Making Drawdio

This week the electronics team made something called the Drawdio. A Drawdio is a Pencil that has a circuit board that we build and add it on to the pencil. What the circuit board does it has a Circuit board, 2 capacitors, 2 resistors, transitors, ceramic capacitor, a chip that has a timer, speaker, thumbtack, wire, copper foil, and a pencil. So what the drawdio does it makes music/ sound with using graphite to have enough energy to make sound which we use to make music.
