I need some help to configure a HTML button. This button serve to control a LED with the Ethernet Sheild.
I started with that :
cl.println("<input type=\"button\" name=\"BT\" value=\"Ouverture\" onclick=\"submit();\">");
I don't know how to have a resquest.
Thanks for help.
Server test code with buttons.
//zoomkat 3-17-12
//simple button GET server code to control servo and arduino pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
//Powering a servo from the arduino usually DOES NOT WORK.
//note that the below bug fix may be required

I use ethernet sheild, and I want to use button like this example :
for control LED.

Start you dev : focus développement et programmation
for control LED.
There seems to be several examples there. Which one are you talking about?
