Hello, I would like to ask what is a general approach to use an arduino (or any other microcontroller for that matter) to turn on and off a bunch of 12V fans? I am using 7 12V fans, and they draw around 1A of current when all of them are on. i have a 12V rail that i cen get the required current fro…

Turning on and off 12V fans using arduino

As i understand this mosfet would be fine: Lemona ?

Should i connect a small resistor to the gate?
And also should i add a pulldown resistor? What value?
