const unsigned char LED = 13;
byte comData;    //定義從串口接收過來的數(shù)據(jù)

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);    //初始化串口，波特率設(shè)置為9600
  pinMode(LED, OUTPUT);    //設(shè)置數(shù)字引腳為輸出模式
}

void loop() {
  // put your main code here, to run repeatedly:
  if (Serial.available() > 0) //檢測串口緩沖區(qū)是否有數(shù)據(jù)
  {
comData = Serial.read();
if (comData == 0x01)       //接收到該命令，則執(zhí)行關(guān)燈
{
   digitalWrite(LED, LOW);
}
if (comData == 0x02)       //接收到該命令，則執(zhí)行開燈
{
   digitalWrite(LED, HIGH);
}
  }
