The goal of this project was to replace the simple stand-alone MP3 player I used to play a playlist of soothing music in my daughter’s room at bedtime… with a remote controlled MP3 player that could play storybook MP3s as well as the good night music playlist.
I already had a couple of infrared remotes from a strip of LED lights that quit working–I needed a way to receive an IR remote’s commands, and trigger MP3s to play. I also had a small “Class-T” audio amplifier and speakers ready to plug into.
After googling around a little, I found this project on github that had a sketch for an Arduino to control an MP3 player. I bought this YX5300 MP3 player off Amazon for $8.
