IntroductionMany people feel that electronics and robot control are daunting because they require hardware knowledge and coding skills. In this project, I experimentally progressed from 1. basic GPIO ...

Dolphins can find their way through dark, murky water by listening to echoes. Inspired by this ability, researchers in South ...

Run AI locally using devices ranging from an ESP32S3 chip to an RTX 4090 GPU. Match your hardware bandwidth and capacity to ...

So, if the pin layouts on a tutorial don’t match the ones I’ve got on my ESP32, I’d look at what protocol the sensor uses, go ...

What is a Quality Assurance Project Plan (QAPP)? A QAPP is a written document that explains how organizations ensure – using quality assurance (QA) and quality control (QC) activities – that the data ...

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 ...

Researchers have demonstrated they can make coffee comparable to conventional espresso using ultrasonic waves. Because the process doesn’t need hot water, it consumes 75 percent less energy. The ...

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 ...
