With the prospect of getting a car close on the horizon, the idea of tracking where I go in case my car gets lost or stolen seamed quite cool. TVTS is Arduino based tracking system, using the Maplin GRSM shield and Maplin GPS shield. Only one problem; you can use the “TinyGPS” library to talk to the GPS shield but there is no library for controlling the GRSM shield, so I made one!
This project uses the GRSM shield to receive SMS messages and then reply with the devices current location and speed. I later added a function to send the devices location over encrypted UDP to a collection server.
