SERVO MOTOR INTERFACE USING ARDUINO 

  SERVO MOTOR INTERFACE USING ARDUINO 

 

 

📡SERVO MOTOR Interface with Arduino – Short Note

Overview:

A servo motor is a precise motor used in robotics, automation, and control systems. It rotates to a specific angle based on the input signal. Arduino can control a servo motor using PWM (Pulse Width Modulation) signals.

🔌 Wiring:

  • Servo Motor has 3 wires:

    • Red → Vcc (usually 5V)

    • Brown/Black → GND

    • Orange/Yellow → Signal (connect to Arduino PWM pin like D9)

🔌 Circuit Diagram:

 

 

📝 Sample Arduino Code:

#include <Servo.h> // Include the Servo library

Servo myServo; // Create a Servo object to control a servo
int pos = 0; // Variable to store the servo position

void setup() {
myServo.attach(4); // Attach the servo signal wire to pin 4
}

void loop() {
// Sweep from 0 to 180 degrees
for (pos = 0; pos <= 180; pos++) {
myServo.write(pos); // Set servo to current position
delay(15); // Wait 15 milliseconds for the servo to move
}

// Sweep back from 180 to 0 degrees
for (pos = 180; pos >= 0; pos–) {
myServo.write(pos); // Set servo to current position
delay(15); // Wait 15 milliseconds for the servo to move
}
}

🔧 Applications of Servo Motor with Arduino:

  1. Robotics 🤖

    • Used for joint movement in robot arms and walking robots.

  2. Automated Door Systems 🚪

    • Controls the opening and closing of doors based on sensors (e.g., IR, ultrasonic).

  3. RC (Remote-Controlled) Vehicles 🚗

    • Used to steer wheels or control flaps in RC cars, planes, and boats.

  4. Camera Gimbals / Pan-Tilt Systems 📷

    • Helps rotate or tilt a camera for surveillance or photography.

  5. Smart Home Projects 🏠

    • Used for window blinds, curtain movement, and smart locks.

  6. 3D Printers and CNC Machines 🖨️

    • Controls precise position of tools or nozzles.

  7. Solar Trackers ☀️

    • Moves solar panels to follow the sun for maximum energy absorption.
