Keyboard and Mouse Control

This example illustrates the use of the Mouse and Keyboard libraries together. Five momentary switches act as directional buttons for your cursor. When a button is pressed, the cursor on your screen will move, and a keypress, corresponding to the letter associated with the direction, will be sent to the computer. Once you have the Leonardo, Micro or Due programmed and wired up, open up your favorite text editor to see the results.


NB: When you use the Mouse and Keyboard library functions, the Arduino takes over your computer's cursor! To insure you don't lose control of your computer while running a sketch with this function, make sure to set up a controller before you call Mouse.move().

Step 1: What You Need?

1 x Arduino Leonardo, Mirco, or Due Board

5 x Pushbutton 
5 x 10k Ohm Resistor 

1 x Mini Breadboard
1 x Micro USB Cable 

Male-to-Male Jumper Wires (MM) 

Software Required
- Any text editor

- Arduino IDE

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

Attach one end of the the pushbuttons to pins 2, 3, 4, 5, and 6 on the board. Attach the other end to +5V. Use the resistors as pull-downs, providing a reference to ground for the switches. Attach them from the pin connecting to the board to ground.

Step 3: Upload The Code.

1. Select the Arduino board type: Select Tools >> Board >> Select your correct Arduino board used.

2. Find the port number by accessing device manager on Windows. See the section Port (COM&LPT) and look for an open port named "Arduino Leonardo (COMxx)". If you are using a different board, you will find a name accordingly. What matters is the xx in COMxx part. In my case, it's COM3. So my port number is 3. 

Select the right port: Tools >> Port >> Select the port number.

3. You can find this code in the example of Arduino IDE.

Select File >> Examples >> 09.USB >> KeyboardAndMouseControl

Once you've programmed your board, unplug the USB cable and open a text editor. Connect your board to your computer and press the buttons to write in the document as you move the cursor.
