-After overcoming the problems associated with this project and a lot of software debugging was performed we were able to successfully complete this project. Through out this project we learn about how to implement bluetooth communication between two microcontrollers from the hardware and software side. Understanding data sheets for the devices and obtaining the information needed to implemented the desire functionality from the bluetooth module, SJ one board, Arduino board, and cellular shield was crucial in order to obtain a successful outcome and create a fully functional text message security system.

Through out this project we learn how to implement bluetooth communication between two microcontrollers and being able to send and receive data successfully. From the hardware to software design and implementation, we learned the basics functionality for a security system. Due to time constraints, we were not able to incorporated an alarm sound. Understanding data sheets for the devices and obtaining the information needed to implemented the desire functionality from the bluetooth module, SJ one board, Arduino board, and cellular shield was crucial in order to obtain a successful outcome and create a fully functional text message security system.

-To sync our the devices and connect them via bluetooth we used an app called "AT command" from the Android app store which can be downloaded for free. First we make sure our circuits are powered on. Then we open the App and scan for nearby bluetooth devices using an AT command. once we see the desired device name/serial number, we store the serial number on the master bluetooth module. We then send another AT command connect to the master SJ board to the slave SJ board so that they can communication thru bluetooth. Note that one bluetooth module must be set to master, since the module default state is slave.

-This security system will be using GPIO pins on the SJ One Board to detect if the laser has been trip. It will use TX and RX lines to connect to the RN42-XV Bluetooth Module using serial communication (UART). There two Bluetooth modules, each one is connected to a SJ One Board and will communicate with each other, in order to specify when we should send a text message. The Arduino module will provide power to the cellular shield and retrieve the information from the slave micro controller to send the according commands to the cellular shield.
