This script creates an access control system that only requires each user to have a basic cellphone that can make a call.

Here is what you will need

  1. Raspberry Pi
  2. Piface Digital Addon Board
  3. An electronic lock, wired up to the first relay on the Piface digital.
  4. A Twilio number
  5. Pord forwarding on your router
