Summary of the Circuit

This circuit integrates an Arduino UNO microcontroller with an HC-SR04 Ultrasonic Sensor and a Buzzer. The Arduino UNO is used as the central processing unit to control the sensor and the buzzer. The HC-SR04 Ultrasonic Sensor is connected to the Arduino to measure distances by emitting ultrasonic waves and receiving the echo. The Buzzer is used to provide an audible alert based on the sensor readings. The circuit is powered by the 5V output from the Arduino UNO.
