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.

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

Build your own interactive laser chasing toy for your dog using Arduino! In this DIY project, we use simple components like a laser module, servos, and motion logic to create a fun, automated game ...

[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… ...

To generate these signals, I used an Arduino. One of the greatest challenges of the project was creating an analog output that was fast enough to move the galvo (and laser beam) so that it ...

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 ...

How to build a laser trip wire alarm with Arduino As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to ...

Horizontal Laser Harp makes sweet music There's something about a Laser Harp that gets my attention. Make it horizontal and you have a further twist. Yes, Laser Harps are apparently a Thing - when the ...
