I want to control the stepper motor from a laptop but haven’t seen anything here that shows how to interface the controller to the computer. Can someone explain what hardware and software I need?

I think the easiest way for you to do it is by using the original [[USB Bit Whacker](http://www.sparkfun.com/commerce/product_info.php?products_id=762) or [[Arduino](http://www.sparkfun.com/commerce/product_info.php?products_id=666), [[EasyDriver v3 Stepper Motor Driver](http://www.sparkfun.com/commerce/product_info.php?products_id=8368) and a simple motor like [[this one](http://www.sparkfun.com/commerce/product_info.php?products_id=8420)…

Using the Arduino may be easier for your projects due the amount of tutorials currently floating around the internet…

If you decide to use the Arduino, on [[Brian Schmalz’s site](http://www.schmalzhaus.com/) (creator of the EasyDriver series), their is a [[link](http://danthompsonsblog.blogspot.com/2008/09/easydriver-v31-tutorial.html) for a project that is exactly what you need…

BTW, i think this should have been posted in the projects part of the Forum…]([Dan Thompson: EasyDriver v3.1 Tutorial](http://danthompsonsblog.blogspot.com/2008/09/easydriver-v31-tutorial.html))]([http://www.schmalzhaus.com/](http://www.schmalzhaus.com/))]([Stepper Motor - ROB-08420 - SparkFun Electronics](http://www.sparkfun.com/commerce/product_info.php?products_id=8420))]([EasyDriver v3 Stepper Motor Driver - ROB-08368 - SparkFun Electronics](http://www.sparkfun.com/commerce/product_info.php?products_id=8368))]([http://www.sparkfun.com/commerce/product\_info.php?products\_id=666](http://www.sparkfun.com/commerce/product_info.php?products_id=666))]([USB Bit Whacker - 18F2553 Development Board - DEV-00762 - SparkFun Electronics](http://www.sparkfun.com/commerce/product_info.php?products_id=762))

Thanks for the reply. It’s still not clear how I can interact with the controller using C#. Is there a compiled dll that can be called?

Does each command have to be sent to the microcontroller (either Arduino or the USB Bit Whacker) or can the stepper motor controller be interacted with directly?
