This project involves developing a simple application using an Arduino and an ultrasonic sensor to measure the speed of an object. The application will calculate the speed based on the time taken for ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

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: Road safety is a concern of all authorities. One of the most important safety concerns is excessive speed which results in accidents, injuries, death, as well as damage in public property.

Abstract: In previous times, the task of cutting or mowing grass required a significant amount of time and exertion. The introduction of a novel breed of mowing equipment significantly facilitated the ...
