what is pulse width modulation?

Pulse width modulation means a signal that changes Pulses with a time interval called Pulse width modulation (PWM).PWM signal is a digital signal change with the ms time delay.in servo motor, PWM signal changes the cycle every 20ms with the pulses change between sequence of 1ms to 2ms. the PWM signal change duty cycle of 1.5 ms of the 50-60hz frequency cycles approx of 5-15% range of duty cycle of 50-60hz

servo motor movement is changed with the change of coil current cycles change with the time. the speed of the servo runs faster when the pulse frequency is more. the delay means the no. of pulses, speed means the frequency of motor .so never be confused about pulse and speed frequency

servo motor

Duty cycle

Duty cycles mean no. of signal change with time intervals

How stepper motor phase or duty cycles change

PWM APPLICATION

• electronics microcontroller to speed applications like led switching, blinking, scrolling, camera shuttering, buzzer etc.
• Servo, Stepper, BLDC motors controlling.
• data shif register in electronics
• signal generator
• medical equipment
• amplifier
• Telecommunication

Servo Motor Control Arduino Code

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
}
