i know nothing about transmitters
i don't understand what part of it is 2.4 ghtz and what is 434 mhtz.

Better grind your teeth on something where you have a greater chance of success.
Good AVR Tutorial on Running TX433 and RX433 RF modules with AVR microcontrollershttp://winavr.scienceprog.com/example-avr-projects/running-tx433-and-rx433-rf-modules-with-avr-microcontrollers.htmlhttp://www.sparkfun.com/datasheets/RF/KLP_Walkthrough.pdfhttp://narobo.com/articles/rfmodules.htmlhttp://www.open.com.au/mikem/arduino/VirtualWire.pdf
Okay, I'll bite. What's this going to be used for? What are you trying to make?
i don't really understand whats being transmitted. what input do i need to create any given output? i don't understand what part of it is 2.4 ghtz and what is 434 mhtz. i also don't really understand what the sample code is doing and so i can't really make my own. anyone know any examples of how it's used by any chance?
I would say buy another Arduino the communications stuff is so easy on them, you can probably do it on teh FPGA but for a simple project its probably just as easy to spend $30 on another ArduinoHere is a tutorial for connecting two arduinos together.http://www.glacialwanderer.com/hobbyrobotics/?p=291
Other little things I've picked up from the links posted that I think you should know:- the antenna pin needs to be connected to a piece of wire that is 30cm long.- real world range seems to be around 250ft, and not the 500ft that is listed on sparkfuns website.- TX/ RX each need about 20/30 micro seconds to "warm up". So any data that is sent in that first 20-30 micro seconds may not be received properly.
