    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. ( http://www.dfrobot.com/index.php?route=product/product&product_id=1121 ). 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.
