예제 코드

#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!"); } }

※ 주의 및 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.
