Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

By using open-source Arduino tools, security researchers are exposing security gaps in door-lock systems used by millions of hotels.

He’s using an Arduino Uno and an Ethernet breakout board to hook it up to the network. This allows him to send text messages to himself when the alarm system is armed, disarmed, or triggered.

Many people would be tempted to write a really simple script that would just open the door and connect without any real thought about security. After all, this is a one-off obscure garage door opener.
