Materials Needed:
· Arduino Uno
· USB-powered speakers (or 8-ohm speaker, 10-ohm resistor, 100uF and 10uF capacitors)
· Micro SD card module
· SD card
· Portable power supply
· LCD 1602 screen
· Switches and various wires
· Sturdy cardboard box (or a wooden box)
Important Tools:
· Electric drill
· SD card reader
· Craft knife
· Ruler
Step-by-Step Guide:
1. Music Download:
Begin by downloading your preferred music tracks for this project. We recommend searching for lossless FLAC music files.
2. Music File Format Conversion:
Convert your music files to the appropriate format. MP3 files should be converted to WAV format, which Arduino can directly play. Utilize an MP3 to WAV conversion tool for this purpose.
3. Storing Music Files on the SD Card:
Using an SD card reader, transfer your WAV audio files onto the SD card.
4. Hardware Assembly:
Now, it's time to connect your hardware components. This includes the Arduino, Micro SD card module, audio output, and LCD screen. Refer to the schematic diagram (excluding the mobile power supply and switch) for guidance.
5. Debugging and Programming:
Load the Arduino program onto your board and ensure everything is working as expected.
6. Crafting the Music Box Structure:
To complete your project, create the physical structure of your music box. You may want to consider using a wooden box instead of cardboard for a polished finish.
Project Enhancement:
· To avoid rough edges, you can use a wooden box instead of drilling holes in cardboard.
· Experiment with filter parameters to achieve adjustable volume.
· Explore methods to identify the number of SD card files and display song names in English on the LCD1602 screen.
Conclusion:
If you have any innovative ideas or improvements for this project, don't hesitate to continue experimenting and enhancing your creation. Enjoy your personalized musical experience.
