RGB controller

I. Function Introduction:
The WS2812 RGB LED can be adjusted via Bluetooth from a mobile phone and serial port from a PC, allowing users to customize preset RGB effects, colors, and brightness without programming. It also includes an external microphone for rhythmic effects.
II. Overall Design Scheme
: This design uses the STC32G12K128 chip as the MCU. Bluetooth communication is achieved using a ZX-D30 Bluetooth module. Reserved PC serial and Bluetooth serial ports allow for upper-level computer and APK development.
III. Hardware Introduction:
3.1 Power Input
: Power is a crucial component of the circuit. This project uses both Type-C and external DC power. Power can be switched via the SW1 switch when Type-C power is insufficient.
3.2 Wireless Communication :
Wireless communication is achieved using the ZX-D30 Bluetooth module.
3.3 Other:
A reserved microphone interface allows for rhythmic effects.
IV. Programming:
The program is burned using an STC-ISP with a running frequency of 24MHz. The burning file is attached.
V. Physical Demonstration:
A video demonstration is published on the Bilibili video platform.
