Re: Measuring motor speed

Ether: we get one count per rev with that magnet. I believe the student had the averaging set to 1, and period length set to 1s (need to double check the Counter class myself, see if we can get something shorter). I am anticipating doing bang-bang, and frankly, I don't know how fast we'll run it. One of the students put together a test program just for the shooter; when we implement speed control, we'll leave the provision to vary parameters in real-time and run some experiments. I am really hoping to do this Saturday, depends on whether or not our Hall-Effect goodies show up. I'm going to get someone coding tonight so we are ready for Saturday.

iambujo: be interesting to see if you get comparable results with your boards. What sensor did you use?
