Child-Friendly Music Player Uses RFID

Hackaday reports on a clever solution to a modern parenting challenge: one electronics hobbyist built his young daughter a music player that skips the mouse and keyboard entirely. Using an Arduino Nano microcontroller and an RFID reader, the system recognizes toy dolls that have embedded tags, each tied to a different playlist stored on an SD card. When she places a doll on the player, the Arduino communicates with a DFPlayer module, which streams the music through a small speaker. The whole thing lives in a handmade wooden case—complete with volume control and a skip button for when a song becomes too annoying on repeat. It's the kind of elegantly simple interface that makes this kind of build so satisfying: no complicated menus, just place a toy and listen.
