Arduino uno and Ethernet shield

[Luckyman]

Hi sir, If I want to use Arduino uno and Ethernet shield, do I have to modify code? And how do I wiring relay and board?
Thank

Code should work as-is without changes, even when using a Uno. You might want to check at our
older instructions PDF which uses hardware which is somewhat closer to your setup. The links to
our previous versions of the instructions PDF can be found in the current version of the PDF,
in the Intro if I recall ...
