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!
Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the internet. There are certainly a lot of great services out there for datalogging, or communicating with your microcontroller over the web, but these services are either too complicated to get started, or they aren’t particularly fun to use. So, we decided to experiment with our own system, and that is how Adafruit IO got started.
To make it easy for people to get started using Arduino or ESP8266 we have starter packs with just about everything you may want to connect to the internet, with known-working WiFi modules! ESP8266 Huzzah Kit CC3000 Huzzah Kit
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
