Why example code: stepper_oneReveution (28BYJ48+ULN2003) turns only clockwise?

What could be the reason(s) that my stepper 28BYJ48 (with UNL2003) is turning only clockwice with the example code stepper_oneRevolution?

2

Does it make any noises/vibrations during the time it is supposed to be going the other way?

My best guess is that it's wired incorrectly.

Take a good look at this -> http://arduino-info.wikispaces.com/SmallSteppers

Thanks!

The wires 2 and 3 were wrong.

Now it is working as it should.
