Hi.
I have an arduino ethernet which controls a relay. If I send in a browser http://192.168.1.10/relay1on, it turn on the relay and the browser return 1, if I send http://192.168.1.10/relay1off, the relay turns off and the browser return 0.
The question is how can I make a button in graphical view to turn the relay on and off?
Thanks.

It can be done with Publisher. I will come back with details.
