This project is about developing a multi functional NFC enabled doorlock for the exterior entrance to the new SENSORICA lab space.
The proof of concept will provide access using NFC while controling an LED strip to inform of system state (access granted, access refused, programming mode, etc..). A motion sensor will provide some interactivity and a wireless remote will also grant access to the lab space from within and notify the lab responsible that there is someone at the door.  


The first prototype is built using materials at the lab and NeoPixel strip donated by the KING:

* Arduino UNO R3
* Original door striker which takes 12-16V AC
* MFRC-522 reader/writer 
* 5V relay breakout board
* 12V AC wall wart transformer
* NeoPixel LED strip (108 LDED's)

Installation:
