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.

Here’s the version of his laser engraver” DIY laser engraver components list : – Arduino Nano – 250mW 650nm Laser Module – A4988 Motor Driver – IRFZ44N Mosfet – LM7805 Voltage Regulator.

[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… ...

We can use them to cut things, create laser light shows, and also as a rangefinder. [Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on creating an Arduino based laser rangefinder.

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 ...

Dubbed the “Cat Laser Tower”, the build consists of two servos to move the laser about, some 3D printed housings to hold them and provide pivot points, a small laser and an Arduino to make ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.
