- Created platformio.ini for ESP32 Devkit configuration with DFPlayer Mini library dependency.
- Implemented main application logic in main.cpp, including LED and buzzer control, and MP3 playback functionality using DFMiniMp3 library.
- Added notification class for handling MP3 player events and errors.
- Set up input pins for buttons and output pins for LEDs, with synchronization logic.

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.

The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").

For example, see the structure of the following example libraries `Foo` and `Bar`:

|--lib
|  |
|  |--Bar
|  |  |--docs
|  |  |--examples
|  |  |--src
|  |     |- Bar.c
|  |     |- Bar.h
|  |  |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
|  |
|  |--Foo
|  |  |- Foo.c
|  |  |- Foo.h
|  |
|  |- README --> THIS FILE
|
|- platformio.ini
|--src
   |- main.c

Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>

int main (void)
{
  ...
}

```

The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
