Hello first post here, I'm looking for some help designing a basic circuit.
I have a few high speed 40 000rmp slot car racing motors I purchased for this project the voltage rating is 9-15V. I don't know what the amperage is but guess mA (can see the motor below if it helps)
http://www.mrrc.com/car-components/motors/motors/motor-s-can-speed40-mt-p540-40000upm/12v
What I want to do is use an optical slot switch so that when the slot is covered the motor accelerates as full speed in one direction and when the slot is uncovered I want it to reverse polarity and accelerate in the other direction but with adjustable speed (0 to full speed).
I have a basic understanding of physics, did some very basic electronics in high school but very rusty and need help.
I want the circuit to be simple,small and robust....any ideas?
