Virtual IoT Lab DEI – Servo Motor

Instructions

Objective:

Learn how to control a servo motor using Arduino to create precise angular movements between 0 and 180 degrees.

Steps to Perform:

In the Arduino code, modify the angle value on line 1 (0–180)
Click "Run Code" to start the simulation
The servo motor will sweep from 0° to your specified angle and back continuously
You can change the angle value and click "Run Code" again to update
Click "Stop" to halt the servo at any time
Valid range: 0° (far left) to 180° (far right)

Key Concepts:

Servo Motor: Motor that can rotate to precise angles (0–180°)
Servo Library: Arduino library for easy servo control with Servo.h
Pin 11: Digital pin connected to servo control signal wire
servo.attach(): Connects servo object to specified pin in setup()
servo.write(angle): Positions servo to specified angle in degrees
Angle Control: Change the angle parameter (0–180) to control position
Real-time Control: Run your code to instantly see servo movement

Arduino Code — main.ino

          int angle = 90;

#include <Servo.h>

int servoPin = 11;
int pos = 0;
Servo servo;

void setup()
{
  servo.attach(servoPin);
}

void loop()
{
  for(pos = 0; pos <= angle; pos++)
  {
    servo.write(pos);
    delay(15);
  }
  for(pos = angle; pos >= 0; pos--)
  {
    servo.write(pos);
    delay(15);
  }
}
