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 ...

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 ...

Programmable logic controllers are widely used in industrial automation systems to control machinery, monitor sensors, and manage manufacturing operations. Although PLCs provide reliable machine ...

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 ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

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 ...

Editor’s Note: When I first published this, I stated that R2 would be dropping ultrasonic sensors and moving to a vision-only setup. After going back and revisiting Rivian’s Autonomy Day presentation ...

Let’s face it: As we age, our vision and balance aren’t what they used to be. These changes to our senses can be minor annoyances but can also lead to injury, from stubbed toes to serious falls.
