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

A hobbyist project called Birduino that combines a TonUINO open-source audio player, NFC-tagged bird playing cards, and an Arduino-based microcontroller to create an interactive bird call learning device. Tapping a bird card to the NFC reader triggers playback of that bird's vocalizations. The build covers hardware assembly (ATmega328P, RC522 RFID reader, MP3 module), C++ firmware configuration, audio sourcing from the Cornell Guide to Bird Sounds, NFC tag programming via a manifest script, and laser-cut clear acrylic enclosure fabrication. Practical lessons on prototyping board sizing, wire selection, and acrylic adhesive choice are shared.
