Has anyone used a serially controlled potentiometer that has a max value of 10KOhms and can handle 10VDC? I would prefer recommendations for a potentiometer...

I have been down this road, there is a 5.5V limit on all pins. I discovered this after I installed a board that uses one and it doesn't like 10V at all. I am...
... Well, you *could* use an RC servo, a bit of coathanger, and a linear 10K pot. Alternately the PIC/digital pot and some resistors and a transistor would ...
... The output of the transconductance opamp type 3080 is very much like a pure resistor and goes from rail to rail almost - a very nice design item. You can ...

Take half the voltage of the 10V supply as your reference. Then multiply the potentiometer output voltage by 2 working off the low side of the potentiometer as...
A lot depends on what you really need which isn't clear to me - but it doesn't sound as though you need a potentiometer at all. Is it: A. A digitally...

Many shocks on cars have this type of fluid in them now. The car's computer can adjust the ride of the vehicle by increasing or decreasing the magnetic field...
You can use a 'dimmable' ballast that has additional connections for a dimmer pot to attach (if they still make this type of ballast). Connect a solid state...
