"WebHow It Works. The shaft of the potentiometer is rotatable from 0° (nearest by GND) to an upper bound angle (nearest by VCC pin), called ANGLE_MAX. The voltage at the output pin ranges from GND 's voltage to VCC 's voltage. The output voltage is in direct proportion to the rotated angle of the shaft. If the angle is 0°, output pin'S voltage is 0v. " - How to set up potometer
