Two button two option

In practice he reads the voltage that passes between the buttons and based on what is pressed Arduino reads the voltage and determines which button was pressed through a very simple IF:

the buttons connect different size resistors to a voltage divider where the voltage is measured using a single pin. i've seen this on vacuum cleaners

don't you have buttons connected to separate pins?

  //Btn1 = 8, Btn2 = 12
  while(digitalRead(8) == LOW && digitalRead(12) == LOW){
    Btn1Stato = digitalRead(Btn1);
    Btn2Stato = digitalRead(Btn2);
