Hey
Can someone with electrical talents help me out?
I'm putting together a stir plate.
I have a 9VDC power supply and a 12VDC .21Amp fan.
In between I have a toggle on/off switch and either 1 or 2 25ohm potentiometers.
No matter how I configure it I can't get the potentiometers to vary the fan speed.
Any suggestions?
Thanks.
