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 = "";

}

}

}
