Hello,
Newbie here.
I currently have a LED driver with a dimming function that is controlled via a variable resistor and connected via low and wiper on the variable resistor.
I would very much like to replace this with a digitally controlled equivalent. I am looking at something like the AD5220. But I am unsure how to wire the pins.
I know:
- and + for power to AD5220
A and wiper for output to LED driver
But how to move wiper?
I want to control this so that the wiper can be moved "up or down" in either direction via a signal pulse, which is the bit I am struggling with.
Any help much appreciated.
Cheers,
