The difference between the original "Arduino Tinfoil Piano" is I make it looks better and add ione more key fo rthe paino.
Cut the Cardboard and Tinfoil Into Pieces
I used a 3D cardboard into 24cmx15cm, and the height is 4cm.
Cut 18 pieces of Tinfoil that the size is 11cmx2.6cm.
Step 2: Make the Piano Key
To make the piano key, you should cut all the tinfoil before you do this step. After you finish that step, take a small piece of double sided tape and stick it on one piece of the 11cmx2.6 cm tinfoil, then cover another piece of tinfoil on it.
