nfcAudio is an MP3 player, with audio files selected thanks to an NFC tag placed on top of it. I build this two years ago for my kid so he can play by himself his preferred nursery rhymes and songs, it is still used at least once a week :-)

It is powered by an ESP8266 to play audio from a remote server, an I2S DAC driving the speaker and an NFC reader. Thanks to WiFi we can use it to play local files or any webradio stream from the Internet.
