I don't know much about stepper motors. The following site has a couple of circuits to drive them.

I have used some of his other circuits with great success. I am sure he could answer some of your questions.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I have saved many stepping motors and keep wondering what is the simplest and cheapest way to utilize these motors. I know you have to have some electronics to make them work. Can anyone steer me in the right direction to get started. Recently there was a topic on gearing a turntable and a stepping motor was utilized but not mention of electronics involved.
Any help will be appreciated.
