HELP PLEASE! DS3231 RTC clock won´t work (and I need it to work asap for a college project)

OH! I noticed it was different so I changed that but still it wouldn´t work, but since Koepel recommended to change the library to a better one I´m not worrying about that one. And how can I use code tags here? (there´s a little icon like this: </> that´s what I used to paste the code before but it doesnt look quite like the other codes on here, let me know how to properly post code please :hugs: :grin: )
