5. Piano

Use the music module and the mPython Board touchpad to make a simple 7-scale touch piano.

import music                        # miport music module

pStatus,yStatus,tStatus,hStatus,oStatus,nStatus,p0Status=[1]*7  # Key status flag variable

p0 = TouchPad(Pin(33))              # As only 6 touchpads on the mPython Board, one more is required, expand pin P0, corresponding to IO33 of ESP32
