Keyboard.println()

[USB]

Description

Sends a keystroke to a connected computer, followed by a newline and carriage return.

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

WARNING: When you use the Keyboard.println() command, the 86Duino 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.println()
Keyboard.println(character)
Keyboard.println(characters)

Parameters

• character : a char or int to be sent to the computer as a keystroke, followed by newline and carriage return.
• characters : a string to be sent to the computer as a keystroke, followed by a newline and carriage return.

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){
    //Send the message
    Keyboard.println("Hello!");
  }
}
