Build a Basic Infrared Motion Alarm with Weekend Projects


Are zombies trying to steal your yo-yo? Or do you want to booby trap the neighbor kid with a motion-sensing alarm? The PIR Sensor Arduino Alarm is great for both! Combining technologies we’ve used in previous Weekend Projects, this build is entirely solderless. It uses very few components, so it’s a great project for makers looking to get started with Arduino, or who want a quick lesson in digital I/O. The software program is provided, and many of you may already have these components laying around, but never thought to combine them together into an alarm.

If you build this project into an enclosure box of your own design, or come up with a clever use of spooking your friends with the alarm, be sure to send us an email with some actions shots or video, and a story about your build!
