Summary

This circuit is designed to interface an Arduino Nano with a rain/snow sensor, a DC motor, and a motor driver. The Arduino Nano reads data from the rain/snow sensor and controls the DC motor through the L298N motor driver. The circuit is powered by a 9V battery.

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 you place the main logic that runs repeatedly.
