When you set the mode to INPUT_PULLUP, an internal resistor – inside the Arduino board – will be set between the digital pin 4 and VCC (5V). This resistor – value estimated between 20k and 50k Ohm – will make sure the state stays HIGH. When you press the button, the states becomes LOW. microsoft teams im browser
