Thanks in advance for any help offered.
So I have a 12v dc motor and connected power module. The speed of the motor is controlled by a 10k pot.
I want to remove the pot and have arduino control the speed instead. I know I can't connect the 12v directly to my Arduino and the signal will probably be analog in nature (simulating the turning of the pot).
I was thinking an optical-isolator. Buy everything I find wants to control a relay. I see talk of a triac. Would that work?
And what about the circuit itself? Or is there a shield out there I'm missing? I don't think a PWM solution would work in this situation, or would it?
Thanks again for any assistance given.
