怎样用Arduino和手机控制LED

1、LED连接到Arduino和地面的第13管脚。连接模块到Arduino的Rx和模块到Arduino的的Tx的Rx端的TX。蓝牙模块的5蕺清寤凯V引脚连接到Arduino的5V和模块到Arduino的接地的接地

2、编码~上传给bluetoothlights.ino文件到你的Arduino记得上传前取下TX和RX引脚下面是bluet泠贾高框oothlights.ino文件，请自行用记事本编写，并保存~String readString;void setup() { pinMode(13, OUTPUT); Serial.begin(9600);}void loop() { while (Serial.available()) { delay(3); char c = Serial.read(); readString += c; } if (readString.length() > 0) { Serial.println(readString); if (readString == "1") { digitalWrite(13, 1); } if (readString == "6") { digitalWrite(13, 0); } if (readString == "2") { digitalWrite(13, 1); delay(1000); digitalWrite(13, 0); delay(1000); digitalWrite(13, 1); delay(1000); digitalWrite(13, 0); delay(1000); digitalWrite(13, 1); delay(1000); digitalWrite(13, 0); delay(1000); digitalWrite(13, 1); delay(1000); digitalWrite(13, 0); delay(1000); digitalWrite(13, 1); delay(1000); digitalWrite(13, 0); delay(1000); } if (readString == "3") { digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); digitalWrite(13, 1); delay(400); digitalWrite(13, 0); delay(400); } if (readString == "4") { digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); digitalWrite(13, 1); delay(85); digitalWrite(13, 0); delay(85); } readString = ""; }}

3、下载APK安装它。确保Bluetooth已打开您的手机上，并且蓝牙模块已与设备配对。如果它要求一个密钥，那就1234好了~

4、当然首先你要熟悉一下Arduino，去搜索一下，官网下载~

5、进入官网后，点击download处下载

6、light.apk下载地址街鹏袷敖链接：http://pan.baidu.com/s/1miGqQla 密码：5j5g大小1.44兆

7、最后打开应用程序，连接你的蓝牙模块，并enjoy！
