Coda

Coda is a wireless instrument that is capable of playing an octave of notes ranging from C7-C8 on a piano. The Arduino device uses an IR remote as an input which sends button press signals to an IR receiver. The receiver processes the data, and outputs appropriate noises on the buzzer, and tells the user what note is playing on an LCD screen.
