Sample Code:

• String comdata = "";
  Void setup ()
  {
  PinMode (2, the OUTPUT);
  PinMode (3, the OUTPUT);
  DigitalWrite (2, HIGH);
  DigitalWrite (3, HIGH);
  Serial. The begin (9600);
  }
  
  Void loop ()
  {
  
  DigitalWrite (2, HIGH);
  DigitalWrite (3, HIGH);
  While (Serial. The available () > 0)
  {
  Comdata + = char (Serial. The read ());
  Delay (2);
  }
  If (comdata. Length () > 0 && comdata = = "0500 addf1443")
  {
  While (comdata. Length () > 0)
  {
  DigitalWrite (3, LOW);
  Delay (100);
  While (Serial. The available () > 0)
  {
  Comdata + = char (Serial. The read ());
  Delay (2);
  }
  Comdata = "";
  }
  }
  Else if (comdata length () > 0)
  {
  While (comdata. Length () > 0)
  {
  DigitalWrite (2, LOW);
  Delay (100);
  While (Serial. The available () > 0)
  {
  Comdata + = char (Serial. The read ());
  Delay (2);
  }
  
  Comdata = "";
  }
  }
  }
