Wiring Diagram

Up: OFF; Down: "ON"

Other Preparation Work

1. In this tutorial, we'll use a bipolar stepper motor, 1.8 step angle, 1.7A
2. Set current: 1.7A
3. Set Micro Step: 32
4. Connect a 9~42V DC power supply

int PUL=7; //define Pulse pin
int DIR=6; //define Direction pin
int ENA=5; //define Enable Pin
void setup() {
  pinMode (PUL, OUTPUT);
  pinMode (DIR, OUTPUT);
  pinMode (ENA, OUTPUT);

}

void loop() {
  for (int i=0; i<6400; i++)    //Forward 5000 steps
  {
    digitalWrite(DIR,LOW);
    digitalWrite(ENA,HIGH);
    digitalWrite(PUL,HIGH);
    delayMicroseconds(50);
    digitalWrite(PUL,LOW);
    delayMicroseconds(50);
  }
  for (int i=0; i<6400; i++)   //Backward 5000 steps
  {
    digitalWrite(DIR,HIGH);
    digitalWrite(ENA,HIGH);
    digitalWrite(PUL,HIGH);
    delayMicroseconds(50);
    digitalWrite(PUL,LOW);
    delayMicroseconds(50);
  }
}

Result

The stepper motor rotates 6400 steps (a cycle), and reverses 6400 steps (a cycle).

• When “EN” is Low, the motor is in a free states (Off-line mode). In this mode, you can adjust the motor shaft position manually; when “EN” is High (Vacant), the motor will be in an automatic control mode.
• "Direction" is the motor direction signal pin,
• "PULSE" is the motor pulse signal pin. Once the driver get a pulse, the motor move a step.
