This project demonstrates how to add extra security to a bag. The project could be adapted to any bag. I chose a bag that holds one of my precious possessions, my laptop computer. To prevent any unauthorized persons from getting their hands on my laptop, the project implements a hidden security panel disguised as a normal zipper. Unless the bag is deactivated, it will sound an alarm to notify that someone is poking around my stuff.
This project introduces you to analog sensors and continues with more advanced sound generating with the Arduino. The project also introduces new commands in the Arduino programming language, as well as how to work with serial communication for sending data back to your computer.
