If you're anything like me, you probably look at all of these Arduino projects and think to yourself, "damn, I wish I could do something like that!" Here's the thing: You totally can, and this nifty Infrared Alarm project is the perfect starting point.
Using an Arduino microcontroller and passive infrared sensor, you can detect invisible infrared light. Why would you want to do that? You could use the device to scare off the neighborhood kids, zombies, or even the neighbor's cat that won't stop eating your vegetable garden.
The infrared sensor doesn't actually measure movement, but instead it measures the temperature differentials and determines when a new object is within the sensors range. The sensor then sends a signal to the Arduino microcontroller and then determines if it should sound the alarm.
The project is pretty simple, and uses a breadboard so there's very little soldering needed to put your new anti-zombie detection system together. The steps are available on the Makezine Weekend Projects website; the page has links to Radioshack's parts listings, which makes it really simple to gather the components necessary to build your device.
Stop with the excuses, and jump into the Arduino world headfirst. It's time you unleash your inner geekery.
