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 = "";
}
}
}
