If you go to arduino install directory
and then the libraries folder
then the Bridge folder
then the examples folder
then the TemperatureWebPanel folder!
Then you will see the www folder right next to the TemperatureWebPanel.ino sketch in there you will find the index.html and the zepto.min files.
Al so I had to use the url of the Yun in place of the Yun's name "192.168.1.103" in place of "ardunio" in order for the html page to come up, don't ask me why because I have no idea! Maybe someone else could answer that?
So the url would look something like this http://192.168.1.103.local/sd/TemperatureWebPanel
