This week we worked with analog out, using it to control a servo motor and a small speaker. To create sound, we used the tone function and the pitches library.
I used a photocell as my variable resistor for servo motor control, but I also tried building my own FSR with velostat. I got normal readings before sewing everything together (with resistance varying depending on how close the probes are to one another) but then got really wild unpredictable readings when I tested it after.
I didn’t end up connecting it to my circuit because I wasn’t sure what value resistor to use. I wonder what happened?
