The 64 Button Shield not only allows you to use up to 64 buttons with your next Arduino project, it also has a hidden “easter egg” that allows it to output MIDI. This video demonstrates MIDI functionality by using a 64 Button Shield, a Midivox, and an Arduino together for use as a physical interface for your favorite MIDI compatible music program. Want to build one? The Maker Shed has everything you need (except the arcade buttons.) Also, looking for a great deal?
