Hey guys.
I am working on a solar electronics project just for education and fun really, and what I want to do is use a pot to control the speed of a small motor.
The solar cells turn the motor in direct sunlight but I need to regulate it and turn the speed up and down.
My solar cells are wired in parallel and putting out 5.5v and apparently they give 90ma each but I have only seen 130ma on a good day.
I see all these different resistance strengths for pots and I have looked today at it and I am still confused.
I take it I need a linear pot ? but what I am unsure of is the resistance of one given the above voltage and amp rating.
If anyone can help it would be much appreciated.
Many thanks
