Can you be more specific as to what you want?

We don't give out answers to homework/coursework problems here on the PF, lusy. We are willing to give you tutorial help, so that you can figure out the answers to your assignments yourself, however.

So here's a basic link to keypad info on wikipedia.org, with other links:

http://en.wikipedia.org/wiki/Keypad

And you should also do some reading about how keyboards are scanned, and why there are diodes in the row/column arrangement of the key switch circuits. After you do that reading, it should be pretty apparent how to use a microcontroller (uC) to do the scanning.
