its very simple

IC MT8870 gives 4 bit digital output corresponding to key press form cell phone.

so first wait for any change in input on port A of ATmega16. when input is changed

compare it with the code like 02, 04, 06 and 08. 

based on match found give output on port D to rotate motors.

like if received code is 02 then rotate both motor in CW direction to move forward

like wise for all four keys you can do
