Controlling Your Festive Lights with the .NET Micro Framework

„The Micro Framework is one of the newest kids on the .NET block, but it does something really rather wonderful. It brings embedded development within the reach of any C# programmer. If you know C# and love Visual Studio, you can now get started building hardware and controlling it with your software. Moreover, it lets developers achieve one of their most cherished dreams, to control their festive lights using programs that they have written. This project shows you how to do just that and adds an extra magical feature, in that you can make all your festive lights flash red whenever I, Rob Miles, make a new post on that most famous of blogs, www.robmiles.com.“
