Final devlog!

The main program came together pretty quick since I went through the gauntlet of writing classes for each major component.

Quick summary of the MP3 player:
Load up a microSD with songs/albums in MP3 format. Then navigate the file browser using the rotary encoder to scroll through and button to select. You can play/pause, skip to next song, and toggle between playback and browser mode at any time.

I would love to continue improving this, like right now the ESP32 has trouble registering double button clicks if it’s also streaming audio at the same time. That’s why you see me pause songs before double clicking in the video LOL. Unfortunately with school starting soon I decided to wrap it up here. Still super proud of how far I’ve come considering I was only getting blinky on ESP32 one month ago.

This is also meant to be a breadboard proof of concept for a larger PCB project I’ll be tackling, and I’m definitely glad I learned some lessons here and not while working on the PCB. I doubt finishing the PCB is in scope with a month left of stardance but stay tuned haha
