1. you should install arduino ide. Please refer to how to connect cubieboard and arduino

2. connect arduino and led as the Schematics

3. Use usb to connect arduino and cubieboard .

4. then we can start writing programs in arduino ide. we still make LED lights flashing, lit one second turns off one second

  int ledPin = 10;            //Defining Digital Interface 10
  void setup()
  {
  pinMode(ledPin, OUTPUT);    //Definition of small lights interface output interface
  }
  void loop()
  {
  digitalWrite(ledPin, HIGH); //Lit lamp
  delay(1000);                //Delay 1 second
  digitalWrite(ledPin, LOW);  //Extinguish  lamp
  delay(1000);                //Delay 1 second
  }
