Ultrasonic sensors have become commonplace thanks in considerable measure to adoption in early-stage autonomous driving vehicles. Ultrasonic technology uses mostly inaudible sound waves (starting at ...

WORKING VIDEO: human-following-robot.mp4 Conclusion: Building a human-following robot using Arduino and three ultrasonic sensors is an exciting and rewarding project that combines programming, ...

Project description In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

Now, the venerable ultrasonic sensor joins the gallery of classics given a size change treatment, like the 555 timer we’ve seen two different takes on, or perhaps that one Arduino Uno.

Ultrasonic double-sheet detectors distinguish between single and double sheets of paper, plastic, or metal foils to prevent waste or machine damage. The sensor operates by beaming ultrasonic sound ...

That might not sound like a big deal, but let's face it — traditional embedded fingerprint sensors have gotten staggeringly fast and accurate over the years, to the point where in-display ...
