Server-Sent Events / EventSource Demo

This demonstrates how to use EventSource with PHP or Arduino Event Generators.

Here's a small explanation and a video demo of the scripts:

Arduino

Use an Arduino Ethernet or the Ethernet Shield with any other Arduino board. Add Something to pins 5, 6 or A0. Enter a free IP in the .ino file on which your Arduino will be available.

Alter the IP in index.html to match your Arduino's IP.

PHP

Change the script in index.html to point to source.php - the code is already there, you just need to remove a comment.

Run php -S 0.0.0.0:8000 in this directory, this will create a simple webserver.
