I am trying to control a 12V DC fan with PWM using an IRFZ44N MOSFET. However somehow the fan is not turning on and off when the gate is pulled to either 0V or 5V (on the power supply). And it is definitively not working using the PWM pins on the Arduino Uno. Next to that a 2/6/12V battery charger is used to power the fan. It is rated at 600mA, while the fan is only 300mA.
The question is: what is broken in my circuit? Maybe the power supply can't handle the PWM action, or my MOSFET broke (I might have over-voltaged it on accident)?
I connected it exactly as in this video.
Thanks for your time in advance! Bas
