/*
  Security System using Arduino Bluetooth Camera Project

  This project shows an application on 1Sheeld's camera shield.

  By using this project, you can track whether anything stranger
  has entered your house and capture his photo  by using camera
  shield from 1Sheeld.
  
  OPTIONAL:
  To reduce the library compiled size and limit its memory usage, you
  can specify which shields you want to include in your sketch by
  defining CUSTOM_SETTINGS and the shields respective INCLUDE_ define.
