온도센서 + LCD

온도를 읽어 LCD에 출력해 온도계를 만들어보자.!

#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

float temperature;  
int reading;  
int lm35Pin = 5;

void setup()  
{
    analogReference(INTERNAL);
    Serial.begin(9600);
}

void loop()  
{
    reading = analogRead(lm35Pin);
    temperature = reading / 9.31;
    Serial.println(temperature);
        lcd.begin(16, 2);

    lcd.setCursor(0, 0);

    lcd.print(temperature);
    delay(1000);

}

짜잔-
