Transform holiday spaces with interactive lighting using this professional-grade Christmas decor kit. Centered around Bluno BLE control and WS2812 addressable LEDs, it enables real-time phone programming of each LED's color and rhythm. The integrated audio analyzer (DFR0126) syncs lights to music beats—perfect for dynamic Xmas displays, Arduino learning, and immersive installations.

Core Capabilities
-
Real-Time Phone Control: Customize colors/patterns via Bluetooth using the DFRobot App (pre-loaded with 8+ holiday themes like "Snowfall Pulse" and "Gift Unwrap")
-
Music Visualization: Audio analyzer converts sound frequency bands into cascading light effects (e.g., bass → red waves, treble → blue sparks)
-
Modular Design: Detach segments for tree ornaments or wreaths; reuse Bluno + sensors for robotics/IoT projects
-
Plug-and-Play Setup: IO Expansion Shield simplifies wiring—no soldering required
Applications
-
Dynamic Holiday Displays: Wrap trees, outline rooftops, or create synchronized light shows reacting to Christmas carols
-
Educational Workshops: Teach BLE communication, audio processing, and PWM control via Arduino (sample code provided)
-
Interactive Art: Build sound-reactive installations (e.g., clapping-triggered gift box illuminations)
-
Retail & Event Zones: Deploy in malls or parties as crowd-engaging attractions (voice-controlled color shifts)
