“HKU Assignment
Welcome to my “If This Then That” Project.
For this project I made a simple music box where you can play several chords of instruments. You can choose which instrument you want to play (piano/guitar) and which chord you want to play per button.
In this instructable I will show you my concept, iterations and a short reflection. I will also share an electronic scheme and the code with explanation.
