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 ...

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 ...

If you’re interested in building your own laser sky effect generator, you’ll need a few key components: an Arduino Uno, a laser module, mirrors, motors to spin the mirrors, a photoresistor, an ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

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 ...

Laser Timer Ramp Last Updated: 7/27/18. Teaching Standards: This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for ...
