Description

The Water Organ is a capacitive Midi Controller. There are 24 inputs to which you can connect cups of water or other capacitive stuff like fruits or vegetables and touch them with your hands in order to make music.

The circuit uses two MPR121 breakout boards in order to make individual capacitive buttons. The button states will be sent over a Midi output. A Midi input can be used to control a neopixel strip, which also can be hooked up to the main connector. The brain is an Atmega328p.
