Everything You Need to Build the Project from Scratch

PLEASE READ THIS DOCUMENT IN THE ORDER IT IS PRESENTED

Hardware Requirements

Arduino Microcontroller Board
Nano version recommended due to its weight and size
Raspberry Pi Model B or B+
4GB (or more) SD Card
Bluetooth HC-05 Model
Bluetooth Dongle
Solder Station
One 70X50 Perfboard
A breadboard would suffice, but I wouldn't recommend it
Some single-row Female Pin Headers
One [1 - 10] KΩ Resistor
Stranded Wire Cable
A jumper wire kit if you're planning on setting the circuit up on a breadboard.

Optional Hardware Requirements

WiFi USB Adapter for the Raspberry Pi

Building the Signal Sender Device

The circuitry of the signal sender device is fairly simple. Following is all the connections you need to make between the Arduino board, HC-05 Bluetooth chip, and the Sonic Alarm system. The hardest part is perhaps figuring out where the VCC and GND wires in the sonic alarm system device are.

NOTE 1: You may want to disconnect the buzzer from the alarm system.

NOTE 2: You can build as many of this device as you want. The server capable of detecting and connecting to them all.

NOTE: The pins on the HC-05 module have been reordered to make the circuit diagram for clarity.

If the circuit diagram is blurry on your screen, clicking on the diagram will load the image with its original dimensions.

Configuring the Signal Sender Device (The Arduino Board)

Now that you have soldered all the components of the signal sender device together, it's time to give the device a brain to process the signals. By processing signals, we are referring to the process of recieving input from the alarm system device and sending it over to the server (which we are yet to configure) via bluetooth.

In order to burn the brain onto the Arduino board, you need to have the Arduino IDE installed on your computer. If you already have the IDE installed on your computer, you may simply skip this step. If you would like to do this step on a Linux machine, simply type sudo apt-get install -y arduino to install the IDE on your computer. If you are, howerver, doing this step on Windows or Mac OSX, then you need to visit the official Arduino download page to obtain the proper software and a through installation tutorial.
Fire up and Ardunio IDE software and click on Tools, hover over the Board submenu with the mouse, and select the Arduino Nano w/ ATmega328 option.
Click File, Open, and use the browser frame to navigate to Signal Sender -- a subdirectory located under the main project directory. In this subdirectory you will find a file named Triggerer.ino. Click it, and then click Open. This will load the content (source code) of Triggerer.ino into the IDE.
To upload the source code onto the Arduino board, click on the icon (the button with the arrow pointing to the right). To make sure you are clicking the right button, hovering over the button with the mouse will print the word Upload right next to the icon itself. This process takes somewhere between 10 and 30 seconds.

NOTE: The IDE prints out Done Uploading. when the upload process is complete.

Configuring the Pi

The process of configuring the Pi includes: Downloading and installing a Linux system on the Pi. Hooking up the Pi to a stable WiFi router (either via an ethernet cable or using a USB adapter). Cloning the seQre repository from GitHub. Localizing the Pi

Setting Up the SD Card The process of setting up the SD card includes: Downloading a Raspberry Pi-compatible Operating System. Burning the Operating System to the SD card.

The official Raspberry Pi download page contains a variety of Raspberry Pi-compatible operating systems you can download and use. I do, however, recommend using RASPBIAN, since it comes with most of the utilities you need to run this project.

To download the RASPBIAN OS on Linux or Mac OSX, type the following:

        cd ~
        wget --content-disposition http://downloads.raspberrypi.org/raspbian_latest

On Windows, simply click here and allow your browser to download the 20##-##-wheezy-raspbian.zip file.

If your Pi is connected to the network via a WiFi USB Adapter, you may want to set it up to connect to your router automatically at boot-up. Here's how you do that:

If you don't have git already installed on your Pi (which you should already have built into the recommended Linux system), install it with:
```
sudo apt-get install -y git
```

The last step in this process is localizing the Pi. By localizing we refer to giving the Pi a local http address, so you don't have to worry about figuring out its IP address and/or memorizing it. Here's how that's done:

Install avahi by typing the following command

        sudo apt-get install -y avahi-daemon

To specify a local address, type the following commands

        cd ~
        touch hostname
        echo "seQre" > hostname
        sudo mv hostname /etc/

The system now needs a restart to pick up the new new local address. Restart the Pi using

        sudo reboot
