Check out this cool MaKey-MaKey PicoBoard Scratch Trumpet from Josh Burker:
I have been working on programming an electronic trumpet in Scratch. I am using a MaKey MaKey and a PicoBoard for the hardware side of this project. Here is the Scratch code I devised. You can download the project from my Scratch projects page.
Scratch reads the PicoBoard’s sound sensor to determine if I am blowing on the microphone. For some notes, which use all open valves on the trumpet, I have added a fourth key that the MaKey MaKey reads. Additionally, the PicoBoard reads how hard I am blowing on the microphone, so Scratch will play a low B flat, an F, or a high B flat.
