In tutorials I've read regarding linking an Arduino to an LCD display, it seems a potentiometer (dimming module) is already used for that. I dim COB LEDs with a potentiometer, and I was wondering if it were possible to connect the potentiometer (which dims my LED fixture) to an Arduino, then display the dimming value in 0-100% format on an LCD display.
This would be of great help to me for my COB LED projects. I have no problem investing the time into learning this, if its possible of-course. I played around with Java a bit years back so I have a moderate understanding of programming syntax.
What voltage / current goes through your potentiometer?
There are tons of on line tutorials (eg first hit in google) to display the value of a pot on a LCD. The one thing to be careful about is to ensure you don’t grill your arduino by sending 110V or 220V (or 12V / 24V) into its analog pins.

The fixture I'd like to implement this to would be 18 COBs with variable forward voltage, so a range of 50.5fV-51fV per COB @ 1.4 amperage max. I say 1.4 because that's what the driver is rated at, but I'd never push the COBs that hard so more like 1.0a max.
