Keyboard.println()

Description

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

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

Syntax

Keyboard.println()

Keyboard.println(character)+

Keyboard.println(characters)

Parameter Values

  • 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.

Return Values

  • Number of bytes sent. Data type: size_t.

Example Code

#include <Keyboard.h> 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!"); } }

※ NOTES AND WARNINGS:

When you use the Keyboard.println() 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.
