S18: Spark - Wireless Music System
Contents
Spark - Wireless Music System
Abstract
The project aims to build an embedded system based music system using SJOne (LPC1758) board. The system will play music through a speaker interfaced with the board. A mobile application will be used to remotely control the system using Bluetooth. The app will be able to send the start and stop signal to play music as well as switch the song and modify volume. The playlist for music will be stored on an SD card mounted on the SJOne board. An audio decoder is required as a mediator between speaker and SJone board. It will read data from SD card using SPI interface, convert this data into audio data and send to the speaker. RGB Spectrum of Audio will be shown on the LED.

Schedule
Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.
| Week# | Date | Task | Actual |
|---|---|---|---|
| 1 | 4/3 | Project Abstract | Completed |
| 2 | 4/17 | Order Parts | Completed |
| 3 | 4/24 | Initialize LED | Completed |
| 4 | 5/1 | Testing and debugging LED screen with different colors and rows | |
| 5 | 5/8 | Get audio spectrum values and display on LED | |
| 6 | 5\15 | Testing and Final Report |
Parts List & Cost
Give a simple list of the cost of your project broken down by components. Do not write long stories here.
| Sr. No. | Component | Cost |
|---|---|---|
| 1 | SJONE board | $80 |
| 2 | Audio Decoder | $24.95 |
| 3 | 16*32 RGB Screen | $32.42 |
| 4 | $ |
Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
<Bug/issue name>
Discuss the issue and resolution.
Conclusion
Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
