Led Piano – Switches and LED Circuits Physical Computing

For this week assignment, we had to make an application using switches and LED analog circuits. I wanted to make an object that reacts to more than one input so I came up with the idea to create a LED Piano prototype. Doing this project I learned how to use the Arduino to power my piano and also to set up a circuit in the breadboard. The switches close the circuit when the key is pressed connecting the wire and aluminum foil that is attached to the key together with the wire that is in the bottom surface of the piano.
