes the speed of the strumming. The “Play” feature pauses and plays the strumming. Gate is where I hooked up the ground cable, and it is basically a lock you need to press to use the features described.
