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 ...

A dynamic traffic control system that operates based on "traffic density" on intersection lanes / junctions to dynamically manage traffic. Using an interrupt-driven approach, the Ultrasonic sensors ...

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 ...

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 ...

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 ...
