We can use GPS in our phones to track them if they’re ever lost or stolen, why not do the same with your car? You could go out and buy LoJack or OnStar, but this DIY solution uses an Arduino Uno, a GPS module, and a GSM shield to send you text messages and updates as the car is on the move.
Instructables user Javis Vineer Gonsalves loves his car, and wanted a way to tell authorities exactly where it was if it was stolen or somehow got away from him, so he put this system together. All told, it’s not terribly difficult to do, especially if you have a little experience with electronics projects, and when it’s all finished you’ll have a low-cost GPS tracking system that doesn’t require a pricey subscription to a third-party tracking or security service. It also has the benefit of being able to show you where you parked, if you ever forget, without having to set up an app or install anything special.
