Lets try to make a Electronic Concertina
So we need some pushbuttons … at least 14 .. for the most simple tunes.
A sensor for push and pull.
A buzzer or better yet .. a jack for earphones.
Arduino with enough pins to connect a keyboard matrix.
When using a keyboard matrix only single keypresses are detected.
So we cant do chords!
