It's not in code tags. Edit your post to put the code between code tags. ('code' in square brackets ending with /code in square brackets) Do it automatically with the less, slash, greater icon and paste your code in between.

Hello
during my morning coffee I have tried to unterstand the functionality of your sketch, due to I´m completely derailed. :slight_smile:
You are using a function libary. Do you know how the members of this libary will act?
And is there any need to use the function libary?

4 
lcd.print(“Please Wait”);
delay(6000);

What is supposed to happen while the user waits six seconds? Certainly nothing in the processor.

5

What is connected to A0 and why do you expect it to read specific values?
