Hello, I have a problem because I do not know how to start code from menu on 16x2 display.
So I have 4 buttons to navigate the menu and change the values in the menu. I want lcd to go out when buttons are not used. It looks like this: nothing is pressed, at pin 1 is LOW status and lcd is off when I press any button pin 1 goes HIGH for 30 seconds unless I press a button again then the timer will reset and it will measure from the beginning as time passes pin 1 is LOW. Can anyone give me some sketch of such a program for lcd blanking?
No, but you can write it and post it here for help. Using code tags please. The LCD library that you are using should have some basic examples that you can start from.
