Server on the Public Internet Again
The olduino server is back online at http://126.96.36.199:1802
The obvious change is that instead of reporting the LED status with text it shows an animated picture of the board with the LED either on or off. All I had to do was change the text I sent out from “The LED is ON” to a HTML img tag and your browser does the hard part of fetching the picture and displaying it.
Under the covers the big change is that it pays attention to the IP of an incoming request. If it hasn’t seen a particular IP before it invites you to tell it your name or where you are. It displays a rolling list of the last 32 contacts. I originally thought I would have some kind of multi-player game but I couldn’t think of one.
