I found this brilliant code on the forum which has different kind of buttons, but when i add more buttons it dosen't work properly(as in two three relays turn on/off at the same time) i was wondering if anyone can tell me how to add more buttons for relays, i dont mind using an sd card also if u can just show me how to extract the get request to turn on/off the relays
THanks a lot!
Here's the code
//zoomkat 8-04-12
//simple button GET server code to control servo and arduino pins 5, 6, and 7
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use ' instead of " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
///note that the below bug fix may be required
// http://code.google.com/p/arduino/issues/detail?id=605

byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
