I am wanting to design a project to control a stepper motor.

Do I need a motor shield to control a stepper motor or can this be done straight from the UNO

I am a complete newbie and just trying to identify the parts I need for purchase.

Thanks

try EasyDriver
seems a popular choice

what setppers are you using?
there are only 10 types of people
them that understands binary
and them that doesn't

If it's a really tiny stepper then yes.  :)  I doubt you'd be able to find that kind of motor though, so no, you are going to need something external to switch higher currents.

OK, so it seems I do need a shield. Thanks All

I have not yet identified a stepper to use but the one I have looked at (well the only stepper that Arduino supplier here in the UK seem to stock) is the http://www.sparkfun.com/products/9238


One question I did read about a while back on the main Arduino site but can not find it now is what happens if you have completed the project and want to use it out in the field, do I still need the Arduino UNO or can I (as I thought I had read) was replace the Arduino with a Mega Controller chip. Any pointers to tutorial about this would be great.

steppers (not setppers - sorry bout that)

you could also try zapp for steppers
they have quite a range, £10 for the NEMA-17

and ProtoPic for drivers
there are only 10 types of people
them that understands binary
and them that doesn't
