Display data from a networked Arduino with only a web browser

Arduino enthusiast Luca Dentella has published another interesting Arduino tutorial, and in this edition he demonstrates another method of displaying data captured by an Ethernet-enabled Arduino using a webpage. There is a little more to it, and this involves a HTML page with access to JavaScript and CSS files. Using two open-source libraries the project allows JavaScript code in the HTML page to send JSONP requests to the Arduino, which responds in turn with a JSON message that contains the values obtained from a DHT22 temperature/humidity sensor connected to the Arduino. The data is then displayed in the web browser in graphical form. 

For all the details, visit Luca's tutorial. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

When putting together your next Internet-enabled Arduino project - save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
