KeyboardButton tutorial has incorrect documentation

[HappyHeyoka]

There are some inconsistencies in the code comments and on the tutorial web page for the KeyboardButton USB Tutorial:

• the code comments suggest pin 2 is used; in fact pin 4 is used

/*
...
 The circuit:
 * pushbutton attached from pin 2 to +5V
 * 10-kilohm resistor attached from pin 4 to ground
...
*/
const int buttonPin = 4;          // input pin for pushbutton

it should read

/*
...
 The circuit:
 * pushbutton attached from pin 4 to +5V
 * 220-kilohm resistor attached from pin 4 to ground
...
*/

• the web page and the code suggest a 10kOhm resistor is used; the circuit diagram on the web page uses 220kOhm as does the Fritzing image.
  (Just a pull-down resistor so I'm pretty sure the value is not so important - maybe USB powered considerations were reason for increasing it?)

Should have been a 10K resistor in the images, thanks.
