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!
