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 ...

Abstract: In environments where visual sensors falter, in-air sonar provides a reliable alternative for autonomous systems. While previous research has successfully classified individual acoustic ...
