Example Arduino Code:

// Define control pins
#define IN1 8
#define IN2 9
#define IN3 10
#define IN4 11
#define ENA 5
#define ENB 6

void setup() {
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(IN3, OUTPUT);
  pinMode(IN4, OUTPUT);
  pinMode(ENA, OUTPUT);
  pinMode(ENB, OUTPUT);

  digitalWrite(ENA, HIGH); // Enable Motor A
  digitalWrite(ENB, HIGH); // Enable Motor B
}

void loop() {
  // Rotate clockwise
  stepMotor(1);
  delay(1000);

  // Rotate counterclockwise
  stepMotor(2);
  delay(1000);
}

void stepMotor(int direction) {
  if (direction == 1) {
    digitalWrite(IN1, HIGH);
    digitalWrite(IN2, LOW);
    digitalWrite(IN3, HIGH);
    digitalWrite(IN4, LOW);
  } else if (direction == 2) {
    digitalWrite(IN1, LOW);
    digitalWrite(IN2, HIGH);
    digitalWrite(IN3, LOW);
    digitalWrite(IN4, HIGH);
  }
}
