Thermometer

Thanks for posting,

some tips:

Learn to use arrays and loops so repeating pieces of code can be made easier:

(not tested, but it would become something like this.

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

float temp[4];
char text[4][] = { "T Int. ", "T Est. ", "T Camino ", "Controllo" };

void setup() 
{
  lcd.begin(20, 4);
}

void loop() 
{
  for (int i = 0; i< 4; i++)
  {
    temp[i] = analogRead(i) * 5.0/1024.0;
    temp[i] -= 0.592;
    temp[i] *= 100;
    lcd.setCursor(0, i);
    lcd.print (text[i]);
    lcd.print(temp[i], 1);
    lcd.print (" C");
    lcd.print((char)223);
  }

  delay(10000);
  lcd.clear();
  lcd.setCursor(0, 0);
  lcd.print ("Controllo" );
  lcd.setCursor(0, 1);
  lcd.print ("temperature casa");
  delay(500);
  lcd.clear();  

}
