Hi, i have found that I have the same board and stepper, so I set it up, it did work, but there was no direction change.
Try this sketch, that I found ages ago and moded so that it runs without a speed pot.
Used pins 2,3,4,5 and see what happens, this stepper is 5V and I am able to run it off the arduino 5V.
/*
Stepper Motor Control - speed control
This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 2 - 5 of the Arduino.
A potentiometer is connected to analog input 0.
The motor will rotate in a clockwise direction. The higher the potentiometer value,
the faster the motor speed. Because setSpeed() sets the delay between steps.

}
val is set to 1000, the lower the value the slower the speed, so you can see the stepper control strobe.
Hope it helps.
