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
