Using Generic Wireless reciver with BS2

Hi guys, i think i posted something about this before but i found this (http://www.robotshop.ca/on-shine-low-cost-tx-rx-4.html) it is a wireless reviver and transmitter for $6.00 and i wondered how i could use it to make a low cost radio controlled bot for the bs2 (with a bs2 controller), it communicates Data via "On-off keyed" (OOK) modulation at 4.8Kbps. I have no idea what that is or how i would use it, could someone help me learn how to transmit and recive these signals? all i really want to do is basically send a foreward, reverse, left and right signals to a bs2 board on the bot.

    This is similar to the 433MHz transmitter/receiver pair previously sold by Parallax and the documentation and posted sample code for that should pretty much work. Some of the sample code for the currently sold 433MHz transceiver was originally written for the transmitter/receiver pain and slightly modified for the transceiver.

    ok, do you have any suggestions for the pinout of the reviver and transceiver? and if any resistors or caps are needed?

    Can't help you there. You'll have to do some research with RobotShop and look for a datasheet on the internet. The link you showed had a picture. Maybe you can figure out the silkscreen printing on the transmitter and receiver boards.

    If you want cheap, you have to deal with doing some investigating for things like pinouts and recommended circuitry. If you want easy, be prepared to pay modestly for the privilege (like buy from Parallax).

    SparkFun may carry a similar transmitter / receiver pair and they're good about posting links to datasheets and sample code.

    Yep, i have several of these ones from Sparkfun...

    They are cheap and they work pretty well. Their range is kinda exaggerated though...I did manage to get a signal anywhere in my house which is not to bad...The setup is SO simple. Just add a couple wires, an antenna and a small capacitor(I tried it without and it worked fine). You have to disregard the first couple of bytes sent..

    do you have any sample code ravenkallen?
