Right... that's the problem I was trying to point out with the method of As the battery wears out, or if you just want to use a different speed, the amount of time to do something will vary. A potentiometer used in this manner measures revolutions, not speed. The amount of revolutions to go a certain distance or make a certain turn will be the same at any speed, assuming that your wheels are not slipping on the driving surface. Does it make more sense now?

Yes, thanks
