This is what you get when you add a whammy bar to a piano.
Created by Maker Gonçalo Silva, the littleBits Waving Piano is an ATmega32U4 based keyboard that was programmed to behave as an oscillator.
How it works is relatively simple: As keys are pressed on the board, they are read by the Arduino module and mapped to the corresponding pitch, as you would hear on a real piano. Meanwhile, the slide is used to “wave” the output pitch just like a guitar’s whammy bar.
