This project simulates a 2D LiDAR system using SR04 ultrasonic sensors mounted on a stepper motor. The system is controlled by an Arduino UNO (Elegoo R3) and scans the surroundings, sending distance ...

The code of my 2017 sumo robot, using an arduino nano, two HC-SR04 ultrasonic sensors, two TCS3200 color sensors and a L298N motor controller.

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

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 ...
