Servo motor, what's inside

The video tutorial explains the components and functioning of a servo motor system. It covers the electrical connections, gear train setup, and the role of the circuit board and potentiometer. The tutorial details how pulse width modulation (PWM) signals control the servo's position and the feedback mechanism involving a potentiometer and comparator. The video also demonstrates how to use an Arduino or servo tester to control the servo motor.

What happens when the width of the pulse sent to the servo motor is changed?
