Arduino – Ethernet Switching

Cały projekt miał za zadanie umożliwić sterowanie przekaźnikami z wykorzystaniem sieci Ethernet docelowo możliwość sterowanie przez internet. Wszystko z wykorzystaniem schludnego interfejsu www. Dzięki czemu możemy sterować całością z telefonu, tabletu czy standardowego PC.

Do wykonania będą nam potrzebne następujące elementy:

– Arduino Mega (lub odpowiednik),
– Modułu ethernet ENC28J60,
– Moduł 8 przekaźnikowy x 2,
– Przewody połączeniowe. 

Połączenie przewodów:
