Rainfall Measured Using Arduino

//Rainfall Measured Arduino Code:

#include <LiquidCrystal.h>
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
void setup () {
// initialize serial communication at 9600 bits per second:
Serial.begin (9600);}
void loop() {
// read the input on analog pin 0:
int value = analogRead(A0);
lcd.setCursor(0, 7);
if (value > 500) {
Serial.println("Very heavy Rain");
lcd.print("Very heavy rain");}
else if ((value > 300) && (value <= 500)) {
Serial.println("AVERAGE Rain");
lcd.print("Average Rain");
lcd.print(" "); }
else{
Serial.println("Dry Weather");
lcd.print("Dry Wather");
lcd.print(" ");}
delay(100);}
