“Mp3 player may sound quite outdated. Smartphones can do much better than this! With all those apps and streaming services, you don’t even need to download any music or song.
But when I encountered the DFplayer module it really excited me with a bunch of features. From volume control, a 3W amplifier, equalizer, ability to play ads between the mp3 files, and much more. I wanted to explore all these features and put them to good use in a single device. So this MP3 player was a perfect choice.
The end product was quite interesting to use with the following features:
EQ Adjustment
Volume Control
Pause/play MP3 files
Next/previous
2 screen navigation
rechargeable battery
