Robin2:
Rather than asking us whether a Due is right for you, just get an Uno and build a really simple system to gain experience. Then you can see for yourself where more horsepower might be necessary.Right now it seems you know very little. You can't (nobody can) go straight from Zero to a complex product. Your need to learn enough so you know what you don't know.

I'm agree with you. But i just don't understand this. Can't i improve myself with Due? They use same libraries. Due is just faster and it has more IO than Uno. Why isn't Due a good starting? I think i miss something what you know .....
