Hello,
I would like to combine these two projects.
When a button is pressed the LCD display changes from "Visitor counter" and displays "temperature", and when the button is reset it returns to "Visitor counter".I
f you can help me. It is only now that I have started using Arduino.
Thank you.
#include<LiquidCrystal.h>

{

lcd.clear();
lcd.print("Person In Room:");
lcd.setCursor(0,1);
lcd.print(count);
