Project Overview: This project involves creating a functional radar system using an ultrasonic sensor, Arduino Uno, and a breadboard. The radar is capable of detecting objects within a specified range ...

The driver exploits the fact that, at resonance, current and voltage is in phase for a piezoelectric transducer. By locking the driving signal to the current feedback signal, i.e. adjust the driving ...

November 15, 2025 • On October 1, 2025, public radio stations lost all of their federal funding -- and for Black and Native American community stations, the cuts hit hard. Case in point, KYUK in ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (November 2025) that make the cut: ...

Abstract: In a typical introductory programming course, grading of student submitted programs is often done manually by examining the source code prior to assigning the final grade for reasons such as ...

Abstract: Urban flooding remains a critical challenge, exacerbated by inadequate drainage systems and the lack of timely early warning mechanisms. This paper presents a sustainable urban flood ...

Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well as to measure fluid flow rates in industrial and scientific applications.

A programming language is a set of symbols whose strings are governed by rules apt to communicate instructions to a particular machine. Such strings may be concatenated into longer code and implement ...
