WS2812 Dot Matrix Light

Overview

I. Design Rationale:
Considering this is a beginner's first project, the difficulty needed to be limited; therefore, this 2812 dot matrix light was designed.

II. Wiring Design and Arrangement:
Double-layer wiring was used, with the 2812 colored lights arranged sequentially from left to right.

III. Physical Verification

Project Introduction
This design primarily utilizes the Air001 chip and WS2812 LED beads to create a pet light-up collar. It features a single button; long press to power on; single click to switch modes until power off; long press for stepless dimming while powered on; a flashing light indicates the maximum brightness.
**Cost:** Air001 chip 0.01; 12 WS2812 LED beads 1 yuan; battery 2 yuan; other components approximately 0.3 yuan; **

Lighting Effects:
** Timer Effect: 4 LEDs illuminate in a lap (Green: 30 minutes; Blue: 30-60 minutes; Yellow: 60-90 minutes; Red: 90 minutes and above)

Energy Saving Effect: Single LED illuminates in a lap (Green: 30 minutes; Blue: 30-60 minutes; Yellow: 60-90 minutes; Red: 90 minutes and above)

Fast Flash Effect:

Bounce Effect: Seven-color

Power-off Effect: 12 LEDs turn off sequentially
