To control Servo Motor using Arduino, read the steps below:

To control a Servo Motor using an Arduino, follow this experiment with the steps outlined below. This experiment demonstrates how to connect a Servo motor to an Arduino, and provides example code for you to incorporate Servo motor control into your projects.

Components Required:

Arduino Uno with USB 2.0 Cable
Servo Motor
Jumper Wires

Arduino Uno with USB 2.0 Cable:

Arduino is an open-source electronics platform that combines user-friendly hardware and software, catering to individuals involved in creating interactive projects.

Servo Motor :

The operation of servo motors involves the transmission of an electrical pulse width modulation (PWM) through the control wire. This system consists of a minimum pulse, a maximum pulse, and a repetition rate. Servo motors have the ability to rotate approximately 180 degrees, with 90 degrees available in each direction.

Wire Description:

RED – Positive (VCC)
Brown – Negative (GND)
Orange – Signal (PWM)

Specifications:

Operating Voltage is +5V typically
Torque: 1.2kg/cm
Operating speed is 0.1s/60°
Rotation : 0°-180°
Weight of motor : 9gm

Jumper Wires:

A jumper wire is an electrical wire equipped with a connector or pin at each end. Typically used in electronics, it serves to interconnect components without the need for soldering, providing a convenient and flexible means of establishing electrical connections.

A jump wire is an electrical wire with a connector or pin at each end, which is normally used to interconnect the components each other without soldering.

Connection Diagram:

Establish connections between your components according to the diagram, and link the USB cable from the Arduino to your computer.

The power wire is red, and should be connected to the 5V pin on the Arduino board.
The ground wire is - black or brown and should be connected to a ground pin on the board.
The signal pin is - yellow or orange and should be connected to pin 9 on the board.

Connect your components as shown in diagram and connect USB cable to Arduino to your computer. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. The ground wire is typically black or brown and should be connected to a ground pin on the board. The signal pin is typically yellow or orange should be connected to pin 9 on the board.

Adding the Servo.h library:

In this tutorial important to add library to your Arduino IDE. Servo library is inbuilt library. If you want to add Servo.h to Arduino sketch follow below steps.

In the Arduino IDE, go to Sketch >> Include Library >> Add Servo library.

Servo library is inbuilt library. If you want to add Servo.h to Arduino sketch follow below steps. In the Arduino IDE, go to Sketch >> Include Library >> Add Servo library.

Arduino Code:

#include <Servo.h>

Servo myservo; // create servo object to control a servo

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() {

// goes from 0 degrees to 180 degrees

for (pos = 0; pos <= 180; pos += 1) {

// 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

}

// goes from 180 degrees to 0 degrees

for (pos = 180; pos >= 0; pos -= 1) {

myservo.write(pos); // tell servo to go to position in variable 'pos'

delay(15); // waits 15ms for the servo to reach the position

}

Upload:

Connect Arduino board to computer using USB cable and wait for few seconds then it will show you "Com port".

Check your Com Port and Board Selection before upload Arduino code.
