How it works: First, load up a computer program or any webpage, let’s say you choose the piano.
Then, instead of using the computer keyboard buttons to play the piano, you can hook up the MaKey MaKey to something fun, like bananas, and the bananas become your piano keys.
The invention kit comes ready to use out of the box: MaKey MaKey, Alligator Clips, USB Cable.
