This project demonstrates how to use the HC-SR04 ultrasonic sensor with an Arduino to measure distances. The sonar sensor sends out an ultrasonic pulse and measures the time it takes for the echo to ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay ...

This is set up for a ultra-sonic sensor (HCSR04 ultrasonic sensor), in which the sonar scans the area and when a something is detected the sonar will complete is cycle and specifically scan or track ...

If you have a good sense of balance, you can ride a unicycle or get on TV doing tricks with ladders. We don’t know if [Hanna Yatco] has a good sense of balance or not, but we do know her Arduino does.

Abstract: The Arduino-controlled radar systems constituting the fundamental elements of this RADAR system, an ultrasonic sensor and servo motor are employed. The fundamental operation of the system is ...

If you live in a relatively dry climate, you probably don't worry about underwater hazards during the flood season. If you attend Tsukuba University, Japan however -- just miles from where the ...

Two Japanese PhD candidates, Aisen Carolina Chacin and Takeshi Ozu, from the Tsukuba University have recently developed a 3D-printed sonar glove that can detect underwater items. The haptic sonar ...

A pair of Ph.D. candidates in Japan have developed a glove that lets wearers "feel" distant objects underwater, even without making physical contact. Dubbed "IrukaTact," the glove uses a combination ...
