Hi all, I'm stuck in a bit of a predicament.
I have a project that needs to be done by the 26/05/2017... Just 5 days away from the date writing this so fast replies would be much appreciated.
I am trying to run a 4-pin 12V PC Fan using an Arduino Nano, a Fairchild FQP30N06 N-channel MOSFET and a 10k OHM potentiometer; I'm using a 12V battery to power the fan.
However, I am very very new to this; I have no understanding of C and I have no idea about electronics; I'm a complete beginner. I have looked all over youtube and the internet but all guides for this seem to be non-noob friendly.
Would anybody be able to show me a noob friendly link or would anybody be able to give me a digram on how to wire it properly and how to program it? I want the potentiometer to change the speed of the fan as it is twisted.
I copied a simple circuit which was designed for a 2 pin DC-Motor but only the last couple of mm's of the twist would move the fan and it would move at a very slow speed; that was using the TACH pin on the fan as it would not work with the PWM pin.
Could anybody please teach me what I need to do?
Thank you all.
