/*
  Reads an analog input on pin 0, prints the result to the Serial Monitor.
  Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

  This example code is in the public domain.

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  lcd.begin(16,2);
    lcd.backlight();
    lcd.setCursor(0, 0);
   // lcd.print("Hello world!");
    lcd.setCursor(0, 1);
  //  lcd.print("Row number: ");
    lcd.setCursor(12, 1);
//    lcd.print("2");
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  int sensorValue1 = analogRead(A1);
  int sensorValue2 = analogRead(A2);
  
  float temp1 = sensorValue * (62.0/1023.0);

  float temp =(average/3);
 
  // print out the value you read:
  Serial.print("sensor =");

  Serial.print("temp =");
  Serial.println(temp);
  Serial.println(  );
  lcd.clear();
  lcd.print("Temp = ");

   lcd.print(" 0C");
  delay(1000);        // delay in between reads for stability
