*NEW* The How to video http://youtu.be/Q9_2QDnT3Hs
This is a work in progress of my summer project. It uses an Arduino Mega 2560, an official WiFi shield, the MicroSD reader on the WiFi shield and a 300 RGB LED WS2811 strip. It accesses information from my web server such as time and weather conditions via the World Weather Online api.
Future implementations include creating an online database to send messages from any web enabled device, which can then be read on the display. Twitter feeds might gone on and Facebook notifcations could be handy. I'll be creating some weather icons so it's current and future weather, rather than just the current temperature.
Happy to share knowledge and I'll get around to writing this all up. There's been a lot of issues such as the WiFi unfriendly Arduino 1.0.5 IDE (Use 1.0.2), running out of memory, hence the Mega rather than the Uno and mistakes in the Arduino examples for reading files off the card.
