Hay ya all.
Im playing around with a display for the front of my PC, i've made an adjustable 3-12vdc circuit to control the speed of my fan on a server.
but i wanted to be able to see the output voltage on a led display type. so i looked around got some bits got 25% of the was through building it and stopped dead in my tracks.
now, if im reading the simple circuit (link to follow) right, the adjusted voltage Vin is Neg.
the voltage circuit adjusts + not -
is there anyway to alter this circuit (link to follow) to monitor the Pos instead?
