# 物联智能开关灯工程(一个极客AGeek开源)
该工程是基于esp32C3使用IDF v5.2开发的一个物联开关灯模块。
使用esp32c3联网后对接巴法云MQTT服务器再对接天猫精灵。
通过巴法云mqtt通信控制一个mg90s的舵机来转动对应角度来替代手指去开灯或者关灯。
可以和天猫精灵联动，对天猫精灵说“天猫精灵 开灯/关灯”来控制舵机开关灯。
## 如何使用
### 硬件需求
首先准备硬件如下:
1. ESP32C3开发板或者自己绘制的板子，需要能进行烧录。
2. mg90s的舵机一个，需带一个塑料转子。
3. 2.54公对母杜邦线。
4. 502胶水或者强力泡棉双面胶等或其他结构固定。
5. 一条USB线和5v充电插头。
6. 家用的2.4G wifi或者热点。
组装图如下
### 如何配置工程？
#### 配置idf开发环境
首先需要下载vscode
然后安装vscode，注意需要勾选这几个框方便打开文件夹工程。
可以下载中文插件再重新打开就是中文页面
在vsdode中下载idf插件
在vscode左侧乐鑫图标打开idf
选择安装idf开发环境
选择乐鑫服务器
选择版本V5.2
不同电脑环境不一样，有可能会出现idf安装失败的情况
那就只能按报错信息去百度查找原因
然后需要先删除原本的idf下载目录的东西，卸载插件重新安装，如果还是不行那就安装旧版本或者另一个版本
安装成功后可以选择工程文件夹打开工程
#### 注册巴法云物联平台
注册巴法云

选择MQtt设备云创建主题
roomLight002 appSend appReceive
打开mqtt_app.c
复制私钥到 .credentials.client_id
``` c
mqtt_app_t mqtt_bemfa=
{
.mqtt_cfg = {
.broker.address.uri = "mqtt://bemfa.com:9501/",
.credentials.client_id = "私钥",
.network.disable_auto_reconnect = true,
},
.event_handler=mqtt_event_handler,
.topics={"roomLight002","appSend","appReceive"},
.state=mqtt_state_stop
};
```
打开wifi_connect_default.c
填写家里或手机的wifi热点名称和密码
``` c
#define CONFIG_EXAMPLE_WIFI_SSID "2.4G wifi名称"
#define CONFIG_EXAMPLE_WIFI_PASSWORD "wifi密码"
```
mg90s舵机默认是90度,安装塑料的转子在90度时贴合到灯的开关侧边
默认开灯是先转动到90度300ms后转到45度500ms后转动回90度
默认关闭是先转动到90度300ms后转到135度500ms后转动回90度
如果这个控制逻辑和你实际安装到灯的开关不一样时需自行修改
打开 mg90s.c
修改 mg90s_180_switch_room_light函数
``` c
/**
* @brief 功能介绍：设置舵机转动实现开关灯
* @param 参数：mg90s
* @param 参数：is_on
*/
void mg90s_180_switch_room_light(mg90s_180_t* mg90s ,uint8_t is_on)
{
if(is_on)
{
ESP_LOGI(TAG, "room_light_on");
mg90s_180_set_mode(mg90s,mg90s_angle_90);
vTaskDelay(pdMS_TO_TICKS(300));
mg90s_180_set_mode(mg90s,mg90s_angle_45);
vTaskDelay(pdMS_TO_TICKS(500));
mg90s_180_set_mode(mg90s,mg90s_angle_90);
}else
{
ESP_LOGI(TAG, "room_light_off");
mg90s_180_set_mode(mg90s,mg90s_angle_90);
vTaskDelay(pdMS_TO_TICKS(300));
mg90s_180_set_mode(mg90s,mg90s_angle_135);
vTaskDelay(pdMS_TO_TICKS(500));
mg90s_180_set_mode(mg90s,mg90s_angle_90);
}
}
```
尝试编译
然后串口下载到开发板
把开发板的
IO5 5V GND
和舵机的线接上
``` shell
IO5-->橙色线
5V-->红线
GND-->棕线
```

可以在巴法云服务器管理界面对应主题直接发送"on"
向对应的巴法云mqtt服务器的主题例如roomLight002打开灯时的日志
``` shell
I (155151) mqtt_example: MQTT_EVENT_DATA
TOPIC=roomLight002
DATA=on
I (155151) mg90s: room_light_on
```
收到打开指令后，esp32c3开发板会控制舵机转动到45度或者135度后再回到90度。
可以在巴法云服务器管理界面对应主题直接发送"off"
向对应的巴法云mqtt服务器的主题关闭灯时的日志
``` shell
TOPIC=roomLight002
DATA=off
I (194781) mg90s: room_light_off
```
收到关闭指令后，esp32c3开发板会控制舵机转动到135度或者45度后再回到90度。
当测试舵机能正确转动
再使用胶水或者其他固定方法让舵机贴合在开关侧边
### 对接天猫精灵
如果需要接入天猫精灵语音控制
请在天猫精灵app搜索巴法云
然后按巴法云物联平台的帮助教程操作
绑定自己的巴法云账号
绑定完成后可以在天猫精灵app进行智能灯的控制
如果有天猫精灵已经联网
可以直接对天猫精灵说“天猫精灵 开灯”或者“天猫精灵关灯”
天猫精灵会自动向绑定好的巴法云的主题推送“on”和“off"
最终实现语音控制舵机转动来按下灯的开关。
### 舵机无法转回90度
如果舵机开灯或关灯完成后转回90度后还在持续嗡嗡的转
就是舵机的塑料转子顶住了灯的开关没转回90度
需要适当的把塑料的转子刮去一些或者剪短一些。
需要按自己实际安装情况处理
