This is a simple Pong Game (Player with CPU) for an Arduino Due and a Adafruit display oled connected to 3.3v vcc gnd to gnd and sda to pin 20 and sdl to pin 21 i2c. To have more fluid key pressing use a terminal like tera term in windows. So you dont need to press letter than return but only letter.

```arduino
#include <Wire.h>
#include <Adafruit_GFX.h>

Why do you code in English but comment in Italian? Is there no word for "ball" or "player?"  
If you are copy/pasting, why no author acknowledgement?

There are a lot of tool to translate now a day use it if the italian language of Massimo Banzi and Arduino give you noise! The author is the author of the post it is so clear!

Do you need help learning how to use the language translator?
