I need a some help trying to get a motor working by switching it on through a more powerful battery. I havent actually done any electronics in a good 3 years and I wasn't very good at the higher power stuff anyway!
Basically I have a circuit that looks something like the one attached and I have a couple of MOSFETS and various high power transistors lying around, can some one help me with the calculations required for R1 and R2 and what sort of parameters would be good for the MOSFET/transistor?
I know the motor usually runs on 8.7v and draws around 2amps. If possible i would also like to reduce the draw of the motor and reduce its RPM, can that be done?
