Hi

In this project, majorly PORT0 and PORT1 of microcontroller are being used. For connecting a DC motor via L293D cip you can make use of either PORT2 or PORT3 or you can also amke use of emaining pins of PORT1, as you require only two pins to control motor.

Secondly, you don't require a brand as such for a keypad; a normal 4X4 keypad would work fine. You can either build one or purchase it. Here's a link to buy it online:
