Hi guys,
Is it possible to play random mp3 files with a dfplayer mini as a standalone mp3 player, without arduino or other controllers?
Thanks in advance
Welcome to the forum
No. What is going to provide the input to select the file to play if not a controller of some kind ?
Got it, thanks
the module supports a random play function (command 0x18) but it needs to be sent through serial. The IO1, IO2, ADKEY1 and ADKEY2 pins won't let you get in that mode.
You know if an all in one board with a memory to contain audio files and a microprocessor to dictate commands exist? Thanks
you can build yours easily with any arduino (if dictate does not mean spoken command) 
This is all the things you can do without a microcontroller. If there is anything more you want to do, such as shuffle files, you will have to go through serial.
I already did it with arduino, I was wondering if I could do it with some sort of configuration like a script into the files folder ect..
My project consists in a small in size mp3 player mobile device that is able to play files randomly and I wrongly thought I could do it straight with the dfplayer mini without any microcontroller.
Thanks for the answer
Yes, I just figured it out. I think of using an attiny85 to do the job programming it with the arduino.
Thanks
the module does not offer this capability
