Learn how to make a touchless air drum set using Arduino and ultrasonic sensors for endless musical fun. ‘That Has Never Been ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

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

In electronics, a Norton amplifier—also known as a current differencing amplifier (CDA)—is a specialized analog circuit that ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Abstract: An exceptionally sensitive and photothermally tunable polymer microbubble is fabricated at the fiber tip for enhanced ultrasonic detection. A modified acrylate adhesive (MAA) is applied to ...

Blind Spot Management System or BSMS is an IoT-based parking safety project built to help drivers and lot controllers detect blind spot risks in real time. Drivers often cannot see around sharp turns ...

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 ...
