An adjustable potentiometer, 1M 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. A potentiometer is Pre-mounted and 3 output berg connector pin are available for easy connections and disconnections in your project.
