Birduino Plays Bird Calls on Demand with NFC-enabled Cards hackaday.com

Hannah Robertson’s Birduino uses an Arduino Nano, an RC522 reader and an MP3 module to play bird calls when a user taps an NFC-stickered playing card. Each card’s ID is linked to recordings from Cornell’s collection of vocalizations for 908 North American bird species; the 54-card deck covers only a small subset.
