From the project

BailaBox - RFID enabled, ESP32-based music toy for kids that works with Home Assistant and network speakers.

BailaBox is an open-source, token-controlled music player interface built around an ESP32-S3, ESPHome and Home Assistant. Place a printed RFID token on the reader to start its assigned song or playlist, remove it to pause, and use the physical buttons and rotary encoder for playback and volume control.

This is a personal hobby project shared for other makers to study, modify and build. It is not a finished commercial product or a certified children's toy.
