Hi,
Right now I have a really simple HTML-page running a PHP script that fetches some data from another website and displays it. Really simple.
Now I want to take it to the next level and use the data with an Arduino Yun, but before I get going I would like to know if I am on the right path.
My idea is to:
1: Make a simple HTML-page with PHP scripts as a user interface. This page should run on the Linux side of the Yun and will only be accessed by the user from the local network. I use PHP because I am familiar with it, and because it can run on several devices. Can the user easily access this page as was it on a normal web server? Do I need a SD card for this?
2: The Linux side will send data to the Arduino side using Bridge. Simple calls to local.arduino seems easy and fast.
3: The Arduino side will, if instructed, call a php script that fetches data from another website in an arbitrary interval. This script will return data using Bridge.
I know this is kind of a big question, but I could really use some input before starting, as it is a big project for me and my still limited programming skills 
Thank you!
