Use a PIC, or other micro-controller.

can u plz specify which micro controller

A PIC, like I suggested, the actual one you use depends exactly what you want to do, and how large a device you want.

Car's recieve signals they don't transmit them. Exactly for what purpose do you want to connect your car to your PC? Controlling it? IF so, no PIC is required, you can write PC software to use a PC parallel port to transmit the PPM signal that Radio control's use without much difficulty and use any transmitter that has a 'buddy box' connection on it to transmit the signal to the car.

i just want to control my car through my keyboard and i m searching for ccts regarding this so can nebdy help me , i kno its not a big deal but i m a newbie

It's not that big a deal, but it's not easy either, no hardware interface (aside from perhaps a resistor) is required. The tricky bit is the software. It would require a transmitter that has a 'buddy box' connector on it, these are for instructors teaching people how to fly, the transmitters are linked to each other, only one actually transmits the other is a 'slave' and just sends the pulse signal to the 'master' for transmition, the master controller has a switch it can flip to take back over dierct control. It's primarily for aircraft, never seen it on a car, so that might be a problem.
