How to create TM1637 Digital Clock with setup Time and setup Alarm functionality

This is a prototype of the time and alarm setup mechanism which I am planning to use in my next digital clock projects.
I hope you find it useful.
If you think of any improvements please let me know. I would be more then glad to look into them and potentially incorporate in my code.

Here is the link to the project details including the code:
