There are quite a few ways to get data from your Arduino onto the internet, but I especially like this one. Open Electronics has a nice tutorial on using your Arduino to send data to be saved into a Google Spreadsheet. The trick is to use Google Spreadsheet’s form input feature to determine its POST URL for adding data points. I like this method not only because your data is immediately accessible anywhere you have access to Google Docs, but also it can easily be evaluated, graphed, and shared right from within Google Docs.
