背景：因为住在实验室，灯的开关离我的床很远，所以不想每次睡觉时还要下床关灯（其实就是懒）
先上视频预览一下：
智能开关灯
材料准备：MG90s舵机一个，esp8266 node mcu一个，充电宝一个，可传输数据的数据线一根，可能还需要热熔枪（具体看自己的插座布局）
先上arduino代码：
#define BLINKER_WIFI#define BLINKER_PRINT Serial#define BLINKER_MIOT_LIGHT#include <Blinker.h>#include <Servo.h>char auth[] = ""; //点灯Keychar ssid[] = "";//wifi名称char pswd[] = "";//wifi密码BlinkerButton Button1("test1"); //blinker按键键名BlinkerButton Button2("test2"); //blinker按键键名Servo servo_16; //舵机输出口 GIPO16 D0口bool oState = false;//按键1按下后执行该函数void button1_callback(const String & state) {BLINKER_LOG("get button state: ", state);// digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));servo_16.write(45); //舵机旋转角度 具体参数需要结合自身情况修改delay(1); //给一个小延时delay(1000); //舵机动作后延时一会回到初始位置servo_16.write(95); //设置该角度方便手动开关灯 就是开完灯舵机归位}//按键2按下执行该函数void button2_callback(const String & state) {BLINKER_LOG("get button state: ", state);servo_16.write(139); //同上一样的思路delay(1);delay(1000);servo_16.write(95); }//小爱电源回调函数//里面同样设置舵机的动作void miotPowerState(const String & state){BLINKER_LOG("need set power state: ", state);if (state == BLINKER_CMD_ON) {// digitalWrite(LED_BUILTIN, HIGH);servo_16.write(45);delay(1);delay(1000);servo_16.write(95);BlinkerMIOT.powerState("on");BlinkerMIOT.print();}else if (state == BLINKER_CMD_OFF) {// digitalWrite(LED_BUILTIN, LOW);servo_16.write(139);delay(1);delay(1000);servo_16.write(95);BlinkerMIOT.powerState("off");BlinkerMIOT.print();}}void miotQuery(int32_t queryCode){BLINKER_LOG("MIOT Query codes: ", queryCode);switch (queryCode){case BLINKER_CMD_QUERY_ALL_NUMBER :BLINKER_LOG("MIOT Query All");BlinkerMIOT.powerState(oState ? "on" : "off");BlinkerMIOT.print();break;case BLINKER_CMD_QUERY_POWERSTATE_NUMBER :BLINKER_LOG("MIOT Query Power State");BlinkerMIOT.powerState(oState ? "on" : "off");BlinkerMIOT.print();break;default :BlinkerMIOT.powerState(oState ? "on" : "off");BlinkerMIOT.print();break;}}void dataRead(const String & data){BLINKER_LOG("Blinker readString: ", data);Blinker.vibrate();uint32_t BlinkerTime = millis();Blinker.print(BlinkerTime);Blinker.print("millis", BlinkerTime);}void setup(){Serial.begin(115200);BLINKER_DEBUG.stream(Serial);// 初始化pinMode(LED_BUILTIN, OUTPUT);servo_16.attach(16);// servo_16.write(90);//上电时舵机归零垂直digitalWrite(LED_BUILTIN, HIGH);// 初始化blinkerBlinker.begin(auth, ssid, pswd);BlinkerMIOT.attachQuery(miotQuery);Blinker.attachData(dataRead);BlinkerMIOT.attachPowerState(miotPowerState);Button1.attach(button1_callback);Button2.attach(button2_callback); }void loop(){Blinker.run();}
char auth[] = ""; //点灯Key
char ssid[] = ""; //wifi名称
char pswd[] = ""; //wifi密码
分别是你在点灯科技软件中申请的点灯key,以及wifi名称和密码（必须是2.4GHZ的wifi）
代码可以实现舵机开完灯或者关完灯后，自动返回初始位置，无需手动调整。当然还可以接入点灯科技进行控制，详细的可以看我下面的教程。
