Weekend Projects – PIR Sensor Arduino Alarm

Weekend Projects – PIR Sensor Arduino Alarm

This project is great for those beginning to build with Arduino, and requires no soldering. Using very few components, and some jumper wire, we’ll build a simple motion-sensing alarm. This project combines technologies we’ve used in previous Weekend Projects, including a PIR sensor and piezo buzzer. It’s great for practical jokes and doubles as an early warning system for the zombie invasion!

Jason Devine of Ireland wrote in with another project by his two sons, ages 11 and 9. Last time they built a clenching Lego hand. This time, Jason challenged his kids to make an iPad stand with as few bricks as possible. Check out the boys’ website for more projects.
