Servo motor control with Servo library in Arduino - Mini Project: Build & Apply

Servo motor control with Servo library

📖 Scenario: You have a small robot arm that uses a servo motor to move. You want to control the servo motor angle using Arduino and the Servo library.

🎯 Goal: Build a simple Arduino program that moves a servo motor to a specific angle using the Servo library.

📋 What You'll Learn

Include the Servo library

Create a Servo object named myServo

Attach the servo to pin 9

Set the servo angle to 90 degrees

Print the servo angle to the Serial Monitor

💡 Why This Matters

🌍 Real World

Servo motors are used in robots, remote-controlled cars, and camera gimbals to control precise movements.

💼 Career

Understanding servo control is important for jobs in robotics, automation, and embedded systems development.

1

Include Servo library and create Servo object

Write #include <Servo.h> at the top and create a Servo object called myServo.

Arduino

#include 
// Your code here

Hint

Use #include <Servo.h> to include the library and Servo myServo; to create the servo object.

2

Attach servo to pin 9

In the setup() function, attach myServo to pin 9 using myServo.attach(9);.

Arduino

#include 
Servo myServo;

void setup() {
  // Your code here
}

void loop() {
}

Hint

Use myServo.attach(9); inside setup() to connect the servo to pin 9.

3

Set servo angle to 90 degrees

In the setup() function, after attaching the servo, set the servo angle to 90 degrees using myServo.write(90);.

Arduino

#include 
Servo myServo;

void setup() {
  myServo.attach(9);
  // Set servo angle to 90 degrees
  // Your code here
}

void loop() {
}

Hint

Use myServo.write(90); to move the servo to 90 degrees.

4

Print servo angle to Serial Monitor

In setup(), start serial communication with Serial.begin(9600); and print the text "Servo angle: 90" using Serial.println().

Arduino

#include 
Servo myServo;

void setup() {
  myServo.attach(9);
  myServo.write(90);
  // Start serial and print servo angle
  // Your code here
}

void loop() {
}

Hint

Use Serial.begin(9600); to start serial and Serial.println("Servo angle: 90"); to print the angle.
