I cannot seem to find any good or understanding Ardumoto tutorials online... for stepper motors.... however tons of people seem to be using them just fine without a hitch!!
I bought a Arduino Uno (SparkFun Kit) and also the Ardumoto, and a Motor (ROB-10846) all from SparkFun. well technically Creatron Inc, however they supply Spark Fun Kit. great kit you guys have!!! Went through all of them in about 4 hours and had a great experience and understood it all pretty well The kit was amazing, however now Im moving to bigger and better things.... Stepper Motors ( as this is what I really bought all this for) any good tutorials,examples would be great.... please help I understand the motor is BiPolar, and has 4 wires, A (Black,Green) and B (Red and Blue)on the board I have them wired like so B3= Blue B4=Red and A2=Black and A1 = Green my question is which port should each colour go in, on the Ardumoto, I know their is 4 ports, and 2 per side A/B but can they be in any order for each side??

Learning Examples | Foundations | Hacking | Links Examples > Stepper Library Stepper Motor Knob Stepper motors, due to their unique design, can be controlled to a high degree of accuracy without any feedback mechanisms.
The shaft of a stepper, mounted with a series of magnets, is controlled by a series of electromagnetic coils that are charged positively and negatively in a specific sequence, precisely moving it forward or backward in small "steps". There are two types of steppers, Unipolars and Bipolars, and it is very important to know which type you are working with. In this example, a potentiometer (or other sensor) on analog input 0 is used to control the movement of a stepper motor using the Arduino Stepper Library. The Arduino will connect to a U2004 Darlington Array if you're using a unipolar stepper or a SN754410NE H-Bridge if you have a bipolar motor.
For more information about the differences of the two types, please take a look at Tom Igoe's page on stepper motors. Circuits.

A stepper motor is a motor controlled by a series of electromagnetic coils.
The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate. This design allows for very precise control of the motor: by proper pulsing, it can be turned in very accurate steps of set degree increments (for example, two-degree increments, half-degree increments, etc.).
They are used in printers, disk drives, and other devices where precise positioning of the motor is necessary. There are two basic types of stepper motors, unipolar steppers and bipolar steppers. Unipolar Stepper Motors The unipolar stepper motor has five or six wires and four coils (actually two coils divided by center connections on each coil). Bipolar stepper motors The bipolar stepper motor usually has four wires coming out of it. Two-Wire Control BX-24 code: PicBasic Pro code:
