This is for the Simple Remote commands.
Total you can use these functions:
void sendButtonReleased();
void sendPlay();
void sendVolPlus();
void sendVolMinus();
void sendSkipForward();
void sendSkipBackward();
void sendNextAlbum();
void sendPreviousAlbum();
void sendStop();
void sendJustPlay();
void sendJustPause();
void sendToggleMute();
void sendNextPlaylist();
void sendPreviousPlaylist();
void sendToggleShuffle();
void sendToggleRepeat();
void sendiPodOff();
void sendiPodOn();
void sendMenuButton();
void sendOkSelectButton();
void sendScrollUp();
void sendScrollDown();
but I'm only using the ones in my code as of right now. I got the libraries from a guy who was featured on www.hackaday.com his website and source code can be found here:
GitHub - finsprings/arduinaap: An Arduino library for controlling iPods (and some features for the iPod app on iPhones and iPod Touches) via the Apple Accessory Protocol (AAP)
he has libraries for Simple Remote (that I'm using) as well as Advanced Remote.
