This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

We decided to use ... with an Arduino boot loader was used to perform calculations and control the sensor (HC-SR04) and actuator (SG90 mini gear). The robot has two independent wheels, driven by ...

Researchers create a flexible ultrasonic device enabling wireless charging underwater and inside the human body.

A research team from KIST and Korea University has developed a biocompatible ultrasonic receiver. As demand grows for ...

Abstract: An ultrasonic distance measurement system for use in air is presented. The measurement is based upon the two-frequency continuous-wave (TFCW) phase-shift method. In the system, two vernier ...
