When [Neutrino-1] saw DFRobot’s DFPlayer module, he chose he wanted to make his own retro MP3 player. This small module comes loaded with a tonof fascinating capabilities such as EQ modification, volume control, and a 3 watt amplifier among other things. It can even play ads in between songs, ought to you want such a thing. Managing the DFPlayer module is simple utilizing serial
commands from a microcontroller, making it a practical subsystem in larger tasks, and a potential option to the popular VLSI chips or the hard to come by WT2003S IC. [Neutrino-1] does a good task walking readers through the build making it relatively easy to remix, reuse, and reshare. With the hardware sorted, all you’ve got to do is flash the firmware and load up an
SD card with some MP3s. There’s even a little Python GUI to assist you get your brand-new gamer up and running. [Neutrino-1] also introduces users to the U8g2 display library which he says is a bit more feature-rich than the common Adafruit SSD1306 library. Fantastic job [Neutrino-1] While you’re here, take a look at some of our other MP3 tasks.
