Hi guys, I'm trying to use the pwm signal from my arduino to control a motor with 12v, I'm following this diagram, with the exception I'm using an IRF540: [image] Is there anything wrong on the diagram above? The only way I was able to use the pwm signal was with this other diagram but this one do…

Can't figure out how to use pwm with an optocoupler and a MOSFET

How are resistors (R2 and R3 ) chosen for mosfets? How are they calculated?
