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 project, we create a joystick-controlled laser by connecting two servos to ... The following is excerpted from the book Arduino Project Handbook: 25 Practical Projects to Get You Started ...

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 ...

What if you want to take it to the next level? In that case, [Electronoobs] has an Arduino powered RC transmitter with your name on it. But this is no scrap of protoboard with a couple of cheap ...

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 ...

Both of the freestanding modules (NS73MFM transmitter, Arduino UNO) can be mounted to a breadboard and interconnected. Refer to the hardware setup and proceed. The simple code generates digital tones ...

Instructables member Patrick Panikulam has created a versatile wireless Arduino pen plotter and laser engraver, powered by an Arduino UNO microcontroller and offering a work area of 200 x 162 mm ...

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 create a simple laser trip wire alarm. You've probably ...
