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 ...

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 ...
