Hi can someone please help me not sure what i`m missing just cant get the status of the pin next to the buttons nearly there tho thanks
#include <SPI.h>

byte gateway[] = { 192, 168, 1, 254 }; //Routers IP Address to which your shield is connected.
byte subnet[] = { 255, 255, 255, 0 }; //It will be as it is in most of the cases

const int shed_lock_relay = 7; //shed lock relay set on pin 7
// variables will change
