Summary

This circuit integrates various components with an Arduino UNO microcontroller to perform a set of functions. The circuit includes a rain sensor, a water sensor, a micro servo, a buzzer, a resistor, and an LED. The Arduino UNO serves as the central processing unit, interfacing with the sensors to detect environmental conditions, controlling the servo, and providing visual and auditory feedback through the LED and buzzer.

Additional Notes

• The provided code is a template and does not include specific functionality. It needs to be populated with the logic to read sensors, control the servo, and activate the buzzer and LED based on sensor inputs.
• The setup() function is intended for initialization code that runs once, such as setting pin modes.
• The loop() function is for code that runs continuously, which will include the main logic of the circuit's operation.
