Tutorial-interfacing-ultrasonic-sensor-with-arduino A small tutorial for interfacing a ultrasonic sensor with arduino this uses a sensor called HC-SR04 which sends ultrasonic waves to detect objects ...

It emits an ultrasound at 40 000 Hz which travels through the air and if there is an object or obstacle on its path It will bounce back to the module. Considering the travel time and the speed of the ...

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 ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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.

This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve obstacle ...
