Step 1: Arduino Leonardo

Picture of 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

Picture of 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.
