This semester I’m taking a course about Arduino microcontrollers. One of the things included in the materials we got was a servo, and the first thing I did on the first day was looking up how servos worked. I didn’t know there was a servo library for the Arduino, so I ended up writing my own program to change the duration of the pulse sent to the servo based on some serial input (which I also had to look up, since we hadn’t learned it yet). I thought it was really neat and I ended up just playing around with it a lot.
Here’s some videos from earlier:
