Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a rain sensor, and a servo motor. The rain sensor detects the presence of rain and sends an analog signal to the Arduino. Based on this signal, the Arduino can control the servo motor to perform a specific action, such as closing a window or activating a cover.
