Summary

This circuit integrates an HC-SR04 Ultrasonic Distance Sensor with an Arduino UNO microcontroller and a buzzer. The HC-SR04 sensor is used to measure distances by emitting ultrasonic waves and receiving the echo. The Arduino UNO processes the distance information and controls the buzzer accordingly. The buzzer serves as an output device that can provide audible feedback based on the sensor's readings.
