Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, an HC-SR04 Ultrasonic Sensor, and a Servo motor. The Arduino UNO serves as the central controller, interfacing with the ultrasonic sensor to measure distance and controlling the servo motor based on the sensor's readings.
