Rotation sensors?

[Alan Anderson]

A potentiometer has three connections. They all go to an input on the Analog Breakout. Using a standard PWM extension cable, the black wire (ground) goes to one end of the pot, the red wire (+5 volts) goes to the other end, and the white wire (signal) goes to the pot's wiper.

[Al Skierkiewicz]

In general, single turn pots have ~270 degrees of rotation. Don't depend on all of them having this specification. Check the data to be sure and then expect something less. Never use the entire 270 degrees.
