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 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 project simulates a 2D LiDAR system using SR04 ultrasonic sensors mounted on a stepper motor. The system interacts with the Sensors through a Arduino UNO R3 and scans the surroundings, sending ...

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 ...

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.

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 ...
