Good Morning! Thank you very much for your response. I pasted the codes below. My idea of making two buttons for each Arduino pin so that clicking one button will make the pin HIGH and the clicking other will make that pin LOW. Command I meant clicking the buttons from Processing Software. I don't have any problem making only one Arduino pin HIGH/LOW from Processing Software. Now I want two pins to be HIGH/LOW independently. If you think it can be done in simpler way, please let me know. I would appreciate very much.

char val2; // variable to receive data from the serail port 2
int ledpin = 9; // Arduino LED pin 9
int pin = 11; // Arduino LED pin 11
// software serial #1: RX = digital pin 0, TX = digital pin 1
SoftwareSerial portOne(0, 1);
// software serial #2: RX = digital pin 2, TX = digital pin 3
SoftwareSerial portTwo(2, 3);
void setup() {
pinMode(ledpin, OUTPUT); // pin 9 (on-board LED) as OUTPUT
pinMode(pin, OUTPUT);
Serial.begin(9600); // start serial communication at 9600bps
portOne.begin(9600);
portTwo.begin(9600);
}
void loop() {
portOne.listen();
if( portOne.available() ) // if data is available to read
{
val1 = Serial.read(); // read it and store it in 'val1'
}
if( val1 == 'H' ) // if 'H' was received
{
digitalWrite(ledpin, LOW); // turn ON the pin 9
}
else
{
digitalWrite(ledpin, HIGH); // otherwise turn it OFF
