此项目为本人在参与Vision Board 创客营活动第二阶段（应用作品设计）过程中所产出的内容。主要内容是实现 LED 矩阵实时响应 AprilTag 的坐标进行同步移动。
This project is an output of my participation in Vision Board Creator Camp Phase II (Application Design). The main content is to realize the synchronized movement of the LED matrix in real time in response to the coordinates of the AprilTag.
“Vision Board 创客营”是由电子发烧友论坛与 RT-Thread 共同主办的围绕新品 Vision Board 开发板进行一系列评测的活动。
The "Vision Board Creator Camp" is an event co-sponsored by https://bbs.elecfans.com and RT-Thread, featuring a series of reviews around the new "Vision Board" demo board.
总共涉及三款硬件，具体内容为：使用 Vision Board 作为上位机，并通过 OpenMV 程序获取 AprilTag 实时坐标、再通过 UART 串口通讯发送坐标信息给下位机；Arduino(Uno) 作为下位机接收坐标信息并将信息转化为 LED 矩阵坐标，再通过 FastLED 库实现对 WS2812b 灯带的 LED 操控。
In total, there are three pieces of hardware involved, as detailed below: Using Vision Board as the host computer, and through the OpenMV program to obtain the AprilTag real-time coordinates, and then through the UART serial communication to send coordinate information to the lower computer; Arduino(Uno) as the lower computer to receive coordinate information and information into the LED matrix coordinates, and then through the FastLED library to achieve the LED manipulation of the WS2812b.
由于手头上的 WS2812b 灯带连接触点氧化、无法焊接导线从而成为方形矩阵，故暂时放弃二维矩阵的模式，转而以初步实现一维矩阵（5 个 LED 灯珠）为目标。
Since the existing WS2812b strip has oxidized connecting points and it is not possible to solder wires to make a square matrix, the two-dimensional matrix model has been abandoned for the time being in favor of a preliminary realization of a one-dimensional matrix (5 LED beads).
