Small project #1:
Cat toy w/ Servo motor:
This *kind of* worked. After I set it up the motor started to move back and forth, but erratically and jumping around a lot. The movements didn't seem to correspond directly to me turning the potentiometer to the left or right. I jazzed it up a bit with some arrows and patterns, and my cats were intrigued, but I still have some troubleshooting to do.
