Door control system

Overview

Runs on Flowers, and code is on Github.

Access list is currently a text file, copied via a script from Babbage or Flowers. The text file just consists of card ID and name. To add a card:

babbage:~$ cd /usr/local/share/Doorbot
babbage:/usr/local/bin/Doorbot$ sudo git pull
babbage:/usr/local/bin/Doorbot$ sudo addid.sh

And then touch the card to the reader next to the Makerbot. Alternatively, connect to Flowers:

flowers@flowers:~$ sudo screen -dr doorbot

And ^A ^D to disconnect

The door opener connects to robonaut on Babbage to announce whenever the door is opened, and also flashes the lights on using Lighted, also on Babbage.

Override

ssh flowers@flowers
sudo doorbot/openDoor.py

The password is hackspace. If the arduino has somehow changed port, you might need to edit that in openDoor.py

Please use this with caution. Once unlocked, the door must be physically opened and closed again to relock.

If you unlock the door remotely, use the webcam to check someone has entered the space.
