LCD_Thermometer

Arduino
Makes use of both the LCD and temperature sensor libraries (MCP9808).
#include <Adafruit_MCP9808.h>
#include <LiquidCrystal.h>
#include <Wire.h>

Adafruit_MCP9808 tempsensor = Adafruit_MCP9808();
LiquidCrystal lcd(1,2,4,5,6,7);

void setup() {
  if (!tempsensor.begin()) {
    while (1);
  }
  lcd.begin(16,2);  
  lcd.setCursor(0,0);
}
void loop() {
  float c = tempsensor.readTempC();
  float f = c * 9.0 / 5.0 + 32;
  
  lcd.setCursor(4,0);
  lcd.print(f);
  lcd.print(" F");
 
  lcd.setCursor(4,1);
  lcd.print(c);
  lcd.print(" C");
  
  delay(1000);
  lcd.clear();
