DIY Scratch I/O Board Using Arduino

I downloaded Scratch to play with it after a presentation on E-Textiles at UPenn back in April. I found it kind of interesting, and I was particularly interested in the “Scratch Sensor Board“, which provides a way to send physical signals into Scratch scripts and have Scratch respond to them. It’s a pretty simple protocol, and I filed away “build a Scratch sensor board” as one of those projects that I might do … someday. Well, nothing like being stuck at home during a major weather event to crank up the boredom level to the point that ya gotta do something. So, courtesy of Hurricane Irene, here’s a DIY Scratch Sensor written as an Arduino Sketch.
