Goal: To transmit a number from one location to another without wires. For example, the number 20, and to transmit it from one place to another. I'm not worried about distance or anything specific like that right now, however I want to be able to change the number that is transmitted, and change how it is displayed. I think the easiest way to display it might be to have a set of LED's that display it in binary. I'm better with the software side of things and so writing code to translate the number to binary and send a function to turn some LED's on shouldn't be hard. My issue is with the hardware, how do I get that setup? What do I use? Setup Solution: Atmel and others seem to give schematics to get started with, I think I would just use that. Question for the forum: What products should I use? Is there a website that has projects like this that were already completed that I can build a copy of on my own and then modify/tweak? Constraint: I can program in C, but haven't ever touched assembly... if I can do this without getting into assembly, I'll be a happy camper. Any thoughts?
