    Took some time to figure out, but it's now working very good. Powerfull output on a satisfying noise level. Plays ordinary MP3 and WAV files. When Googeling on DFPlayer mini, you will find enough documentation and an Arduino library. ( ). The sketches need some modification to get them running on an UNO (change realy to software serial pins) Very important!!!: To suppress the anoying bouncing noise you need to connect the RX and TX pins via a serial 1K resistor.

    Took a bit of work to figure it out. Files must be mp.3 or wav. File structure is folder = 01, 02 , 03... Files must be 0001.mp3, 0002.mp3 ... Still haven't totally figured out the speaker output. It does not work as shown! I connected speaker 1 and ground to a 16 ohm speaker and got reasonable volume. Did not work between speaker 1 & speaker 2 as shown. Suggest you run an external amp.

    Nice and cheap MP3 player. Please read the technical information at It can be used with and without Arduino to control playing MP3 files.. MP3 files need to stored in the root directory.
