A card-triggered audio player for [learning] the birds

Maker Hannah Robertson has created Birduino, a card-triggered audio player for learning bird vocalizations. Tap a bird card on the reader and it plays back that bird's calls—you can deliberately study each bird's unique sounds, or draw a random hidden card and guess which bird you're hearing. The cards use NFC tags programmed with audio data, per Adafruit Blog.
