>Suddenly occurred to me that if I can control one of the onboard LEDs of the Raspberry Pi, I should be able to get it to “tap” out the IP address of the Pi, which would be a great help when accessing it remotely. Might even be able to tap out some status messages… might need two LEDs to do that, but might still be able to do something cool. Hmmm… Web interface… \ud83d\ude42<\/p>\n

So, did a quick search and this post on the Foundation site came up:
