this final project is a MIDI music instrument Key board. The concept of my project is to use the lowest cost to create a music instrument. this project have a more personal meaning for myself. I want to combine the  technology and the cheap material. This project is to remind me lack of instrument is not the reason to blame on if I don’t learn.  It depend on myself to learn something.

Material: Adafruit circuit playground express(CPX), Copper tape, alligator clip, foam cardboard. MIDI receive  software (EX.Gargeband)

First, we need to find the code for MIDI transformation and input to CPX

cut a decent rectangle size foam cardboard

 

put copper tape on foam cardboard

connect the foam cardboard and the CPX

test on different instrument with different MIDI signal in each code

solder the wire to the foam board

solder the wire to the CPX
