Using Fan with PWM built in....
#1
I just realised the fan I have reclaimed from an old PC has 4 wires and 1 of those is PWM, so no need for a MOSFET as it is already onboard.
Looks like I just have to connect 12v and then connect Arduino PWM output to blue wire and connect -ve's together
Thoughts?
