Thanks Malc, Simon,
I now have an Arduino Uno board, and the software is installed and working.
I've done a small amount of programming over the years, visual basic most recently or should I say VBA in association with Microsoft Excel.
I thought that learning how stepper motors work, and maybe getting my small home made equatorial fork to be driven in RA by a stepper motor would be a good first project, for visual observing, not imaging.
Something else to play with on cloudy nights!
Thanks for the links etc.
Cheers
Chris
