Could you use relays to control your driver micro stepping with the Arduino?
Thanks for the comments!
You could probably use relays, but they would have to operate really fast and operate a lot. I would suspect they would fail after a while. There's also the potential problem of contact bounce.
The EasyDriver looks like a great?one for? a loop tuner. I wish the one I'm using had the ability to program the step size on the fly. That would make it possible to do large moves of the capacitor?faster, then one could reduce the step size for fine tuning.
I'll be interested in hearing about your project.?Feel free to email at my callsign at?ARRL.org.
