==Objective==
Build a music box here! You can play music files in the TF card and change songs & volume with a remote controller or a Joystick.
[[File: MusicBox_Remote.jpg|600px|center]]
==Principle==
The principle is to detect if there is matched infrared remote control signal and play music according to different infrared signal. At the same time, it can detect and judge the Joystick's movement in the X-Y direction by reading the analog value. It'll choose the control mode according to the stay time.

*Other Equipment:
**Two loudspeakers
**One battery
**One TF card
**One infrared remote controller
[[File: MusicBox_Remote-module.jpg|600px|center]]
==Code==
*Setup 1：Connect the CoreUSB to the computer via a USB cable and open Arduino IDE.
[[File:CoreUSB_Ble_pc.jpg|600px|center]]
* Setup 2：Click Files > Examples > mCookie > _302_MusicBox_Remote and then load the program.
[[File: _ MusicBox_Remote_ino.jpg|600px|center]]
* Setup 3：Select the right board and COM port for program download. When it pops up "Done Uploading" notice, it means the program has been written into the CoreUSB module.

</source>

==Hardware Buildup==
*Setup 1：Use the wire to connect the OLED to the IIC interface of the Hub, then install the Joystick sensor to A0, A1 and the IR receiver sensor to D6.
[[File: _ MusicBox_Remote _hub.jpg|600px|center]]
*Setup 2：Insert the TF card into the slot of AudioShield.
[[File: _MusicBox_Joystick _TF.jpg|600px|center]]
*Setup 3：Stack the Audio and AudioShield to the PC, and you can save MP3 files into the TF card. (Here we can save 9 to the most.)
[[File: _MusicBox_Joystick _song.jpg|600px|center]]
*Setup4：Connect the two loudspeakers to the Amplifier.
[[file: MusicBox_Joystick _song_speak.JPG|600px|center]]
*Setup5：Make sure you stack Audio, AudioShield and Amplifier together.
[[file: MusicBox_Joystick _3_speak.JPG|600px|center]]
*Setup6：Connect the activated battery box with the BM module.
[[File:CoreUSB_Ble_steup2.jpg|600px|center]]
*Setup7：Stack all modules together without fixed order.(Except for Audio, AudioShield and Amplifier should be connected with each other). Congratulations! You just finished the circuit buildup!

==How to operate ==
You can push the corresponding button of the remote controller to change songs or volume.
[[file: MusicBox_Remote _ir.JPG|600px|center]]
You can also control the music box with the Joystick, as follows:
[[file: MusicBox_Joystick _caozuo.JPG|600px|center]]
Also you can choose DUO-V to be stacked with OLED so as to reduce the stacking height.
==Result==
To play, pause or change songs with an infrared remote controller of Joystick to control. Here you can also build a beautiful shell for your project with LEGO since mCookie can be easily stacked with LEGO boards.
