Arduino House Lock.

This app sends commands to an internet connected Arduino with Wifi Shield to open or close a door.

Authentication is currently done through the Single Sign On System of The University of Texas at El Paso.

Photographs

Interface

Navigate to / to access the user list /doors to access connected door lists.

Instructions

1. When deploying this app, sign in with your UTEP Miners account.
2. Login to the production console by doing rails c production.
3. Give your user admin rights User.first.admin = true
4. Now you can modify access rights to the door.

Arduino Code

Switch to branch arduino-code to see the Arduino sketch that is uploaded, change the values of your SSID to use.

Logic

The app uses a status page located at /doors/{door_id}/status. Then a WifiClient on the Arduino connects to a Wi-Fi Network, navigates to the page and does a GET request. The results are then parsed and the tag <status></status> is searched for. A boolean value is given to state the current status of the lock.

The WifiClient on the Arduino repeats the GET request every given interval.

To Do

• Make system accessible without a miners account, another type of authentication, social media accounts?
