SparkFun Rotary Potentiometer - Linear (10k ohm) General Hardware a comparator that amplifies theAn adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user! This is a center tap linear type potentiometer. The outer two pins will always show 10K resistance,
