That is my code and it keeps saying that it has an error compiling for board Arduino/Genuino Uno, and I have tried many things to solve this problem yet I cant seem to find a solution

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

And that is my error message

When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).

When your code requires a library that's not included with the Arduino IDE please always post a link (using the chain link icon on the toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger(Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

(  pinMode.INT_PIN INPUT_PULLUP);

INT_PIN has no value, pinMode needs a (, and you need.one of these ','.

If in doubt, refer to the examples.

4 
attachInterrupt(digitalPinToInterrupt( ), lightInt, FALLING);
}

Which pin do you want for the interrupt?

5

Well, be sure to pick just one.

Edit: someone just removed a post before this reply. Please don't do that again.

Try:

#define INT_PIN 2 // INT0

outsider:
Try:

#define INT_PIN 2 // INT0

Thank you so much, that helped my teams code and we were finally able to verify it an upload it without any problems. :slight_smile:
