The Adafruit FONA 808 is an amazing little breakout board that integrates not only a GSM/GPRS chip, but also a GPS on the same board.

In this project, we are going to use the FONA 808 breakout board along with Arduino to make a cool geofencing project. This project can for example be used on objects that you don't want to go after a given distance. For example, you could place this project in a bag, and immediately know if it has been stolen.

Basically, we'll be able to tell where the project is, and calculate the distance between it's current & initial positions. We are actually going to build two variations of the project.

First, we will use a simple on-board alarm system, composed of a LED and a Piezo buzzer, to tell when the fence has been breached. Then, we will use Adafruit IO to track the location of the project in real-time, and immediately know if the fence has been breached from the Adafruit IO dashboard. Let's start!
