chciałem zrobić sterowanie przekaźnikami oraz odczyt z kilku czujników przez internet.
Użyłem do tego Arduino Leonardo oraz rutera Huawei B683.
Problem polega na tym, że serwer jest niestabilny, czasem się wyłączony, czasem przytnie itp.
Dodam, że WebSerwer z przykładu Arduino działa bez zarzutu.
Mam jeszcze problem ze sterowaniem z przekaźnikiem.
Mianowicie gdy przerzucam z Off na On wszystko jest ok. Problem pojawia się, gdy przełączam z On na Off. Pierwszy raz gdy klikam On na Off nic się nie dzieje, dopiero za drugim razie przeskakuje na Off. Gdzie może być przyczyna?
