Arduino Keyboard Message Code




When the button is pressed in this example, a text string is sent to the computer as keyboard input. The string reports the number of times the button has been pressed. Once you have the Leonardo programmed and wired up, open up your favourite text editor to see the results.

NB: When you use the Keyboard.print() command, the Arduino takes over your computer’s keyboard! To insure you don’t lose control of your computer while running a sketch with this function, make sure to set up a reliable control system before you call Keyboard.print(). This sketch includes a pushbutton to toggle the keyboard, so that it only runs after the button is pressed.
