Powering an Arduino Nano with a 12v Battery

tinman13kup:
The problem comes if you wish to power anything else off the 5V pin of the nano

This might be a stupid question but does this include connecting a potentiometer to 5V pin?

Or maybe better to ask, will this work without a buck converter or do I need one in order to power arduino with less volts?
