Arduino GPS Tracking System

GPS Tracking System schematic

This was easily the most time I’ve spent producing an Arduino Tutorial. I’ve been sporadically walking around NYC with this Arduino GPS for weeks as I’ve tweaked the code and gotten it just right.

If it wasn’t obvious from the title, this tutorial will teach you how to use an arduino paired with a GPS Module and an SD Card Module to log your latitude and longitude over the course of a day. As a bonus, I’ll also show you how to easily overlay this data onto a map using services like Google Earth and Google Fusion Tables. I added a short “history lesson” to this episode to explain how Arduino GPS came to be; it’s the first time I’ve done that, so please let me know if you like the extra knowledge. Grab some popcorn and your Arduino, because this tutorial is pretty long – GPS is complicated! The schematics, programs, parts list, sample data, and important links are available for below.

I used the tinyGPS library to decode the NMEA GPS Data. Cooking-Hacks generously supplied both the GPS shield and SD Card shield that I used in this tutorial.
