The two buttons are used with INPUT_PULLUP mode, when the button is pressed, the LOW (0) value is read from the relevant pin, and when the button is released, the HIGH (1) value is read. This status determines whether the button is pressed or not. These read values are written to two different LEDs, causing the LEDs to blink according to the button status.
