How to Interface Servo Motor with Arduino - Ryzen Hunt

Interfacing Servo Motor with Arduino

    Hello Earthians, in my previous posts , I have explained some basic tutorials of Arduino. In this post, I will explain, how you can interface servo motor with Arduino. Here we would know, what are servos and how can we control them using Arduino.

If you don't know what is Arduino and how to program an Arduino, please check my previous post, mentioned below:

What is Servo Motor?

    A servo motor is a rotary actuator that allows precise control of angular position, acceleration, and velocity. A servo motor works as a closed-loop system providing torque and velocity as commanded by a controller.

Servo motors have gears that help them to move precisely. These servo motors are mainly used at linear and angular positions to get specific acceleration and velocity.

Here I would be using Arduino as a servo controller but you can use any type of Arduino.

Circuit Diagram:

In the circuit, we have connected the GND and powerPin to GND and 5V respectively in the Arduino and the signalPin is connected to the PWM pin 5. Now let's go for the coding part.

Source Code:

//This code is written by Anikesh at RyzenHunt #include <Servo.h> Servo servo; // variable servo as Servo to library int i; //this variable is used for iteration void setup() { servo.attach(5); //attaching the servo to pin 5 } void loop() { // scan from 0 to 180 degrees for(i = 0; i < 180; i++) { servo.write(i); //moving the servo delay(10); } // now scan back from 180 to 0 degrees for(i = 180; i > 0; i--) { servo.write(i); //moving the servo delay(10); } }

Result:

After successfully uploading the source code to the Arduino Board, we find that our Servo Motor starts moving/sweeping. In case, if it doesn't work, please write in the comment box or contact me.
