In my first Instructable "Getting Arduino data to a web page" I talked about refreshing the data by using the Meta command to refresh the My SQL data content.

The problem with this is that it refreshes the entire page and could possibly interfere with other scripts as well. So I have made a couple of improvements that might just make things work together a little more smoothly.

We then submit the request by changing the URL of the hidden frame.
