![]() ![]() That means the control signal pulse should be applied to the PWM pin every 20ms duration. The frequency of the PWM signal should be 50Hz. To control rotation, we apply pulses to the PWM pin of the servo motor. The position of the servo rotator is directly related with the width pulse applied to the PWM signal of the motor. How to control Servo motor rotator movement? You just have to call a function used in servo.h library and its as simple as that. So you don’t need to write lengthy code for servo motor. Fortunately Arduino IDE already has a built-in library (servo.h ) for servo motor control. We can calculate the servo motor’s position by varying the duration of pulses to servo with the help of Arduino Uno R3. A pulse of duration 1 millisecond causes the servo motor to move one end and duration of 2 millisecond causes the motor to move other end. However, the main disadvantage of servo motor is its lower speed and low power limitation as compared to other motors.Ī servo motor responds to changes in duration of pulses. So the main advantage of servo motor is that it doesn’t require any interfacing circuit. H bridge is used to rotate motor either in clock wise or anti clock wise direction. Servo motor can not move with continuous motion unless feedback potentiometer is connected.
