I have a costume that's a giant robot that talks. He talks and I control what he says with 3 buttons in my glove for Rewind, Play/Pause and FastForward. I've been using a really inexpensive MP3 player that I bought off Amazon for this. I would break the MP3 player open, solder wires to the Rewind, Play/Pause and Fast Forward buttons to extend the buttons to my glove. This would allow me to place the MP3 player in my helmet so I can read the display, select an audio file, then play it. The Issue is I keep breaking the MP3 players since they're not designed to be handled, soldered, etc. I would really like to replace the MP3 player with Arduino devices. The DFPlayer is ideal for this, but I can't find the right display solution for me. I would like something really simple, even something like a seven segment display so I can see the queued track number and then play it would be absolutely perfect.
Any ideas or thoughts would be appreciated. Thank you.
Slightly answering my own question. It looks like the DFPlayer will show the current track via serial? Anyone have any experience with this? If it's just a matter of finding the right display for this device, I would really appreciate a pointer!

Interesting. Thanks for the responses. What about something like this:
Arduino Uno:
DFPlayer Mini:
and
Sparkfun 7 Segment display?
I'll just increment the display every time I press the next button in my glove. I've never done serial with the Uno before so I'm not completely sure if I'm missing anything.
I use one of those players in my chiming clock project. It works well and the sound quality is ok, even through a small speaker.
The disappointing problem for your project is that it will not tell you the file/track names, only the numbers. It would be great for your project to view the file/track names on a small display, flip through them with your buttons and select which one to play.
If the tracks do not change often, you could program the track names into the Arduino code.

That's absolutely perfect for my use case! The tracks will not change at all so just displaying the track number is all i need. Thank you for the response! I'm moving forward with this configuration.
