Step motor with button

I'm only using a step motor, the arduino and the button plug in arduino

bunogenrinho:
It means that the button has 2 wires and one is at pin 2 and the other is connected at GND

Then your code is wrong, since when the button is pressed digitalRead() will return LOW, not HIGH.

Just declare the pin mode thus:

 pinMode(buttonPin, INPUT_PULLUP);

and change your button press logic to:

 // check if the pushbutton is pressed. If it is, the buttonState is LOW:
 if (! buttonState)  // use negation operator, much less cumbersome

Using the internal pullups like this is possible only if the button switches to ground.
