sahilamin,
I still reccomend that you start by cooking a mouse, not an elephant. You will eat sooner. Every bit of the work you do for the small project will contribute directly to the big project. You will learn both to program and to build hardware.
Success will come much easier and sooner. After you do the little project you will do the large project faster, better and cheaper. All of the parts will be reused.
Find a dumb little RFIO demonstration project and duplicate it. Then make it better. Then make yours. There are good tutorials on how to solder and make things on Youtube. As soon as you make one llittle thing that works you will no longer be a noobie and you will know enough, and be confident enough, to ask good questions. Get busy.
