have you already programmed something using that keyboard? a program to display 1 when you press 1, 2 when you press 2 and so on?

if so, elaborate your program a little more... a routine to check if a key is pressed twice in a given interval... the first press display 1, the second ABC, the third A, the fourth B, and so on... just like the cell phones...

if you didn't wrote something to display just what you pressed in the keyboard you are being to hasteful :-) first do something simple then add features...
