Arduino Library

Library Installation

  1. Open Arduino IDE → Sketch → Include Library → Manage Libraries.
  2. Search for Adafruit Motor Shield.
  3. Click Install.

Example Arduino Code (DC Motor)


#include "AFMotor.h"

AF_DCMotor motor(1);  // Motor connected to M1

void setup() {
  motor.setSpeed(200);   // Speed range: 0 - 255
  motor.run(RELEASE);    // Ensure motor is stopped
}

void loop() {
  motor.run(FORWARD);
  delay(2000);

  motor.run(BACKWARD);
  delay(2000);

  motor.run(RELEASE);
  delay(1000);
}

Example Arduino Code (Stepper Motor)


#include "AFMotor.h"

AF_Stepper stepper(200, 2);  // 200 steps per revolution, connected to M3/M4

void setup() {
  stepper.setSpeed(60);  // RPM
}

void loop() {
  stepper.step(100, FORWARD, SINGLE);
  delay(500);

  stepper.step(100, BACKWARD, SINGLE);
  delay(500);
}

Power Notes

  • Always use an external power supply for motors.
  • Match supply voltage with motor ratings.
  • Avoid powering motors from Arduino 5V.
  • Verify polarity before applying power.

Applications

  • Robotics projects
  • Motor control experiments
  • Automation systems
  • DIY embedded projects

Tips & Information

  • Motors may generate electrical noise — decoupling capacitors are recommended.
  • Provide sufficient ventilation under heavy load.
  • Do not exceed continuous current ratings.
  • Suitable for small to medium-sized motors.
