How to build a Raspberry Pi home dashboard

I decided to write the dashboard in Python 3 and use the flask framework because I wanted to build up my Python 3 skills. I also wanted to be able to play with NFC (Near Field Communication) tags and see what they could do.

The concept behind the use of NFC tags is that it allows you to place tags in various locations, touch your phone on them, and use the NFC reader app update my dashboard at home.
