Project Type: One-off project Expertise Level: Expert Industry: Entertainment / Live Events Duration: 4-8 weeks (with potential follow-up work) Remote OK: Yes Project Summary We operate physical escape rooms powered by Arduino-based puzzle boards. Each board sends a simple signal when a puzzle is completed. We need a web-based system that receives these signals, updates a session log or database, and sends the appropriate trigger to move the game forward. Also provides hints on each puzzle if needed. (e.g. unlock doors, play sound, etc.). This app will serve as the central controller for our games used by staff via tablet or desktop. What We Need Youll build a web app (dashboard + backend) that: - Accepts basic status messages from Arduino devices ('puzzle complete') - Updates a room session database in real-time - Sends commands to a main controller (e.g. via API call or MQTT) to trigger the next event - Includes a simple dashboard for staff to: - Monitor puzzle completion status - Start/reset rooms - Trigger hints or manual overrides Ideal Skills - Full-stack web development (Node.js, Express, React/Vue, or similar) - Experience integrating Arduino/microcontrollers with web servers (HTTP/WebSocket/MQTT) - Real-time communication systems - Firebase, PostgreSQL, or similar DBs design for operator dashboards (mobile-friendly) What Were Looking For - Someone who can propose the right architecture and lead development - Reliable, responsive, and capable of delivering a fast MVP - Experience with real-time systems or escape room tech is a big plus To Apply Send us: - A short message about your experience with Arduino or real-time dashboards - Examples of relevant projects - Your rate (hourly or fixed) If you're excited by live event tech and interactive experiences, wed love to hear from you!
