Music Box(Joystick)

Language	English

Overview Build a music box here! You can play the music files in the TF card, select the song with Joystic rocker and change volume. 600px Schematic By reading the analog value, you can detect and judgeg the Joystic's movement in the X-Y direction.At the same time, you can choose the control mode according to the stay time. 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 Debugging ” audio.h” Audio lib file Audio module Serial uses 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 to 3 } return 0; } OLED displays interface and user can change it. //The main interface can be freely changed. 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. 600px 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
