I have parts from a very old dead floppy disk drive I took apart and one part is what I imagine is a little stepper motor that was used to run the R/W head in and out over the floppy. Now I'm wondering if I can make it do something with an arduino? It was from an old panasonic floppy and has a paper sticker on it that says 1406B1624 (but google never heard of that). It has 4 copper foil leads on a plastic strip attached to it. Any ideas what kind of stick to poke it with? :-).
If it has 4 wires my guess is it's a standard bipolar stepper motor. Use something like this to figure out the wire pairs:
Once you know that, you can use something one of these to connect it to an Arduino:
Good luck!
Thanks for the links! Don't know if I'll ever try to do anything with it, but it is nice to have the pointers. (Of course one of the likely reasons the floppy drive was dead is that the stepper motor was busted, so I'll have to take that into account if I start playing with it :-).
