Program ma za zadanie pokazywać na wyświetlaczu zmierzone parametry (dwie temperatury, wilgotność i ciśnienie, czas i datę) oraz włączać oświetlenie przez sterowanie przekaźnikiem pin 6. Pytanie czy pin 6 nie będzie się z czymś gryzł np z wyświetlaczem? Po włączeniu przekaźnika przez piny 9 i 10 (PWM) ma przez zadany czas "rozjaśniać" ledy, następnie przez zadany czas świecić z pełną mocą aż do zadanego czasu "ściemniania" na koniec ma zostać wyłączony przekaźnik na kanale 6 Czas jest liczony dla każdego kroku (włączenie, rozjaśnianie, świecenie, ściemnianie, wyłączenie) odliczając sekundy od północy. Problem mam z wyświetlaczem, nie wiem czy tak poskładany program będzie dobrze wyświetlał informacje na zmieniających się stronach na LCD i czy będzie poprawnie działał.
