well i there is no change in code, just schematic need to be changed..

connect one end of relay to power and the one at which LED is connected, change it drive a transistor, and transistor will be swiching relay.

you can use 2N2222 for this purpose.

there maybe some logic change needed for activating the relay. so you can check that later..
