If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

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 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 ...

Abstract: This paper shows non-contact water level monitoring system implemented using LabVIEW and arduino. Water depth of the tank is measured by Ultrasonic sensor. Hence the water level present in ...

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 ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

The Wireless Ultrasonic Radar described here is a scaled-down version of a true radar system. It utilises ultrasonic sound waves to detect nearby objects, presenting their precise distance (in cm) and ...
