after opening the serial monitor, you should see different values printed on a line and refreshed very quickly. these are the state of the various buttons present on the joystick shield, as well as the
.current position (x and y value) of the joystick

// Select button is triggered when joystick is pressed

const byte PIN_BUTTON_F = 7;
