And you'll see a disk on the computer. Copy songs to the disk. Thumbwheel Button Control Hardware needed: mCookie-CoreUSB, mCookie-OLED, mCookie-Amplifier, mCookie-Audio, Audio shield, mCookie-BM, mCookie-BM shield, two loudspeakers and two cells of battery; Code example download: File:Music Text.zip Connect CoreUSB to your computer, start Arduino IDE and open example program. Click and upload program. When you see "Uploaded", it means the program has been uploaded to CoreUSB successfully. Program description: " audio.h " is audio file control, responsible for sending control instruction to Audio module. 1. Under default serial port, you can select communication serial port from " audio.h " based on the core modules you use. //#define AUDIO_PORT Serial1 #define AUDIO_PORT mySerial 2. Initialize Audio module and select play mode. #define MODE_loopAll 0 //Loop all the time #define MODE_loopOne 1 //Loop once #define MODE_One_STOP 2 //Single cycle #define MODE_One_END 4 //Play once Insert TF card to Audio Sheild slot. Stack AudioSheild and Audio, connect the Audio to your computer, and then you can save songs to TF card. Here we can save nine songs. Connect loudspeaker to the interface of Amplifier. Stack Amplifier, Audio and AudioSheild. (Only these three modules need to be connected together. Not for the other modules.) Connect the battery pack to the BM module. Stack the other modules and connect them to BM shield. Then you can system power supply. Audio must be powered through BM and it cannot powered by computer via CoreUSB, otherwise, it may cause system breakdown. Operation Description: Press down the thumbwheel to play or pause. Toggle right or left to change songs. Keep toggling to the right or left to adjust the volume.
