Short example on how to control a stepper motor

Stepper Motor

int M1dirpin = 4;
int M1steppin = 5;

void setup()
{
  pinMode(M1dirpin,OUTPUT);
  pinMode(M1steppin,OUTPUT);
  digitalWrite(M1dirpin,LOW);
}

void loop()
{
  delay(3000);
  step(50, 1000);
}


// Where steps is total amount of steps taken
// and time is the total amount of time in microseconds
// the steps should take to complete
void step(int steps, int time){
  int delayTime = time/steps;
  
  for(int i=0; i<steps; i++){
    digitalWrite(M1steppin, LOW);
    delayMicroseconds(2);
    digitalWrite(M1steppin, HIGH);
    delay(delayTime);
  }
}
