介绍
首先，介绍一下本次项目-我的结课作业
经过一学期的学习，也是多多少少了解了一点关于Arduino的东西了，现在我们开始介绍我和我搭档的大作业，也希望这个作业可以帮助到你们。
功能介绍
由于老师提供的开发板是Arduino UNO R3，根本不具备wifi或者是蓝牙功能，这就是的我们的项目很难有特点。
于是我们开始专研ESP-01s(下面简称ESP)和Arduino的串烧，网络端向ESP发送数据再由ESP向Arduino发送处理后的数据，这样就可以控制我们的主板了。
原谅一下站主没有找到Arduino的Fritzing插件，站主这几天也比较忙没有去画这些插件。

很明显我们这个产品是一个超市系统，简述产品功能如下：

模块与实现功能：
| 序号 | 主--模块 | 次--模块 | 作用 |
| 1 | U型光电传感器 | 有源蜂鸣器(HH) | 检测客流量，模拟“欢迎光临” |
| 2 | 干簧管 | U型发光电传感器、有源蜂鸣器(JB) | 检测用户是否逃单，有则报警 |
| 3 | LED--绿灯 | （APP直接操控） | 上班打卡，上班常亮，下班关闭 |
| 4 | 普通LED | （APP直接操控） | 模拟店内的所有照明(可添加) |
| 5 | 温度报警器 | LED(红)、有源蜂鸣器 | 报警 |
| 6 | 烟雾报警器 | LED(红)、有源蜂鸣器(JB) | 报警 |
| 7 | 温度传感器 | LED(红)、有源蜂鸣器 | 报警 |
| 8 | 28BYJ-48步进电机 | ULN2003、继电器 | 开关门 |
| 9 | 按钮 | 重启Arduino(记录的数据不会重置) | 关闭报警(报警不能由系统关系) |
| 10 | 光敏传感器 | 普通LED | 光线充足自动关灯 |
| 11 | 继电器 | 由APP直接控制反馈数据给Arduino |

}源码都有注释，Arduino和ESP的接线图在图一
记住：ESP和Arduino的频率必须一致，不然就会丢包。ESP供电是3.3v，ESP供电是3.3v，ESP供电是3.3v。
