基于android和arduino 的小车控制

 基于android和arduino 的小车控制，小车部分采用的是 arduino 开源硬件实现，arduino 学起来比较简单，看看文档在看几个例子基本就会了。官网是http://arduino.cc/

我是在某宝上购买的一组套件，最终发现很多都没有用上，有点眼高手低。android 和 arduino 通信 是通过蓝牙。小车控制比较简单，前、后、左、右、向左转圈、向右转圈。

以下是源码；

1：arduino 源码：

 

 

#include

    Serial.begin(SERIAL_SPEED);
  }
}

void loop() {
  // RECEIVE_VALUE=Serial.read();
  //Serial.println(RECEIVE_VALUE);
