Tutorial: Stepper Motor + Easy Driver + Arduino

The Arduino board can be used for many applications, including driving DC motors, servos and Stepper Motors. A Stepper Motor is a kind of electric motor that can be used when we need perfect angular position.

On this tutorial, we will show how use an Arduino board to control a Stepper Motor. To control this motor, we need an H bridge or a control board, like the Easy Driver.

Put everyting together like the picture:

 

Now connect the Power Supply 1 to a 7V to 30V, 1A power supply.

Open the Arduino IDE and paste the code:

int dir = LOW;
int stepp = LOW;
long previousMillis = 0;
long currentMillis = millis();
long steptime = 500;
int x = 0;
char c = 0;

void setup()
{
  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  Serial.begin(9600);
}

void loop()
{
  if(Serial.available()>0)
  {
    c=Serial.read();
    if(c=='a')
    {
      dir = HIGH;
    }
    if(c=='z')
    {
      dir = LOW;
    }
  }
  if(currentMillis - previousMillis > steptime)
  {
    previousMillis = currentMillis;
    if(stepp==LOW)
    {
      stepp = HIGH;
    }
    else
    {
      stepp = LOW;
    }
    digitalWrite(2,dir);
    digitalWrite(3,stepp);
  }
}

Upload the code and open the Serial Monitor.

In the Serial Monitor, type 'a' and press Enter. The motor will rotate to one side. Then type 'z' and the motor will rotate backwards.

Great tutorial.  Simple and to the point.  One suggestion:  for beginners, you may want to include some comments in the code so that they can better understand the purpose of each part of the code.  Thanks for posting.

i want to make invention using arduino,, but the problem is,, there is no arduino here in my country,, can any tell me where i can buy that item...

E-bay has many Arduino clones, Amazon has Original Arduino Uno R3 Uno R3 for $21.95 (as of 6/6/12)

Or you can make your own Hackduino

Hi there, ive been woking on this tutorial and it is exactly what i need, with use of the serial monitor. However i am using a big easy driver instead, but the code wont work.... Do i need to change any of the code for this, or the board set up ? I have imitated the setup exactly as above but it wouldnt work, however i'm not sure about the enable to second ground? Is this needed, i have tried with and without but no luck.
