There is a new Build Your Music hands-on lab, that allows participants to assemble Arduino components, connect them to a xylophone, and play a few simple songs. The intent of this lab is to give newcomers an opportunity to handle Arduino components for themselves, and to inspire them to create their own Arduino projects.
I will be including this lab as part of my exhibit at the Science Museum of Oklahoma Tinkerfest, Saturday, September 29.
For details and instructions on creating and demonstrating this lab for yourself, see the Music Lab Tutorial.
