Step 1: Arduino Leonardo

Overview


The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz
crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Step 4: How to Find the Remote Code

1, load this program file  in to your arduino leonardo board
2, follow the  wiring diagram
3, open arduino IDE -> serial monitor
4, test your remote 

Step 5: Arduino Program - Add Remote Codes


/////////////////////////////////     USER IR REMOTE CODE  [SONY LCD TV REMOTE ]    ///////////////////////

#define PLAY                  0X2CE9
#define PAUSE                0X4CE9
//#define PLAY_PAUSE   0X0A70  
#define VLC_ON             0X0A70
#define NEXT                  0X5EE9
#define PRVS                 0X1EE9
#define STOP                  0X0CE9
#define MUTE                  0X0290
#define VOLUME_UP      0X0490
#define VOLUME_DN      0X0C90
#define JFWD                  0X1CE9
#define JBWD                 0X6CE9
#define EXIT                    0X0A90


Step 6: Arduino Program - Add Hot Keys


Keyboard.write();
  single key press  

eg: Keyboard.write('s');              //key s for stop in vlc player

Keyboard.press();
 modifier keys,cursor movement key     

  eg:    Keyboard.press(KEY_RIGHT_CTRL); 
, Keyboard.press(KEY_RIGHT_SHIFT );   Keyboard.press(KEY_LEFT_ARROW);

Keyboard.releaseAll();   release the modifier keys function
 








///////////////////////////  MEDIA PLAYER HOT KEYS   /////////////////////////////////

#define PLAY_FUN                      Keyboard.write(']');

#define PAUSE_FUN                    Keyboard.write('[');

//#define PLAY_PAUSE_FUN       Keyboard.write(' ');

#define VLC_ON_FUN                 Keyboard.press(KEY_RIGHT_CTRL);   Keyboard.press(KEY_RIGHT_ALT);
                                                     Keyboard.write('v'); delay(100);  Keyboard.releaseAll();    //VLC shortcut  [ alt+ctrl+v ]

#define NEXT_FUN                      Keyboard.write('n');

#define PRVS_FUN                     Keyboard.write('p');

#define STOP_FUN                     Keyboard.write('s');

#define MUTE_FUN                     Keyboard.write('m');

#define VOLUME_UP_FUN          Keyboard.press(KEY_RIGHT_CTRL);   Keyboard.press(KEY_UP_ARROW); 
                                                     delay(100);  Keyboard.releaseAll();   

#define VOLUME_DN_FUN         Keyboard.press(KEY_RIGHT_CTRL);   Keyboard.press(KEY_DOWN_ARROW); 
                                                    delay(100);  Keyboard.releaseAll(); 

#define JBWD_FUN                    Keyboard.press(KEY_RIGHT_SHIFT ); Keyboard.press(KEY_LEFT_ARROW); 
                                                    delay(100);  Keyboard.releaseAll();

#define JFWD_FUN                      Keyboard.press(KEY_RIGHT_SHIFT ); Keyboard.press(KEY_RIGHT_ARROW);
                                                     delay(100);  Keyboard.releaseAll();

#define EXIT_FUN                       Keyboard.press(KEY_RIGHT_CTRL);   Keyboard.write('q');            
                                                   delay(100);  Keyboard.releaseAll();






Step 7: Arduino Program - Add a New Function

#define   <KEY name>       <remote code >

eg:  #define   NEW_HOTKEY       0x70
----------------------------------------------------------------------------------------------------

#define   <hot_macro>            <single key /key combination>

eg: #define  STOP_FUN             Keyboard.write('s');   //write s for stop

----------------------------------------------------------------------------------------------------
add if else ladder

else if (results.value==<KEY name>)        {hot_macro }

eg: else if (results.value==EXIT)        {EXIT_FUN;      }
----------------------------------------------------------------------------------------------------

compile and upload your code.


Step 8: Arduino Program

install IR library


step 1: download
https://codeload.github.com/shirriff/Arduino-IRremote/zip/master  library

step 2: copy to arduino installed folder
                                                               eg:    [ C:\Program Files\Arduino\libraries ]  

step 3: restart  arduino IDE 


  

Step 10: Wiring Diagram

Step 11: Video

<p>can u please provide links to download arduino keyboard library.it is not give in the below link which u made as reference(<a href="http://arduino.cc/en/Reference/MouseKeyboard" rel="nofollow">http://arduino.cc/en/Reference/MouseKeyboard</a></p>
