Arduino + Ethernet Shield Traffic Light (do I have internet?)

Whenever it rains in the city, there are always areas that lose internet connectivity, and my office is one of them. This traffic light sends out ICMP pings to see if it is connected and changes lights appropriately.

Parts needed:
Arduino Uno R3 or any Arduino, really
Ethernet Shield
Traffic Light Lamp, available on Amazon or at Walmart
3 15 Ohm Resistors
