This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

This project demonstrates a line-following robot built using an Arduino Uno, IR sensors, DC motors, and an ultrasonic sensor. The robot can detect and follow a black line on a white surface and avoid ...

The following image shows the circuit diagram of the Smart Dustbin with Arduino. It is a very simple design as the project involves only three main components (Ultrasonic sensor, IR sensor and Servo ...

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 ...

What is an Arduino Obstacle Avoiding Car? An Arduino obstacle avoiding car is an autonomous mobile robot that's designed to identify obstacles that are in its way and make decisions to navigate around ...

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 ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...
