[项目] 基于树莓派Pico的温度提醒装置

本帖最后由创客维克多于 2024-1-9 10:33 编辑

一次偶然的机会，买了3块树莓派Pico，但是后来感觉没啥用，就压箱底了。直到这次DF社区发起的树莓派活动，于是想起了箱底的Pico，就拿来试试看。没想到还挺不错的，最棒的是它自带温度传感器，直接用串口读取非常方便。但是奇怪了，为什么总是上传不了程序呢？经过几周的折腾，后来发现是Mind+版本的问题，更新到V1.8-RC1.0之后就解决了上传不了程序的问题了。

   本来想用RX711称重模块做一个称重作品的，结果测试了一个午都不成功，原因是称重模块的读取数据很不稳定而且跨越的幅度很大，所以放弃了。
   入冬以来，学校很多小朋友感冒请假没来上学，很多都是因为着凉了。于是我就想到做一个出门防着凉提醒装置，放在家门鞋柜上面，可以在出门前提醒小朋友。
