Use the simple html below to retrieve your data from thingspeak into one page, simple example of multiple channel and multiple sensor data......
Freeboard and other links also in the html edit to your setup.......then use it in your sketch for the device......do something useful with the JSON Frame............(See my other post on stripping data from webpages).....
Even Simpler way.....
This will import the tweet to your sketch just embed the html....
