Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...

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 ...

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 ...
