Stepper motor control

[Clive]

Hi newbie question I'm afraid, can anyone suggest please what I need from Hobby Components to drive their stepper motor and ULN2003 Board so I can push a button to drive the motor and stop via a micro switch and push a second button to reverse the operation and stop via another micro switch, also with variable slow speed control, would prefer to keep it simple if poss without using an Arduino or is that the way you have to go? thanks in advance, Clive.

Hi Clive,

Although you could certainly do it with one or more 555’s, shift registers, and some 74 series logic, I think the simplest solution is going to be an Arduino I’m afraid. An Uno would easily do it, or even just a Nano which is just a cut down Uno.

We do have an example sketch which you can find in the first post of this thread:

It basically rotates the motor forward and backwards one rotation and you can specify the speed. That would get you a lot of the way there.

Hi Andrew, that's great thankyou, Arduino here I come. Thanks for your reply.
