Circuit Documentation

Summary

This circuit integrates multiple HC-SR04 Ultrasonic Sensors with an Arduino UNO microcontroller. The HC-SR04 sensors are used for distance measurement by emitting an ultrasonic wave and measuring the time it takes for the echo to return. The Arduino UNO serves as the central processing unit, controlling the trigger and reading the echo signals from each sensor. The circuit is designed to provide a platform for applications such as object detection, proximity sensing, or distance measurement in various projects.
