终于搞定了Arduino和Flash的As3连接，真应该庆祝一下，呵呵。
下面程序实现的功能是点击flash上的按钮，arduino上就会开始闪灯，并接受arduino上发来的数据。再点击flash上的按钮，闪灯结束，并接受arduino上发来的数据。
——————————————————————————————————————————————
首先放上Arduino端代码：
#define LED_PIN 13
#define TOGGLE_LED_STATE 't' //定义一个来自Flash端的联系字符，随意定，与Flash端一样就可以
#define EOL_DELIMITER "$" //定义一个发送字符结束标记，也随意定
int incoming = 0; //定义一个变量，用于接收数据时用
boolean shouldBlinkLED = false; //是否闪灯值，初始为不闪
void setup()
{
Serial.begin(9600);
Serial.print("INITIALIZING"); //连接上电脑时发送一个字符串
Serial.print(EOL_DELIMITER);
pinMode(LED_PIN, OUTPUT);
blinkLED(5); //arduino刚连上电脑时闪灯5下
Serial.print("READY"); //发送“ready”到电脑端
Serial.print(EOL_DELIMITER);
}
void loop()
{
if(shouldBlinkLED) //如果闪灯，就闪灯一下
{
blinkLED(1);
}
if(Serial.available() > 0) //如果arduino接受到电脑端来的字符
{
incoming = Serial.read(); //变量incoming就等于受到的字符
if(incoming == TOGGLE_LED_STATE) //假如收到的字符与定义的字符相同
{
shouldBlinkLED = !shouldBlinkLED;//转变闪灯值，如果闪灯就变不闪，不然相反
Serial.print("LED BLINK STATE: "); //同时发送字符串"led blink state:"
if(shouldBlinkLED) //假如正在闪，发“on”
{
Serial.print("ON");
}
else
{
Serial.print("OFF"); //否则发"off"
}
Serial.print(EOL_DELIMITER);
}
}
}
//下面是闪灯程序，这就不解释了
void blinkLED(int count)
{ for(int i = 0; i < count; i++)
{
digitalWrite(LED_PIN, HIGH);
delay(500);
digitalWrite(LED_PIN, LOW);
delay(500);
}
}

下面是Flash端代码，建一个FlashBlink.as文件
