Servo on Arduino Mega 2560

This post describes how to connect a 5V Servo to an Arduino Mega 2560.

The Servo needs GND, 5V and a data line. The Arduino Mega 2560, once powered via a USB Cable, is able to provide these three signals to the servo.

You can use three male to male jumper wires to connect the servo to the Arduino Mega 2560. Connect the data line to pin 9 on the Arduino Mega 2560 so it directly matches the Sketch outlined below.

As a sketch, the example sketch found under File > Examples > Servo > Sweep worked perfectly. It turns the servo to either ends of it’s 180 degree range.

  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
  }
