Sparkfun Electronics Rotary Potentiometer - 10k Ohm

The Rotary Potentiometer - 10k Ohm can open up many interesting user interfaces. 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. Able to open up many interesting user interfaces; Just turn the pot and the resistance changes; Center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot
