ESPuino - RFID cards kids player

[tueddy]

Hi,

we are using your library in ESPuino :

"The basic idea of ESPuino is to use RFID-tags to direct a music-player. Even for kids this concept is simple: place an RFID-object (card, character) on top of a box and the music starts to play stuff from SD or webradio. Place another RFID-object on it and anything else is played. Simple as that."

ESP32-A2DP is used here both sink and source, BT-Sink for using the box as Bluetooth speaker, BT-Source for headsets

Thank's for this great library!
