Arduino - Motor Paso a Paso Bipolar

Motor Paso a Paso Bipolar

Codigo ejemplo:

 int Pin0 = 8;

 int Pin1 = 9;

 int Pin2 = 10;

 int Pin3 = 11;

 int _step = 0;

 int pases=0;

 boolean dir = false;// change the direction of the motor

 void setup()

 {

  pinMode(Pin0, OUTPUT); 

  pinMode(Pin1, OUTPUT); 

  pinMode(Pin2, OUTPUT); 

  pinMode(Pin3, OUTPUT); 

  Serial.begin(9600);

 }

   void loop()

 {

   for(pases=0;pases<4075;pases++){

     pas();

     delay(1);  // change this delay to control the speed of your stepper, delay to 100 you can see the signal LEDs blinking.

   }

   delay(500);

 }

 void pas()

 {

   switch(_step){

    case 0:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, HIGH);

    break; 

    case 1:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, HIGH);

      digitalWrite(Pin3, HIGH);

    break; 

    case 2:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, HIGH);

      digitalWrite(Pin3, LOW);

    break; 

    case 3:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, HIGH);

      digitalWrite(Pin2, HIGH);

      digitalWrite(Pin3, LOW);

    break; 

    case 4:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, HIGH);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, LOW);

    break; 

    case 5:

      digitalWrite(Pin0, HIGH); 

      digitalWrite(Pin1, HIGH);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, LOW);

    break; 

      case 6:

      digitalWrite(Pin0, HIGH); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, LOW);

    break; 

    case 7:

      digitalWrite(Pin0, HIGH); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, HIGH);

    break; 

    default:

      digitalWrite(Pin0, LOW); 

      digitalWrite(Pin1, LOW);

      digitalWrite(Pin2, LOW);

      digitalWrite(Pin3, LOW);

    break; 

  }

  if(dir){     _step++; ;  }else{     _step--;   }

  if(_step>7){     _step=0;   }

  if(_step<0){     _step=7;   }
