so whats the benefit of let's say controlling motor speed with just a potentiometer or a potentiometer hooked up to the gate pin of a MOSFET
I get it. With the PWM of the Arduino, I am giving the MOSFET only the power it needs, so it doesn't have to dissipate as much unwanted heat. Isn't there also actual code to where I could separately run the pot to the A0 of the Arduino. Then have the MOSFET hooked up to a digital PWM pin? else.Thanks!!
