Web Control Relay - Arduino
Using the same hardware and an ethernet sheild I found and modified an ethernet sketch to control the relays. This sketh controls each rely with a specific URL. I have the IP set to 192.168.1.111. The URL for pin 2 is 192.168.1.111/$1 and 192.168.1.111/$2 to toggle it on or off.pin3 is $3 and $4pin4 is $5 and $6pin5 is $7 and $8pin6 is $9 and $0
pin7 is $A and $Bpin8 is $C and $Dpin9 is $E and $F
I didn't write this sketch. I just made a few mods. All credit goes to the original author.
/* Web Server Demo thrown together by Randy Sarafan
Allows you to turn on and off an LED by entering different urls.
To turn it on:http://your-IP-address/$1
To turn it off:http://your-IP-address/$2
Circuit:* Ethernet shield attached to pins 10, 11, 12, 13* Connect an LED to pin D2 and put it in series with a 220 ohm resistor to ground
