INPUT_PULLUP - INPUT z podciągniętym wewnętrznie rezystorem żeby się pozbyć stanu pływającego np do przycisków, zamiast tego rezystora do gnd, ale czasem se działą czasem se nie działa, czy mu ufac idk elektronika be weird and untrustworthy 🤷

pulseIn do czytania impulsu np z ultrasonicznego typiarza https://www.arduino.cc/reference/pl/language/functions/advanced-io/pulsein/

waits for the pin to go from LOW to HIGH starts timing, then waits for the pin to go LOW and stops timing.albo w druga strone w zaleznosci od podanego paarmetru.

Works on pulses from 10 microseconds to 3 minutes in length.
