Functions? Creating a Radio Hub

Projects Programming

Ok the way I understand it is under my screen 2 if statement I should have a variable that tells me that screen 2 is displaying.

So

  if (customKey == '*' ) {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("The Coop Door Is");
    ScreenTwo=HIGH;
  }
}

Then have an other if statement

  if (ScreenTwo == HIGH){
     CoopDoor();
     delay(1000);
}

I think I used the delay correctly here. I want to check the CoopDoor function every second and display that change.
