One Sensor / IoT Demo That Shows One Real Signal

一个能显示真实信号的 Sensor / IoT 小 Demo

Student: Kelvin Chan

Runtime: https://kelvin90.homelinked.tech/

Small Success Direction: It shows one real signal. · 它能显示一个真实信号。

Current Learning Status: CHOOSING → MAKING → TRIED → CONNECTED → READY_FOR_NEXT

The system may be complex. Kelvin’s next step should be simple.

系统可以很复杂,但 Kelvin 的下一步应该很简单。

What Is a Good First Success? · 什么是好的第一次成功?

Kelvin chooses one sensor, one hardware signal, one CAD / hardware object, or one simple IoT input, and makes the signal visible through a page, photo, data log, chart, terminal output or short demo.

Kelvin 选择一个传感器、一个硬件信号、一个 CAD / 硬件对象,或一个简单 IoT 输入,并通过页面、照片、数据记录、图表、终端输出或短 Demo 让这个信号被看见。

One input
+ one visible signal
+ one simple explanation
+ one test by another person
+ one improvement
+ one handoff note

Candidate Small Demo Directions · 候选小 Demo 方向

Kelvin can choose one. The first version can be manual, simulated, photo-based, Arduino / STM32 based, or web-based.

Kelvin 可以选一个。第一版可以是人工、模拟、照片、Arduino / STM32,或网页展示。

This Five-day Cycle · 本次五日循环

Day Action Success
Day 1 — Choose
找到
Choose one small signal, sensor, CAD object or hardware question. Kelvin can explain what signal or object he wants to make visible.
Day 2 — Create
做出
Create one simple visible result: screenshot, photo, value display, mock chart, terminal output or demo page. There is one visible artifact.
Day 3 — Check
试用
Try it once and ask one person to read, watch or use it once. One useful part or one confusing part is found.
Day 4 — Connect
连接
Put the result into the existing Runtime with a short explanation and one sample file or image. Another person can open the Runtime and see what was made.
Day 5 — Continue
留下
Fix one issue and write a 3–5 step Quick Start and Handoff. The next person knows how to repeat or improve the demo.

What I Am Making · 我正在做什么

AI+HK Personal Capability Kit
Sensor / IoT Signal Demo R0.1

A small demo that helps a user:
1. see one real signal or object;
2. understand where the signal comes from;
3. know what tool, sensor or design was used;
4. see one result;
5. know the next step.

This can be a hardware photo, sensor reading, C/C++ output, Arduino / STM32 demo, Bluetooth data path, CAD object explanation, circuit / PCB concept, or a simple webpage.

这可以是硬件照片、传感器读数、C/C++ 输出、Arduino / STM32 Demo、蓝牙数据路径、CAD 对象说明、电路 / PCB 概念,或简单网页。
