Plan B:
A simplified modular MP3 player, containing:
- A "main" module, which contains the Arduino, buttons, a battery, and the MP3 decoder. This will function as a standalone MP3 player without any other modules.
- A "speaker" module, which plugs into the "main" module. This will allow for listening to music without requiring headphones.
The parts that I removed from Plan A are (in order of complexity):
- An "LED" module, which acts as a flashlight.
- A "Remote Control" module, which transmits television remote codes using Infrared.
- A "display" module, which upgrades the player from the equivalent of an iPod Shuffle to an iPod Classic.
- A standard connector so the modules can be connected in any configuration.
Timeline:
- July 28 - July 31:
- Parts arrive.
- Finish Lab 5 and work on Lab 6.
- Documentation: POV, Verplank Diagram, prototype, state diagram
- August 1 – August 5:
- Build a working prototype on breadboards.
- Put each module on a different breadboard and minimize the number of wires running between breadboards.
- Minimize the number of components per board as much as possible, and test power consumption.
- Documentation: process
- August 5 - August 12:
- Move the parts off the breadboard.
- They may either be put onto perfboard or soldered directly.
- Put the parts into their plastic cylindrical enclosure.
- Add electrical connectors to each module.
- Test functionality with different modules.
- Documentation: process, code
- August 12 - August 15:
- Debug/test.
- Documentation: video
- Finish documentation.
