Typically, a beam interruption application has the laser receiver and transmitter pair always on, and the MCU code (on an Arduino, for example) in the loop () polls a pin attached to the output of the ...

The sensor uses a laser diode and a photodiode to detect and count particles, while a fan moves air through the system.

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

High sensitivity, very low power radiation sensor in a Arduino shield form factor. Like many other hobbyist I have always been fascinated by radioactivity and the sensors to detect it.Geiger-Müller ...

Laser Blaster Last Updated: 7/27/18 Teaching Standard: 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 ...

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 ...

In this project, we will interface a Pulse Sensor with an Arduino to measure heart rate (Beats Per Minute - BPM), with the results displayed on an OLED display instead of a traditional 16×2 LCD. The ...
