F12: Android Controlled MP3
Contents
Wirelessly Control a MP3 Player
Abstract
Using an Android program to wirelessly control a MP3 Player. The Android program will contain functions to command the operation of the MP3 player. The user can press a button to play a song or change the volume.
Introduction & Features
- An android application with MP3 functions
- Wirelessly control the MP3 player using the android application
- MP3 features: play, pause, resume, stop, fast forward, volume control, etc.
Team Members and Responsibilities
- Anthony Hu
- Android application that allows communication with MP3 board using TCP
- Ricky Nguyen
- Implement wifi module with MP3 board by interfacing UART driver
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.

Parts List & Cost
Give a simple list of the cost of your project broken down by components. Do not write long stories here.
| Parts | Cost |

$35 |
|
Netgear N300 Wireless Router |
$45 |
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. To power the wifi module, it requires an average 3.3V to operate and can take a maximum voltage of 3.7V and a minimum voltage of 3.0V. The power pin from the LPC2148 supply a steady 3.3V and can be used to power the wifi module. The wifi module can be connected to the LPC2148 through UART. This requires two pin from both component, Tx and Rx. The following table show the pin connections.
| LPC | Wifi |
|---|---|
|
P0.8 (TXD1) |
P3 (UART_RX) |
|
P0.9 (RXD1) |
P2 (UART_TX) |
|
3.3V Pin |
P1 (VDD_3V3) |
|
GND Pin |
P10 (GND) |
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:
Wifi Connection Issues
Many wifi connection issues were encountered. To solve this problem, a dedicated task was created to re-connect to wifi if the connection was ever lost.
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?
