def light_control():
    global count  # It's for update count variable globally
    keyboard = Controller()
    # Wait for 0.5 sec.
    time.sleep(0.5)

    # This part checks capslock is on or off
    DISPLAY = display.Display()
    keyb = DISPLAY.get_keyboard_control()
    DATA = keyb._data
    led = DATA['led_mask']
    caps= (led & 1) == 1  #(caps:bool) type

    if count < 20:
        if caps:  # if caps == 1, caps is ON
