Adruino 14 segment LED board
Introduction
For HAR2009 we build a 14 segment board (max to use on Arduino). It's called Blinky
The board was able to retrieve messages from http://www.randomdata.nl/blinky/ and display the letters piece by piece.
There is still a log of all the messages but the board is now down, probably we will use it on other conference like Brucon
Also the ETH0 winterevent had some company from blinky.
The board and the build

The Arduino code
Don't look at my programming skills, it works but it can use some adjustments :-)
