HELP REVIEW MY ARDUINO UNO SKETCH FOR A MONITOR USING LM35 AND KY039

TolpuddleSartre:

digitalWrite(LED, LOW);

if(cel <= 39)
  {
    digitalWrite(LED,LOW); //switch LED off
  }


Pretty pointless conditional.

Thanks!
So apart from the delays, will the LCD print both temperature and heart rate simultaneously from the way i've structured the sketch?
Or will it display both values one after the other?

Does me placing the lcd.print statement at each different loop mean they'll be displayed one after the other? Or should I place all the lcd.print statements altogether?
