I was hoping that someone could help explain how I should hookup this motor/controller. I was also hoping for a simple code sample on how I would simply rotate and then reverse rotation.
I am sorry for asking. I have been looking for several days and just don't quite understand how to get this working.
You don't mention what you are using for a motor power supply. It must be separate from the Arduino power supply.
But no matter, even if you wire everything correctly, you will have nothing but trouble. The motor you have chosen was not designed to work with the L298 motor driver and it won't. Instead, this low voltage, high current (3.4V DC, 1.7A) motor was designed to be used with an industrial chopper-type motor driver. Find another stepper motor that is intended for 12V operation or higher, at less than 1 ampere per winding and with a 12V, 2 ampere power supply you should be fine.
This forum is full of posts by people who made the same mistake, so don't feel badly!
You can find appropriate bipolar (4 wire) steppers in many, many surplus outlets, ebay, junked printers, etc. The motors linked below are just examples. The voltage rating is the highest steady-state voltage that the motor can tolerate without overheating, the same consideration holds for the current rating, for both windings at the same time. You can always add a 5-10 ohm, 10 watt resistor in series with a motor winding to reduce the voltage (and torque).
