Piano Cabinet for DIY

Piano. This was one of my projects thats focus was on 3D-modeling. The Documentation and Models may be not the best. But if you dont want to make a Micro Piano case from ground up you do now have a great basis or even a complete kit. What you need :

-MCU(Arduino Board)

-Breadboard

-12 small Buttons

-Baterie and the connection of it for power suply

-aktive buzzer

-jumper wires

-Schematic= isn´t that hard just try some things out

-code (IDE_Arduino UNO)

/* because of the limited inbuts on my board are here just 11 functioning Keys.

i know that the code is terible but it works XD
