安卓手机控制Arduino+HC-05蓝牙模块

先把串口接收代码烧入UNO单片机：

代码中大概功能是，循环接收串口信号，然后根据接收到的信号数值转动舵机角度

#include <Servo.h>String angle = "";Servo myse;void setup(){myse.attach(7); //设置舵机口myse.write(0); //初始化舵机角度Serial.begin(9600);}void loop(){while (Serial.available() > 0) {angle += char(Serial.read());delay(2);}if (angle.length() > 0){if (angle.toInt()<=360){myse.write(angle.toInt());}Serial.println(angle);angle = "";}}

然后UNO接上HC-05

接法：

STATE=NONE

RX=1

TX=0

GND=GND

+5V=5V

EN=3.3V
