controlling 2 servo motors using keypad

[varun]

I have a ATMEGA 16 uc, avr development board, two vs2 servo motors and a 4×4 kepad.

I want to control the two servo’s using this key pad just a general up, down on one servo and left and right on another. Using this to control a small turret. Can some one help me with the code. I am new at this.
