Hey guys! Im doing a project in school where im using a menu on an LCD display and four buttons to navigate. The microcontroler im using is Arduino. I got the program for the LCD from http://www.coagula.org/content/pages/tutorial-manage-menu-and-lcd-display-arduino, and it is working perfectly! But i want to combine it with a photoresistor, so when i press a button and the value is to high, the screen will say "Make the room darker" or something like that. And if the value is low enough it will proceede to submenus.
