arduino mega+ethernet shield+button switch+ toggle switch

Projects Programming
1

Hi all, I have a programming question. I'm a noob and i don't know how to start so please help me.

I have an arduino mega 2560 r3 an ethernet shield 5100 and a toggle switch.
I would like to drive a small 220v lamp relay output is on pin 22
In the space below i have paste my code. This code put on or off my lamp via ip/web page, but how could I add a button (on pin 13 like input) so I could read his state and update webpage state?
Maaaaany thanks in advance

This code put on or off my lamp via ip/web page, but how could I add a button (on pin 13 like input) so I could read his state and update webpage state?

You can't. The Arduino is a server. It responds to client requests. It can NOT push data to clients. The clients have to pull data.

You can add appropriate meta tags to have the page automatically refresh after a defined period of time.

I have understand that but my question is another.
I have this layout

lamp----------------relay(output)------------arduino------------------ethernet shield
|
|
button(input)

I could make a program to drive my lamp with the ethernet shield and also with the button, but How can I make this two think to work together?
Many thanks in advance

How can I make this two think to work together?

First, you define the requirements for the combined program.
Second, you write the program. If it does what you want, great. If not, I seem to recall that there is a site dedicated to getting help with Arduino questions. Can't remember the URL off the top of my head, but I'm sure that a little google fu will help you find it in no time.

hi all
is there any way about this?
thank you...

is there any way about this?

Until you define your requirements? No.
