- Operation and Usage
After successful flashing, press the Reset button on the XIAO-ESP32-S3 to enter "Monitoring Mode."
Upright Position (Warm Light Mode) : When the bottle is upright, the LED strip displays a Warm Yellow Breathing light. The slow breathing rhythm creates a peaceful atmosphere.
Inverted Position (Idle Alert) : When flipped upside down, the light switches to a Red Breathing effect.
Shake Trigger (Emergency Response) : Shaking the bottle while inverted enters the "2-Minute Flash Mode." The LEDs will flash rapidly in red for 120 seconds, even after shaking stops.
Instant Override : Flipping the bottle back to the upright position at any time will immediately switch the light back to the Warm Yellow Breathing effect.
Flash firmware to your device (in-app tool on CodeCraft Hub).
- Future Extensions
In addition to basic posture feedback, the following functions can be further expanded:
Sleep Timer : Auto-extinguish after 30 minutes of being upright, serving as a bedside sleep lamp.
Stress Relief Tool : Change flash frequency or colors based on shaking intensity as a visual feedback for emotional regulation.
Logistics Impact Monitor : Place inside fragile packaging; a persistent red flash can mark packages that were violently shaken or inverted during transit.
