Story

Control your projects with precision using the NEMA 17 Bipolar Stepper Motor and the L293D Motor Driver Shield. Follow our guide for detailed instructions and unlock the potential of your projects.

Wiring Diagram

1. Power Supply: to USB cable 5V output on the Arduino.

2. Motor Connections: Connect the stepper motor’s wires to the L293D’s motor channels:

Blue wire to M3(OUT1)
Black wire to M3(OUT2)
Green wire to M4(OUT3)
Red wire to M4(OUT4)

3. Motor Channels: Ensure the motor channels M3 and M4 on the shield are correctly wired to control the stepper motor.

Demonstration

Code

Code

#include <AFMotor.h>

// Create the motor object using the Adafruit Motor Shield library
AF_Stepper motor(200, 1);  // 200 steps per revolution, connected to motor port 2 (M3 and M4)

void setup() {
  Serial.begin(9600);  // Start serial communication
  motor.setSpeed(60);  // Set the speed to 60 RPM
}

void loop() {
  Serial.println("Clockwise");
  motor.step(200, FORWARD, SINGLE);  // Move 200 steps clockwise
  delay(500);
  
  Serial.println("Counterclockwise");
  motor.step(200, BACKWARD, SINGLE);  // Move 200 steps counterclockwise
  delay(500);
}
