Hello Guys,

I am new to the forum and couldn’t find an appropriate answer for my question.
I’m a little stuck. What I would like to do is to control a DC-Motor. The thing is, that I would like to adjust a fixed speed via a potentiometer and just change the direction with a simple digital output (I am afraid I don’t have much more to spend).
What would be the easiest and cheapest way to achieve this?

Best Regards and Thank you for your help

Which DC motor you have in a possession? Or you are planning to buy one?
