Hi guys,
I'm building a stir plate and having an issue where the potentiometer doesn't slow down the speed. Its either on at full-speed or nothing at all. I'm not much of an electronic guru so I'll try and explain in details as much as I can.
80mm Pc Computer
100oHm Potentionmeter (Linear)
12V DC Power Adapter
Rocker Switch
Ground Wire -> Black Wire on Fan
Power->Rocker In, then Rocker Out->Middle Post on Pot
#1(0r #3, I've tried both post on Pot)-> power (red) on Fan
Any idea what's going on? This doesn't work too good because it goes from 0-100 and instantly throws the stir bar. There's an image attached if that helps.
Thanks for any advice!!
