I have built this as part of a robot car project, However this set up works better as a stand-alone fan, than it does to drive a small wheeled vehicle forward. So sharing anyway.

Given the problems, give me a Chemistry set any day.

I have built a basic potentiometer controlled motor, this works quite well, just a little sensitve. But should be fine for what I need this for.

I want to build something for the science kit to make it easier to stir liquids. I have found a project for a DC motor controlled by a potentiometer. that also uses an Arduino microcontroller. This should be easy enough to build and attach a stirrer to. This can be soldered up, battery attached, power switch may also be needed.

Should then be easier to stir liquids for science experiments.
