Can you post whatever you have done sofar ?
We are here to help you when you have problems with your work.
We suggest that one starts simple to help build yor skills.
I would offer that an UNO and the RTC that you have picked ios a good place to start.
A relay will vbe useful with the bell part.
lots of code on how to get them to work .
give it a try and let us know you progress.
I have thought about this and would like to have it read from a USB stick so that it does not ring on holidays and weekends.
need to change dates yearly.
The TimeAlarms library might help.
