This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

The code for this project is written in the Arduino programming language (based on C/C++). It uses the digitalWrite() function to control the state of the LEDs connected to the Arduino pins. 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 ...
