I hope someone is familiar with rotation sensors, I was looking at this one http://www.robotshop.com/ProductInfo.aspx?pc=RB-Dfr-43
I wanted to know how the connections consisted of, I guess the metallic shaft needs to be moved by something else? And do you need any other components to set it up with breadboard?
And how would this one work? this is an encoder based one http://www.robotshop.com/phidgets-rotation-sensor.html
I want to use this with a dc motor. Any ideas would be helpful, as I do not have any background in sensors whatsoever.
