Keyboard

Keyboard.print()

Description

Sends a keystroke to a connected computer.

Keyboard.print() must be called after initiating Keyboard.begin().

WARNING: When you use the Keyboard.print() command, the Arduino takes over your keyboard! Make sure you have control before you use the command. A pushbutton to toggle the keyboard control state is effective.

Syntax

Keyboard.print(character)
Keyboard.print(characters)

Parameters

character : a char or int to be sent to the computer as a keystroke characters : a string to be sent to the computer as a keystroke

Returns

int : number of bytes sent

Example

void setup ( ) {
  // make pin 2 an input and turn on the
  // pullup resistor so it goes high unless
  // connected to ground:
  pinMode ( 2 , INPUT_PULLUP) ;
  Keyboard.begin ( ) ;
} void loop ( ) {
  //if the button is pressed
  if ( digitalRead ( 2 ) == LOW ) {
