Each analog pin has a digital pin number assigned internally (for example, on Arduino Uno A0 = D14, A1 = D15, and so on). To use them as digital outputs, you simply use the same commands as with normal digital pins:

 
pinMode(A0, OUTPUT);
digitalWrite(A0, HIGH);
digitalWrite(A0, LOW);

Here, A0 is used directly, but you can also refer to it by its digital pin number (like 14 for A0). This allows you to extend the number of available digital I/O pins on your Arduino.

If yes, how to do this? I mean what command should I type?
