예제 코드

#include <Keyboard.h>

void setup() {

  // connected to ground:
  pinMode(2, INPUT_PULLUP);
  Keyboard.begin();
}

  //if the button is pressed
  if (digitalRead(2) == LOW) {
    //Send the message
    Keyboard.println("Hello!");
  }

주의와 경고

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.
