I've been looking for a solid way to regulate voltage for large motors (i.e. 12v 3 amp) using Arduino. I've used PWM with transistors and mosfets, but I've noticed that as you lower voltage, you're also lowering current, and with motors, that's overall torque. Also, PWM can get pretty loud at differ…

Yeah, I'm just trying to avoid dropping $40 on a high amp motor driver.
