Including an audio option with an electronic or Internet-of-Things (IoT) project is often an ideal addition. However, microcontrollers cannot process MP3 files, <\/span>which is<\/span> the most common audio file format. Fortunately, there is a solution. <\/span><\/p>\n

It is possible to play<\/span> MP3 audio files on Arduino using dedicated MP3 decoders like the DFPlayer Mini or MP3-TF-16P.<\/span><\/p>\n

DFPlayer Mini is a popular original MP3 decoder for Arduino. But if you ordered the DFPlayer Mini module online, you may have received the MP3-TF-16P instead of the original DFPlayer. Both modules look identical and have the same pin configuration but use different chipsets. <\/span><\/p>\n

The issue is if you<\/span> try to run audio files using the MP3-TF-16P module and Arduino\u2019s libraries for the DFPlayer Mini. The MP3-TF-16P uses a different chipset despite having the same chipset as the DFPlayer Mini. The popular libraries for the DFPlayer Mini fail to run on MP3-TF-16P because of the different chipset features.<\/span><\/p>\n

In this project, we<\/span>\u2019ll explain how to play MP3 files on Arduino using the MP3-TF-16P module. The code provided here also works on the original DFPlayer Mini, as both chipsets have the same instruction set.<\/span><\/p>\n

    Circuit connections<\/span><\/strong><\/h3>\n

    We\u2019ll need to interface the DFPlayer Mini or the MP3-TF-16P with Arduino to play MP3 audio files on Arduino. Both modules have the same pinout which is shown in the below image.<\/p>\n
