Circuit Documentation

Summary

This circuit consists of an Arduino Nano microcontroller, a Tower Pro SG90 servo motor, and a rain sensor. The Arduino Nano serves as the central control unit, interfacing with the rain sensor to detect moisture levels and controlling the servo motor based on the sensor's readings.

Code Documentation

Arduino Nano Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino Nano. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly.
