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 ...

In this project, I developed an innovative hardware solution utilizing an Arduino Uno board paired with an ultrasonic sensor to create a real-time object detection system. The primary objective was to ...

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 ...

Detecting objects within a 180° range. Measuring distances using ultrasonic waves. Visualizing the results dynamically on a radar-like interface. Hardware: An ultrasonic sensor emits sound waves, ...

An Arduino-based maze-solving robot using 3 ultrasonic sensors, an L293D motor driver, and 2 DC motors. The robot detects obstacles, makes navigation decisions, and autonomously traverses mazes.

Abstract: The paper is the design and implementation of a lowcost vehicular speed detector system based on Arduino microcontroller along with the use of ultrasonic sensors. The suggested technology ...

The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears ...
