Got a new oscilloscope. Was trying to think of what I could do with it as a first project. Remembered teaching my kids about PWM LED dimming on the Arduino a couple of years back, so I made this video: LED Dimming: PWM vs Current - YouTube
I was using a brushless Gopro gimbal, but the video is still a little shaky at times. Sorry, guess I need a second tripod. The equipment list never ends.
Anyway, hope someone finds this useful or interesting.
