Gesture control robotics replaces traditional buttons and joysticks with natural hand movements. This approach improves user ...

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 ...

This project demonstrates how to interface an HC-SR04 ultrasonic distance sensor with an SSD1306 OLED display using the STM32 Blue Pill microcontroller. The system measures distances and displays them ...

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 video I'm walking you through the steps I took to make a standalone version of my pellet level monitoring sensor that ...

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

I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless ...

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching ...

A quantum net for dark matter: A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things ...
