Within the 20 seconds the buttonpresses will be measured. Per 10 clicks, one light on the LEDstrip will go on. 10 lights in total.

• capture timestamp on 1st button press
• check if time expired in loop(). reset when expired
• check for button press in loop(), count button presses
• number of leds lit = number of button presses / 10
• stop if number leds == 10 before time expired
