1. The **HC-SR04** emits ultrasonic waves and measures the time it takes for them to bounce back. 2. The **Arduino Nano** calculates the distance using the speed of sound. 3. If an object is detected ...

For an ultrasonic anemometer to work ... Inside the light is an Arduino Nano, which reads from the ultrasonic sensor mounted underneath ... is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, ...

This project demonstrates a basic implementation of a ball-and-beam balancing system using Arduino NANO, ultrasonic sensor sr04 , L298N Motor Driver and a motor. The system uses manual control logic ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...
