Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a Tower Pro SG90 servo motor, and an Ultrasonic Sensor. The Arduino UNO serves as the central control unit, interfacing with the servo motor and the ultrasonic sensor to perform various tasks. The ultrasonic sensor is used to measure distance, and the servo motor can be controlled to move based on the sensor's readings.
