DIY Burglar Alarm Sends You A Text Message Whenever It Detects Motion

If you want to keep an eye on your home — whether you’re worried about burglars or just worried about the dog getting into places it shouldn’t — this super simple DIY alarm will send you an SMS message whenever it detects motion.

We’ve shown you how to create a web streaming, motion-detecting surveillance system using webcams before, but if that’s going a bit too all-out for you, this project is super simple, even if you aren’t that experienced with electronics. In fact, it’s a great way to get started with the Arduino platform. All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below.
