Serial Lab #1 (crunchy!)
I like working with serial from Arduino to Processing. It makes me a little giddy.
These are the sensors I hooked up, and below that are the different kind of designs I could make using the standard Processing code.
I first tried FSR’s and didn’t really notice a difference between them. Pretty plain spikes and dips depending on pressure. I tried to take out as much upswing and downswing in the signal, shown below, which almost looks like a momentary switch. Oops.. that is the momentary switch. Documentation fail.
I ripped a tiny microphone out of a broken audio tape walkman and stuck it in the breadboard to see if I could get sound to make spikes appear on the graph. It wasn’t that sensitive to sound, but it was sensitive to hard wind blowing on it. Not very precise, but also not set up for precision. Something worth looking into.
