Charlie's RFID Teddy Bear from MAKE Volume 28

Science communication designer David Harris wanted to make a unique toy for his nephew Charlie, who was born with cerebral palsy. Charlie’s vision is poor but he’s very tactile and auditory, so David designed a location-aware teddy bear that reads RFID tags and plays different customizable sounds depending on where it is or what object it’s near. An Arduino embedded in the bear uses an RFID reader to recognize nearby RFID tags, then uses an audio shield attachment to play corresponding audio files stored on an SD memory card.

David shared his build instructions with us on the pages of MAKE Volume 28, the Toys and Games issue, and we’ve shared the full build with you on Make: Projects. To make gathering supplies for the build a breeze, the Maker Shed has put together the RFID Teddy Bear Project Bundle, which includes all the materials you need except for the bear, the velcro, and sewing thread. Time to play!
