This project requires breadboard, Arduino, 5V General purpose USB charger, Laser chess game mirror, Laser, enclosed piezo element, Breadboard hookup wire kit and Laser mounting stand along with same basic tools like Third hand tool, Computer with Arduino IDE for programming etc.We do understand the urge of keeping our house, work, family safe from intrusions. This project by Ben miller, co-founder of Bluelock.com, guides us how to construct a laser tripwire that buzzes an alarm assoon as the laser is disturbed. This tutorial is based on photo resistor that senses the laser beam and usespiezo to play alarm from an Arduino without an amplifier
