Lasers are some of the coolest devices around. 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-… ...

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 ...

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 ...

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. Patrick ...

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 ...

It’s a fairly simple circuit — just push the momentary switch, and the laser diode and sensor pair count the revolutions over one second. The Arduino Nano multiplies this number by 60 and ...

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 ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
