Working Of Servo Motor In Arduino Mega 2560

Introduction

This article I will explain about the working of servo moter. It will work according to the rotating method and the system can be used for door locking purposes.

Parts

• Servo
• Arduino Mega 2560
• HookUp Wires

Servo

Figure 1: Servo

• It is small and cost effective.
• It is used for small robotics and radio controls.

Connection 

• The servo first pin can be connected to the Gnd
• The second pin can be connected to the Vcc
• The Third pin can be connected to the digital pin 09 of the Arduino Mega 2560.

Programming

#include <Servo.h>
Servo myservo;  // create servo object to control a servo
void setup()
{
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}
void loop(){
  myservo.write(0);     // sets the servo at 0 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(90);    // sets the servo at 90 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(180);   // sets the servo at 180 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(90);    // sets the servo at 90 degree position
  delay(1000);          // waits for the servo to get there
}

Explanation

• The servo can work in the condition of the degree.
• It can first rotate in the 0 degree
• Then 90, 180, and it will automatically return to 90 degree.
