===== Make LED Lights flashing =====
{{:tutorials:arduino:image.jpeg|400}}
===== Schematics =====
{{:tutorials:arduino:xlzomm.jpg?500|}}

===== Steps =====

1. you should install arduino ide. Please refer to 
[[http://docs.cubieboard.org/tutorials/arduino/connecting|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
=====Source Code=====

    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
    }
