Secret Signals (Gesture Hero)
Overview
Build gesture control with a camera model that detects simple hand movements and triggers CodyNick actions.
What Students Do
Collect a few gesture samples, train a lightweight recognition model, and map results to LEDs, buzzers, or fans. Iterate to improve reliability and reduce false triggers.
Outcome
A gesture-controlled demo where moving a hand turns devices on or off and adjusts modes safely.
Requirements
- CodyNick gadget with LEDs or relay output
- Laptop with webcam and block-coding access
- Clear, easy-to-remember gesture set (2–3 gestures)
