hi all,

I need help with putting together a simple fan control electronic module with the use of a potentiometer. I put together a simple connection on a 9V battery but it kept burning my potentiometer.

OK, I know nuts about all these, so need help here. If you can layout to me an easy circuit diagram, the components (resistor, capacitor with specs), type of potentiometer, etc, I will go buy it from SLT.

I googled some sites, but I understood nothing out of it…

*** Oh btw, this is not for PC fans etc. Its nothing to do with PC, computer cooler stuffs. Im just doing this for some other applications, non computer related.

Thanks.
