Mosfets have a different pinout generally speaking than normal transistors, the Gate pin is on the left in that picture, Drain is the in the middle, and Source is on the right.
Roughly translated: Left pin goes to the Arduino, middle to the fan black wire, and right to GND.
Despite the datasheet
That may fix it right there, if not try adding a brief kickstart to the code, set it to 255 briefly and then down to whatever speed you're after.
I changed the wiring....but same result.
2 reasons why I don't think a kickstart will work....firstly, it doesn't help if I spin it a bit with my fingers. Secondly, when it goes down from full speed to medium speed, it stops and you can hear the funny vibrating sound.
I might just ask the tutor on Monday, it's not due until the 10th.
Thanks a lot for your help so far!
