Powered by an Arduino Uno, this laser tripwire alarm project works much like those in movies. There's a tripwire — made up of a laser directed at a light sensor — that's placed somewhere the ...

LiDAR technology utilizes laser light to measure distance to objects and terrain. Many of these sensor systems, such as Quanergy's solid-state unit for self-driving cars , can cost upwards of US ...

Makers, Arduino and electronics enthusiasts that have wanted to create a laser sky effect generator, may be interested in this new DIY tutorial which is being published by YouTuber “Normal ...

4. Connect the breadboard rails to Arduino GND and +5V, and then check that your setup matches that of Figure 10-3. Mounting the Laser. For this project, I’ve attached the servos to a pan-and ...

He has a very nice $290 laser particle counter, but was really curious how the $12 sharp sensor he found would stack up. To find out, he plugged it into an arduino and started logging both on pachube.

It would be interesting to see a laser-based sensor paired with this code. Posted in Arduino Hacks Tagged 3d scanner , arduino , sharp GP2D120X Post navigation ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

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 ...

Jon Bumstead has created an awesome Arduino powered 13 note midi harp after receiving funding from the optics group Spectra at Washington University. ... This laser harp has thirteen strings.
