Thank you for your reply.
After 10 seconds LED(pin) turns off to LOW. If you don't press button any more - all LEDs are off. For example, button has been clicked already 3 times and all LEDs are off, if I click button again, pin 4 goes HIGH for 10 seconds and then turns off again. Loop starts again, when pin 13 has been HIGH for 10 seconds.
I hope you understand.
