Have you looked at any of the supplied examples?

It can be a webserver (the webpages could be on the microSD card, and the webpages can be combined with HTML5 and AJAX), and a client that visits websites (or to upload to ThingSpeak.com), and also UDP communication, like requesting the time (NTP uses UDP). This can all be combined in a sketch.

Start with the example that shows a single webpage.

How would you want to send and receive data ?
