## Arduino程序 ##

#include <SoftwareSerial.h>//加载软串口库
    #define Relay 4 //继电器引脚为4号引脚
    SoftwareSerial mySerial(2,3);//设置2、3引脚为软串口 2-->rx  3-->tx
    void setup()
    {
       mySerial.begin(9600);//串口初始化波特率 9600
       Serial.begin(9600);
       pinMode(Relay,OUTPUT);//配置引脚为输出模式
       digitalWrite(Relay,HIGH);
    }
    void loop()
    {
      while(mySerial.available())//检测串口是否有数据
       {
         char c=mySerial.read();//将串口数据读取后赋给字符 c
         Serial.println(c);
          if(c=='a')
            {
              digitalWrite(Relay,LOW);
              Serial.println("ON");
            }else if(c=='b'){
              digitalWrite(Relay,HIGH);
              Serial.println("OFF");
            }
       }
    }

## 手机APP ##

首先打开蓝牙，点击搜索，找到HC-06配对 默认密码：1234

配对成功后，打开APP，点击搜索蓝牙

在已配对蓝牙设备中点击HC-06，进入蓝牙通信界面

可以考的信息提示连接中，等待连接成功后，点击继电器开关按钮，蓝牙开关制作完成！

## 提示 ##

1、配对过程中，蓝牙连接未建立前，Hc-06模块上的指示灯会闪烁，配对成功后，模块指示灯常亮  
2、如果APP上提示创建连接失败，那么点击按钮重新建立连接
