Circuit Documentation

Summary

The circuit in question consists of an Arduino UNO microcontroller interfaced with an HC-SR04 Ultrasonic Distance Sensor and a Servomotor SG90. The Arduino UNO is responsible for controlling the servomotor based on the distance measurements obtained from the ultrasonic sensor. The sensor triggers ultrasonic pulses and receives the echo to determine the distance to an object. The servomotor adjusts its position accordingly, as instructed by the Arduino UNO.
