A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

Test the functionality of sensors and motors before integrating with Arduino using these standalone test codes. Ensure each component works as expected, simplifying debugging and setup for your ...

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

Forget keys! The top smart locks we've tested are secure, easy to install, and provide several convenient ways to control who can access your home and when. I'm PCMag's managing editor for consumer ...
