If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
OpenHarmony 应用开发
物联网传感器接入
设备远程控制
环境数据采集
AtomGit 与 Git
PPT 与演示视频制作
The real friction is usually not library usage. It is validation, time allocation, and task framing.
主要难点是交付一个可运行的软硬件结合方案，而不只是做界面：作品需基于 OpenHarmony，同时完成环境与安全监测、设备控制和数据展示。还要在指定 AtomGit 仓库提交代码、可运行程序、设计材料和评审展示材料，并注意开源代码许可证限制。
This guide is the best pre-read if you want a cleaner start instead of trial-and-error.
How to learn feature engineering, validation, and competition workflow without heavy hardware.
