Child-Friendly Music Player Uses RFID

A DIY music player built for a young child uses RFID tags embedded in small dolls to trigger playlists. An Arduino Nano reads the tags via an RC522 reader and communicates over serial with a DFPlayer Mini module, which plays MP3 files from an SD card through a small speaker. The whole build is housed in a wooden case with a volume knob and skip button.
