Controlling a 28BYH-48 stepper motor using ULN2003 stepper motor driver, arduino and potentiometer
Very new to this field of study and fun.  The code for the tutorial "Control a Stepper motor using an Arduino and a Potentiometer" is pretty much just what I am looking for except it uses an Easy driver to control a NEMA 17 stepper motor. 

My setup uses a 28BYH-48 stepper motor plugged in to a ULN2003 stepper motor driver board and Arduino Uno.  Could someone please show me how this code would look without this type motor and driver?  I don't have a DIR pin or a STEP pin and I also have 5 wires.  All I'm looking to do is ultimately set a Max and Minimum position across the potentiometer range.  I plan on hooking the stepper up to a mechanical variable capacitor which is the volume control for a Hammond organ (aka. Expression Pedal).

Thanks in advance...
