DFcontroller

Receives SD card sound file data of Arduino sound module dfplayer through Bluetooth and uses the data to remotely control dfplayer in an mp3 player environment.Intuitive control by using the track name by importing the track list.-Bluetooth 2.0 Classic HC-06 module-Bluetooth 4.0 BLE AT-09 module-ESP8266 NodeMc-ESP32 DevKit1.HC06/AT09 + DFPlayer mini2.HC06/AT09 + Arduino + DFPlayer mini3.
