Re: Optical Sensors Used as Encoders?

We tested the banner sensors to measure RPM's, and from what I saw it worked quite well, but our team decided to go with shaft encoders.

We also were going to use a potentiometer to measure the position of our arm, but also went with shaft encoders for that since the potentiometers from RadioShack were only responsive over about 180 degrees of their range, and we needed the full 270 degrees. We could have geared down the potentiometer, or gone with higher quality potentiometer, but we already had the shaft encoders.
