Overview

This is a NFC-enabled smart lock designed to replace a standard deadbolt assembly.

The team of two will design and assemble an electronic, Arduino-powered drop-in deadbolt assembly that can be unlocked with registered NFC-enabled devices such as the Apple Watch, newer iPhones, or most Android phones. The lock will be powered by a Particle Photon chip running on an Arduino Uno board; the Photon will be web-enabled and NFC-enabled, allowing it to check NFC credentials and be operated remotely from a web app or mobile app.

A detailed user story indicating the flow of events that allow the lock to function:

  • John Doe registers a particular NFC-enabled device on the web app
  • John approaches the door with the phone, and the phone recognizes the NFC signal coming from the Photon
  • The phone sends an encrypted HTTPS web request to the Photon's webhook API along with its unique credentials (UID or Serial No.)
  • The Photon accepts the request, checks the data against its list of registered devices, and decides whether or not to open the deadbolt
  • If the credentials are approved, the Photon will apply an electronic signal to the deadbolt servo, opening the door
