Arduino gone wireless: TP-LINK TL-WR703N

I recently bought a wired Ethernet shield to experiment internet connectivity with Arduino: the wireless shield was a bit too expensive. Then I found the TP-LINK TL-WR703N 3G router (link) on ebay (link) at less than 25$.

Triggering Pusher client events from Arduino

With Pusher service one can send push messages from a mobile app (or a web page) to an embedded system to trigger some action, such as power up some lights or open a door. The system is quite simple: the webpage registers itself to send a message that is triggered on an user action, the embedded system registers itself to receive that specific message and waits for the message to arrive on a socket. But what if we want the embedded system to answer to the web page?

New arduino project entry

I added the new arduino section in the Projects page.
