The correct product thread for that motor is under Robotics / Mechanical -> Motors & Servos
Here is a direct link to get to it:
viewtopic.php?f=93&t=1323In the first post you will find an example sketch which shows how to correctly control it. It's simply a case of pulsing each of the 4 controllers pins in turn. The direction in which you pulse the pins determines the direction in which the motor turns. The Arduino stepper motor example will not work with that item as it was written for a different type of controller.
Just for future reference, if you have trouble finding the correct forum thread just use the forum search feature and do a search using the product code. Most of our items have a product thread associated with them but there may be one or two we have missed so if you still can't find the correct thread just post in the general discussion area. Nothing is off topic there
