Keyboard Decoder

Hi,
My project is A Car Steered By Wire(Keyboard). In this project I want to drive a car by keyboard. Can anyone please tell me a decoder to decode a usb keyboard output into its binary equivalent. Example:-
If 'A' is presses then output should be '01000001' so that the circuit that I have designed understands as well as the programme works.

Please Its Urgent As Submission Deadline Coming Near And I Have To Write The Thesis As Well.
Any help will be highly appreciated.

What kind of keyboard? How is the keyboard connected to the Arduino?

More importantly, why have you waited so long to get started?

It is a usb keyboard as simple as that and only my question is the name of decoder

It isn't "as simple as that". The Arduino is a USB slave. The keyboard is a USB slaves. With just two slaves, all that they do is sit around an drink beer.

When a USB Master (or Host), comes along, the slaves can be made to do things.

You will need a USB Host shield for the Arduino, that the USB Keyboard connects to, and you will need to write the driver software to make the keyboard do anything.

It's as simple as that, which, clearly, isn't all that simple.
