The servo exercise used this table to map a 0.5–2.5 ms high time within a 20 ms period onto 0°–180°. It is a Timer/PWM setup reference, not an oscilloscope measurement.舵机练习用这张表把 20 ms 周期内的 0.5–2.5 ms 高电平时间对应到 0°–180°。它是配置 Timer/PWM 时使用的参数参考，不是示波器实测波形。

Arduino Breadboard Two-Digit Seven-Segment CounterArduino 面包板两位数码管计数器
For MEC104 Group A17, I handled most of the two-digit counter’s wiring, firmware, and debugging. Testing the display segments and measuring switch contacts resolved faults that code changes had not.我承担 MEC104 A17 组两位计数器的大部分搭建、编程与调试。数码管接法和六脚按键先后出问题，我通过逐段试灯、测量开关通断，把显示、暂停和复位调通。

06.01Image图像Two BCD display paths in the report两条 BCD 显示链的报告示意图
The report written by my teammates fans an Arduino Uno into two decoder/display branches and places two switches alongside them. It records the system topology; the breadboard I built and integrated used an Arduino Nano.组员撰写的作业报告从 Arduino Uno 分出两路译码/显示支路，并在旁边接入两个开关。它记录的是系统拓扑；我实际联调的面包板使用 Arduino Nano。

The 17-second clip only captured changing digits只留下数字变化的 17 秒现场视频
The clip only shows both digits changing while the Arduino Nano remains powered; it does not capture a button press. Pause and reset passed the classroom demonstration, but this video cannot serve as visual evidence for them.镜头只拍到了 Arduino Nano 上电后两位数字持续变化，没有拍下按键操作。暂停和复位最终通过了课堂演示，但不能拿这段视频充当它们的影像证据。

This slide defines the group-number build with two digits, rollover after 17, plus pause and reset. Counting through 99 was a separate version that I produced by changing the threshold, then flashed and demonstrated independently.这页课件定义了小组号版本，两位显示，到 17 后归零，并支持暂停和复位。计数到 99 再归零是另一个改完阈值后单独烧录、单独验证的版本。

06.04Image图像The three-stage display path I only understood later我后来才看懂的三段显示链路
The slide reduces the system to Arduino, BCD decoder, and seven-segment display. During the project I was connecting those stages one at a time; only later did I join software state, decoder outputs, and LED current into one explanation.课件把系统压成 Arduino、BCD 译码器和数码管三段。项目当时我只是在逐段接通；现在回看，才真正把软件状态、译码输出和 LED 电流路径连成一条链。

06.05Image图像BCD logic does not define the current directionBCD 逻辑之外，还有电流方向
The slide marks A-D inputs, a-g outputs, power, and segment resistors around a 7447-style device. Four BCD bits select a number; whether it lights still depends on output polarity, the display common, and the actual current path.这页标出了 7447 类器件的 A-D 输入、a-g 输出、供电和段限流。四位 BCD 只决定数字；显示能否点亮，还取决于驱动极性、公共端和实际电流路径。

06.06Image图像A six-pin switch mapped with a multimeter靠万用表摸清的六脚按键
Without a matching datasheet, the six pins produced no response, unstable readings, and repeated triggers. I borrowed a multimeter and checked continuity pair by pair before reconnecting the pause and reset functions.没有对应数据手册时，六只脚让我遇到没反应、乱跳和重复触发。我借来万用表逐对测通断，先确认按下前后的内部连接，再把暂停和复位接回程序。

06.07Image图像From a one-digit demo to two-digit integration从一位 demo 到两位联调
Development roughly followed the course sequence. I read the material, ran a one-digit BCD example, wired two digits, split units and tens, added the buttons, then integrated the system. The two demo sketches were early checkpoints, not the final program.实际开发大致沿着课件顺序推进。我先读资料和跑一位 BCD 示例，再铺两位接线、拆分个位与十位、加入按键，最后联调。两份 demo sketch 都只是前期检查点。

06.08Image图像The CD4511 simulation omitted a polarity assumption漏掉极性前提的 CD4511 仿真
TinkerCAD uses a CD4511 to drive a common-cathode display, while the physical LS47 path was intended for common-anode operation. Both decode BCD, but they cannot use the same common-pin connection; that mismatch produced the dark or scrambled display.TinkerCAD 用 CD4511 驱动共阴数码管，实物的 LS47 路径却面向共阳显示。两者都做 BCD 译码，但不能共用同一个公共端接法；这正是当时不亮/乱码故障的来源。

06.09Image图像Two decoder branches in the A17 reportA17 报告中的双译码支路
The cropped report places two decoders between an Arduino Uno and two displays, with resistors and switches nearby. It captures the intended branch relationship; the circuit I built and integrated on the bench used an Arduino Nano.报告裁图把两颗译码器放在 Arduino Uno 与两位数码管之间，旁边还有电阻和开关。它说明了预期支路关系；我实际搭建和联调的是 Nano 面包板版本。

06.10Image图像How one state becomes units and tens一个状态怎样拆成个位和十位
`Num % 10` extracts units and `(Num / 10) % 10` extracts tens. Each result selects a four-bit BCD row for its own decoder; this was the two-digit split I learned while building the project.`Num % 10` 取个位，`(Num / 10) % 10` 取十位；两个结果各自查一行四位 BCD，再送进两颗译码器。这是我当时边查资料边学会的两位显示拆分。

06.11Image图像A button screenshot that cannot settle the final wiring无法替最终硬件下结论的按键截图
The excerpt checks switch 1 with HIGH and switch 2 with LOW, while the report also mentions a pull-up. Both buttons passed the classroom demonstration, but without the final wiring and source this image cannot prove a tidy polarity or debounce implementation.截图里 switch 1 用 HIGH，switch 2 用 LOW，报告文字还提到上拉。最终两个按键确实通过了课堂演示，但缺少最终源码与接线，不能据此补出一套整齐的极性或消抖实现。

Claude Chime Power BoardClaude Chime 电源板
For an independent hardware commission from Accele AI, I designed and hand-assembled Claude Chime's ESP32 peripheral power board. The roughly 28 × 27 mm PCB combines single-cell charging, two separate boost rails, gated battery-voltage sensing, and a 5 V push-pull solenoid driver. I completed basic power-up and interface checks; the client's firmware engineer later reported normal complete-device operation.受 Accele AI 委托，我独立设计并手工焊接了 Claude Chime 的 ESP32 外围电源板。约 28 × 27 mm 的 PCB 集成单节锂电池充电、两路独立升压、受控电池电压采样和 5 V 推拉式电磁铁驱动。我完成了基础上电与接口测试，客户固件工程师随后反馈整机运行正常。
