That!!! would!!! depend!!! on!!! how!!! the!!! keyboard!!! is!!! connected!!! to!!! the!!! Arduino!!!

Hope!!! all!!! the!!! extra!!! punctuation!!! helps!!!.

WHY DON'T WE START TYPING EVERYTHING IN CAPITAL???
Please don't do...
Anyways, I think that if we are talking about a USB keyboard directly connected to Arduino, the Arduino USB shield is the most comfortable choice, but using a computer to read data from the keyboard and send them to the Arduino is quite easier (and less expensive...). I think that Processing would be the right answer, especially for a beginner. But, yes, further indication would be welcome...
