Control 2 or more Servo with Potentiometers using Arduino

Control 2 or more Servo with Potentiometers using Arduino

This this video shows how to control 2 or more Servo motors with Potentiometer. We will use separate potentiometer for each servomotor. When rotating potentiometer, the servo will move from 0 to 180 degrees.
