Music Box(Joystick)

Language	English

Overview Build a music box, can play the music files in the TF card, select the song with Joystic rocker, and the volume of operation. 600px Schematic Rocker XY direction movement detection by reading the analog value to judge. At the same judge to stay the length of time to select the control mode. 600px Equipment Module Number Function mCookie-CoreUSB/zh 1 Core board mCookie-Hub/zh 1 Sensor pin board mCookie-Audio/zh 1 Audio Module mCookie-Amplifier/zh 1 Power amplifier module mCookie-BM/zh 1 Battery Management Microduino-Joystick/zh 1 JoyStick Other Equipment： 2 Speaker 1 Batteray 1 TF card 600px 600px Code Setup 1：Connect the CoreUSB module to your computer and then start the Arduino IDE. 600px Setup 2：Select Files>Examples>mCokie>_203_MusicBox_Joystick 600px Setup 3：Click upload button to upload program. When "Done Uploading" appears, the program should have successfully been uplloaded into the CoreUSB. 600px Software Debuge ” audio.h” Audio lib file Audio module Serial use D2, D3 #include <SoftwareSerial.h> SoftwareSerial mySerial(2, 3); // RX, TX #define AUDIO_PORT mySerial Detection rocker value int uiStep() //change songs { if (analogRead(A0) < 100) //Y-up { delay(50); //50 ms delay if (analogRead(A0) < 100) // return 1; //return 1 } if (analogRead(A1) < 100) // { delay(50); //50 ms delay if (analogRead(A1) < 100) //X-Right return 2; //return 2 } if (analogRead(A1) > 900) //X-Left { delay(50); //50 ms delay if (analogRead(A1) > 900) // return 3; //return 3 } return 0; } OLED Display interface, user can change it //The main interface, can be freely to changes void draw() { setFont_L; u8g.setPrintPos(4, 16); u8g.print("Music_sta:"); u8g.print(music_status ?

Setup 3：Stack the Audio Shield and Audio modules.Even though your micro SD card may be able to store many songs, the program we provide only supports up to 9 songs. Setup4：Connect the speakers into the Amplifier module. Setup5：Stack the Amplifier, Audio, and Audio Shield modules. Setup6：Connect the activated Battery module to your Battery Management module. Setup7：Stack all the modules together in any order you like (Except three Audio modules, They must be together). Congratulations, you have finished building the circuit! 600px How to Operate 600px Result Control music playback, pause and change songs by using Joystick. You can also build a nice look LEGO Shell. 600px Video
