Radio Control (RC) Servo Motor with PWM – Video Tutorial
This video tutorial is about servo motor that controlled by PWM signal. There should be two electrical input, one for the power and another for the control signal (to command a position). This servo motor is very common that can be found in the radio control cars and airplanes. The position of the servo motor is related with the width of the pulse of control signal. To move the rotor to a certain angle, we must change the frequency so the pulse width is proportional with that angle. Here is the video :
