Witam wszystkich.
Jestem tutaj nowy na forum i to mój pierwszy post.

W skrócie ….
Mam Arduino Uno,zmontowałem układ by sprawdzić wyświetlacz 16x2.np "Hello World"
Uruchamiam Arduino wer 1.6.12 podłączam arduino wyszukuje z biblioteki Liquidcrystal…Hello World.
Naciskam zweryfikuj i otrzymuje komunikat:

Błąd kompilacji dla płytki Arduino/Genuino Uno.

Nie wiem o co KAMAN i proszę o pomoc.Dodam że wcześniej nie korzystałem z Arduino.
Komunikaty które ładuje Arduino sa takie same na 2 laptopach System operacyjny Win 10 i OS X 10.7.

Port USB wykrywa Arduino.

Dziękuje za sugestie.
