im trying to figure out the easiest way to make a menu on a 16*2 lcd using a potentiometer to scroll and a button to select. a library would help even more. i have seen lcd menus that use buttons to scroll, but not a potentiometer.
Yeah and with good reason. Try an optical encoder... looks and feels like a pot but it's output is a pair of pulses... not necessary to convert the analog voltage to a digital value and then use that value to select a menu item from a variable "Constant" the pot in place of a switch... That's one of the main reasons why you see either switches or rotary encoders.
