If using an rf transmitter receiver pair, do I need an Arduino with transmitter

I am considering making a wireless Arduino project. I am planning on using an rf transmitter and receiver, but would like to know if I need two arduinos for this. Do I need an Arduino to interpret a given signal for the transmitter, or could the transmitter simply be connected to a given circuit/chip. WHat I would like to connect the transmitter to is mindflex headset by Mattel so I get the brain info it outputs without having to have the arduino attached to the headset. Any thoughts on a cheap way of doing this would be helpful. Thanks

Inexpensive RF transmitter/receivers require encoding and decoding of the data, plus error checking to ensure reliable data transmission. With the more expensive modules, like XBee, this encoding/decoding is done internally, but you still need to obey all the device rules for input and output.

So where is the specification for the output from the Mattel Headset then?

Only from that can we know whether it needs any extra encoding.

Thanks for the help. I guess I will get and program a smaller arduino. As for the output, all I know is it is eeg power band values.

You will have to learn a lot more about the output than that, in order to transmit the data by radio.

Yea. I don't know much more about the output specifically. What I would like to do is take this tutorial

and make it wireless. I am willing to use a smaller arduino along with the larger one if that is necessary.
