ritual table - rfid puzzle

2024 · HARDWARE · CIRCUIT DESIGN · INTERACTIVE DESIGN

physical objects. real placement. no buttons.

prototype puzzle hardware for an escape room installation. five RFID readers embedded in a wooden table detect the placement of five designated objects. correct placement lights the corresponding candle. incorrect placement triggers a rapid flash across all five.

designed and built from scratch: RFID reader integration, microcontroller programming, and a low-voltage control circuit for 12V light bulbs.
