🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs 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 ...

The Arduino code performs the following tasks: Sweeps the servo from 0° to 180° and back. At each angle, it triggers the ultrasonic sensor to measure distance. Depending on the measured distance: ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need … ...
