Control of a stepper motor

[Marauder_Pilot]

Hey, for my current project, I need to control a stepper motor. However, I have no idea how to do this. Can anybody point me towards some resources for controlling one?

use a stepper motor controller?  There are many of them out there... what are the motor specs?  If it is small enough, you can drive it direclty with a microcontroller (as in http://www.picaxeforum.co.uk/showthread.php?t=7827).  For most steppers, you will need a Stepper Motor Controller... TLA has been making the "Little Step-U" for quite a while... http://www.tla.co.nz/lit_step.html

If you never work with Stepper Motor, then it wil be better not to go with Microcontroller first. You should learn the control sequences and should learn the basic stuff to control a Stepper Motor. You can read my post about Stepper Motor Demo at http://www.societyofrobots.com/robotforum/index.php?topic=5055.0. It contains all information you need and covered with useful Photos and Video.
