A collection of beginner-to-intermediate Arduino, ESP8266, and sensor projects — LCD displays, ultrasonic and IR sensing, I2C peripherals, and simple automation — built and documented as part of The ...

Every major smart ring on the market today made the same design choice: no screen. Oura stripped it. Samsung stripped it. Virtually every competitor that followed stripped it. The implicit industry ...

Why passive ultrasonic offers a unique option of sensing discrete open/close events. How a team used passive, non-electronic metal tag for signal initialization. How they used DSP-based, non-ML, ...

The **HC-SR04 Ultrasonic Distance Sensor** is one of the most popular distance measurement modules used in Arduino, ESP32, robotics, and IoT projects. It measures the distance between the sensor and ...

If you’re unfamiliar, board-certified dermatologist Michele Green, MD, describes them as handheld devices that use high-frequency vibrations, typically between 20,000 and 30,000 hertz, to exfoliate ...

Sonair’s ADAR One 3D ultrasonic sensor provides spatial awareness for robotic systems, enabling detection of people and obstacles across multiple heights in shared work environments. Sonair has ...

Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether you want to measure ...

Looking ahead: Midjourney built its name on AI-generated images. Now, it is talking about something far more ambitious: scanning the human body. In a post this week, the company outlined plans for a ...

Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using only sound. Without electricity, electronics, or batteries. The sensors are ...

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 ...

This project uses an ultrasonic sensor to detect distance and display it on an OLED Display with an Arduino Mega microcontroller. Triggering: The Arduino sends a short electrical pulse to the ...
