There are other things you need to do to get the RTC ready to be used. That snippet is useless.
Well after going over my code, apparently now everything works fine and it saves the hour, I got another question tho.
I'm trying to work with a bluetooth module, HC-05 to receive data from an app I made, and compare it with the hour from the RTC. what do I need to do so I can make the arduino receive data from the bluetooth?
