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 ...

1 Arduino Ultrasonic Sensor (HC-SR04) 1 buzzer; Ultrasonic sensor, mounting circuit; It is a very simple circuit. On the one hand, we will have all the alerts, acoustic and visual, and on the other ...

Ultrasonic sensor that measures the distance and the LED’s bar graph will light up according to our distance from the sensor and as we get closer the buzzer beeps in a different way. This circuit can ...

Here is a simple 3 Ultrasonic sensor-based Human following robot using Arduino Uno code that you can use for your project. This code reads the distances from three ultrasonic sensors (‘frontDistance’, ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

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 collaboration of ...
