- An adjustable potentiometer can open many interesting user interfaces.
- Turn the pot and the resistance changes.
- Connect to one outer VCC pin, GND to the other, and the center pin will have a voltage that varies between 0 and VCC depending on the rotation of the pot.
- Hook up the center pin to an ADC on a microcontroller and get a user input variable
- This pot has a 1/4″ mounting diameter.
