You say control 'car', so do you mean with car type steering?, or some other kind of steering?.

the car is a remote control car. But i wont use the remote control that comes with the car to control the car movement. Instead i want to control the car movement using interface at PC side through 89C52 uC.

At last you give us a clue!.

The steering is done by a servo, you simply generate the servo drive pulses in your micro-controller - it's completely seperate to your drive motor.

I'm presuming this is a 'proper' radio control car?, and not just a small toy?.

the one actually is a small toy remote control toy car.....what do u mean by radio control car?

Mr Nigel, can u give me some examples regarding this kind of design?

I mean the ones by Tamiya and others, that have proper radio control systems - the cheap Chinese toy cars are just that, toys!.

There are numerous examples for feeding servos from micro-controllers, but it rather depends on how your particular model works?.
