controlling a manual turn pot with arduino - greater then 5v - for CC CV

controlling a manual turn pot with arduino - greater then 5v - for CC CV

i would like to control items that have a POT on them with arduino

like a buck or boost converter . or some other device.

most of the time the voltages on the pot are over 5v

any idea? thanks

You need to be more clear.

Do you want to mechanically turn a pot?
Do you want to output a control voltage?
Do you want to replace a mechanical pot with a digital one?

Often power supplies have control inputs to bypass any front panel controls.

replace a mechanical pot with a digital one, with a ranger over 5v.
to control a boost buck converter or similar which will range with the output

Then you need to research digital pots - but be careful, sometimes the voltage range is very limited, so if your pot has a lot of voltage across it, you may be out of luck.

PLEASE stop making new threads all the time - stay in the threads you already made!

Hi,

What then is the preferred thread to reply to?

Quick reply:
It would be interesting to make an actual analog pot control mechanism too. This would mean controlling just about any power supply, albeit a little more slowly than we would like to, but if it is just for setting the voltage one time (other feedback for the actual regulation) then it could be useful. The pot would get worn out if operated too many times of course, but probably no more than if we set it manually.
I guess some sort of geared motor drive or stepper might do it, with basic feedback to determine when the right voltage had been set, then leave it as is until the user decides to change the voltage again.
