STM32项目分享：基于STM32的智能饲养机 - 实践
“我们不做一锤子买卖，只做工艺成长的长期伙伴！”
目录
一、视频展示
基于STM32的智能饲养机 -视频分享
二、项目简介
题目：基于STM32的智能饲养机
主控:STM32
显示:OLED显示屏
HX711重量传感器
光检测模块：光照传感器
DS1302时钟模块
JQ8400语音播报
舵机（投喂）
wifi通信:esp8266云智能
功能：
1、实时监测当前环境光强度，实物重量，时间。
2、可通过按键设置实物重量阈值，做到定量投喂
3、wifi模块可连接手机然后经过手机查看当前信息信息控制投喂。
4、可按键设置定时投喂。
5、到达定时时间，语音播报唤醒宠物过来吃食物，
6、屏幕显示重量，时间。光照等数据。
三、原理图设计
四、PCB硬件设计
五、程序设计
