BINARY IO is an Arduino-powered, four-button MIDI controller
Developed as part of a semester project, BINARY IO is a nifty little MIDI controller capable of counting from one to 15 using only four buttons. The device, which uses binary code as an input mechanism, is powered by an Arduino Uno and Max/MSP.
With a little practice, BINARY IO becomes quite intuitive and fun to play. As demonstrated by its creators Benjamin Weber and Jeremy Ondrey, users can piece together new music with sounds ranging from the piano to the xylophone to the drums.
