[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. Th… ...

Sometimes security doesn’t need to be overly complex to be effective. Instructables user [1234itouch] recently built a simple laser tripwire alarm that can be mounted virtually anywhere, comp… ...

That’s when I saw several instructables (Laser Tripwire Alarm, Arduino – Laser Tripwire Alarm System, and Super Easy Laser Tripwire, among others) using a laser tripwire.

The Arduino powered Laser trip wire system project is currently over on the Kickstarter crowd funding website looking to raise $3,000 pledges to make the jump from concept to production.

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

Foundries.io has revealed that its security technology provides capabilities making the Arduino Portenta X8 the industry’s first system-on-module (SoM) to meet all the requirements of the European ...

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...
