Our first Scratch and Sound workshop. We introduced the idea of circuits and computer inputs and outputs then we broke out the makeymakey and demonstrated a few of these ideas. We first wired up some bananas and then demonstrated how current can pass through the whole group pulling the switch to ground.
We then constructed a banana piano and had a look at how the piano software works in SCRATCH 2. Finally we made some pressure pad switches with cardboard and tinfoil and taped them to the floor to create a giant keyboard.. then we stomped on the keys.
