seems a popular choice
OK, so it seems I do need a shield. Thanks All
what setppers are you using?
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.
