hello.
i'm new to the arduino but i have some basic knowledge with C,C++
i bought the nano & ethernet shield and board with 4 relays.
(i will use it as NC)
i want to check every X time if i've got a conection to the internet.
if yes - good dont do nothing
if not - send several alive test to the internt.
- if no conection- open the relay for X seconds and close it again.
i'm looking for some direction or tutorial for the ethernet shild
and ping examples.
thank you 
ge_va.
