README.md提醒喝水器
本项目致力于复刻何同学视频中的智能杯垫，并添加更多的功能。才不是因为何同学做的开灯方案太没意义呢
方案设计
- 主芯片使用乐鑫ESP32，能在提供足够的性能的同时提供一个够用的互联网连接
- 检测杯子存在采用光电传感器，价格低廉，识别准确，美中不足需要在外壳上开孔
- 提醒方案采用Server酱的微信推送，同时板载蜂鸣器，可自行修改代码使用
- 外壳采用PETG打印而成，可自行选择其他材料以适应盛放开水的杯子
PCB设计
PCB使用Altium Designer和KiCAD设计。由于前后距离略长，PCB分为两块，一块为Type-C小板，一块为主PCB，两者通过杜邦线相连。推荐使用XH2.54系列端子以避免潜在的接触不良。推荐使用长度10或15厘米的线材。
外壳设计
外壳使用SoildWorks设计（大版本2020）。设计了上盖和底壳，两者通过长螺丝连接。长螺丝推荐使用M3 45mm，其他螺丝推荐使用M3 5mm。对于外壳的修改意见，欢迎提交issue和PR。
程序设计
程序基于ESP-IDF框架，并使用Arduino as a ESP-IDF component。预计后期将移除。
程序主要功能为设定报警时间，获取联网信息，获取在线时间并显示，计时杯子存在时间并推送等。
主要流程如下：

Questions
How big is the Type C Ext PCB?
It measures 23.4 × 35.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Type C Ext use?
4 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Type C Ext KiCad files?
From the kaidegit/DrinkAlarm repository on GitHub, at the commit this page was made from: the board is PCB/Type-C_Ext/Type-C_Ext.kicad_pcb and its schematic PCB/Type-C_Ext/Type-C_Ext.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Type C Ext design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
