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 ...

We know everything produces sound wave just by existence and effect flow of air around them with their natural frequency. These frequencies are beyond hearing range of humans. Wave of frequency range ...

Abstract: The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the ...
