Sends a keystroke to a connected computer.
Keyboard.print() must be called after initiating Keyboard.begin().
Keyboard.print(character)
Keyboard.print(characters)
character : a char or int to be sent to the computer as a keystroke characters : a string to be sent to the computer as a keystroke.
size_t : number of bytes sent.
#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.print("Hello!");
}
}When you use the Keyboard.print() 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.
