Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with a Soil Moisture Module and a buzzer. The Arduino UNO is used as the central processing unit, interfacing with the Soil Moisture Module to read moisture levels and controlling the buzzer based on certain conditions. The Soil Moisture Module provides both analog and digital signals representing the moisture level of the soil, which can be read by the Arduino. The buzzer is used as an output device to alert or indicate certain moisture conditions.
