Jon,
Let me first off say you are putting out some amazing how-to's! I love the work you're doing and plan on getting into the home automation for fun. I have very limited experience with any of this so my issue is more than likely self induced. When I copy your sketch and paste it into Arduino IDE, I get the above error message. Any help would be great
Board type: UNO V3
Ethernet Shield: Sunfounder
sketch_jan07a.ino:7:23: fatal error: WebServer.h: No such file or directory
compilation terminated.
