Hello everyone, new to the forums.
Need some help with a potentiometer.
Im trying to make a manual fan speed controller for my computer. I bought a potentiometer from Radio shack and wired it in (#1pin input, #2pin output,#3pin ground). But it doesnt change the fans speed at all. All it did was lower the fan speed by about 300 rpms. Where did I go wrong?
Heres teh specs of the fan I am trying to control 12v,0.76A,9.1w.
The potentiometer I bought - 50k-Ω linear taper potentiometer, 500vdc-0.5w.
Is it wired incorrectly? Im kind of new to electronics and teh specifics of them so be gentle![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
