Hey all, I'm actually a bit new to potentiometers, but I have an LCD display that measures voltage coming soon, so I figured it's time to make a variable power supply. Thing is, I'm not sure how to find out what potentiometer I need. I need one that can bring 12 volts all the way down to 0 (well, 10 since thats all the display can handle). Anyways, what value/range (if that's right) potentiometer will I need. Also, what's an easy way to figure it out for future refference?
