Demo for ProtoStax Capacitive Touch Piano and ProtoStax Multi-Octave Capacitive Touch Piano
with Adafruit 12 x Capacitive Touch Shield for Arduino - MPR121, Piezo Buzzer, Arduino
using ProtoStax for Arduino Enclosure
This demo uses
- Adafruit 12 x Capacitive Touch Shield for Arduino - MPR121
- Piezo Buzzer - PS1240
- ProtoStax for Arduino
- Arduino (Uno), but you can use other form factors that fit a Shield
The multi-octave piano also uses 2 momentary push button switches to move the octave of the piano up or down from the base octave, giving multi-octaves with the same capacitive touch keyboard.
For further instructions, see the Portable Capacitive Touch Piano Tutorial at Hackster.io
Also see Multi-Octave Portable Capacitive Touch Piano Tutorial
This demo uses:
- Adafruit_MPR121 library v 1.1.3 - see https://github.com/adafruit/Adafruit_MPR121
- JC_Button library v 2.1.5 - see https://github.com/JChristensen/JC_Button
It also uses the built-in tone library. You can replace it with the NewTone library if you like
Arduino IDE->Sketch->Include LIbrary->Manage Libraries - choose
