I am trying to figure out how to replace a potetiometer with an "-" and "+" button.
The circuit is for a variable power supply. I would like to take a 24v 1A constant power supply and use the arduino uno to control a lm317 circuit with a digital pot. OR modifying an existing variable power supply. Problem is that out of all ive read it looks like I cant use the shields and break out boards that I can find on the web because they can only handle a current of 5v and under.
I am nowhere near proficient in electronics and this is my fist venture with the arduino. So I might just be missing some info, but I've noticed how capable the arduino is and know its possible.
