Start by posting your code

DS3231  rtc(SDA, SCL);

Does the constructor need the parameters ?
It seems not

See reply #1

I would start with a sketch that only works with the DS3231; remove the rest (use serial monitor) for debugging purposes.

Once you get that working, write test sketches for the other components.

Once you have figured everything out, combine.

By the way, when posting code on the forum, use code tags; please edit your reply and
Type
** **[code]** **
before your code
Type
** **[/code]** **
after your code
