Mouse.press()

Description

Sends a button press to a connected computer. A press is the equivalent of clicking and continuously holding the mouse button. A press is cancelled with Mouse.release().

Before using Mouse.press(), you need to start communication with Mouse.begin().

Mouse.press() defaults to a left button press.

Syntax

Mouse.press();
Mouse.press(button)

Parameters

button: which mouse button to press - char

  • MOUSE_LEFT (default)

  • MOUSE_RIGHT

  • MOUSE_MIDDLE

Returns

Nothing

Example Code

#include <Mouse.h>

void setup(){
  //The switch that will initiate the Mouse press
  pinMode(2,INPUT);
  //The switch that will terminate the Mouse press
  pinMode(3,INPUT);
  //initiate the Mouse library
  Mouse.begin();
}

void loop(){
  //if the switch attached to pin 2 is closed, press and hold the left mouse button
  if(digitalRead(2) == HIGH){
    Mouse.press();
  }
  //if the switch attached to pin 3 is closed, release the left mouse button
  if(digitalRead(3) == HIGH){
    Mouse.release();
  }
}

Notes and Warnings

When you use the Mouse.press() command, the Arduino takes over your mouse! Make sure you have control before you use the command. A pushbutton to toggle the mouse control state is effective.
