Obstacle Detector and Distance Measurement System This Arduino project utilizes a Passive Infrared (PIR) sensor to detect the presence of obstacles and an ultrasonic sensor to measure the distance to ...

This project demonstrates how to use an ultrasonic sensor to measure distance from objects and display the result on a 16x2 LCD screen using an Arduino board. Ultrasonic sensors are commonly used for ...

This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects via measuring the internal heated chip temperature with 0.01 ...

Reader [Joshua] sent in his latest project. using a sonar rangefinder, an Arduino, and some clever programming, he’s made is computer react to his distance from it. As you can see in the vide… ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well… ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...
