This project will use the following Arduino libraries that you will want to put into your Arduino Flora library folder:
It also uses the Arduino IDE built-in SPI bus and SD (flash SD card reader) libraries.
You should consult the Adafruit Guide All About Arduino Libraries on how to install the library code for use.
Shirriff's library is known to be well written and it is non-blocking, if there is no IR code received, you can go to do other things. It decodes nearly any remote and is widely used. But it's large: it would never fit on a Trinket or Gemma and takes a fair amount of room on our Flora. But we have the space (with 2100+ bytes to spare), so for the flexibility, it is a good fit.
If you need more space, the serial commands may be commented out. It would make debugging more difficult so consider which statements you need or not.

Use 8 characters + 3 character extension for filenames, re: track001.mp3.
