This is my first post here so please tell me/forgive me if I screw something up.
I have been banging my head against a wall for hours trying to get my Mega to control a 4 wire PC fan via PWM.
I have installed every library I can find and tested ever block of code, but the best I can get the fan to do id drop to it's minimum speed. It won't adjust anywhere in between high and low.
I've tried multiple different fans and multiple different frequencies (some of the code I've found allows for easy adjustment) but nothing seems to work.
I'm a total newb with a knack for logic but a lack of brain power sufficient to really dive deep enough to understand what happening in the background in order to actually make this work.
If anyone can be of any assistance I sure would appreciate it.
