Arduino Code:
char val; // Data received from the serial port
int ledPin = 2; // Set the pin to digital I/O 2
int ledPin2 = 4; //set the pin to digital I/O 4
void setup()
{
pinMode(ledPin, OUTPUT); // Set pin as OUTPUT
Serial.begin(9600); // Start serial communication at 9600 bps
}
void loop()
{
if (Serial.available())
{ // If data is available to read,
val = Serial.read(); // read it and store it in val
}
if (val == 'H')
{ // If H was received
digitalWrite(ledPin, HIGH); // turn LED1 on
}

else if (val == 'K') { //If K was recieved
digitalWrite(ledPin2, HIGH);//turn LED2 on
}
else if (val == 'P') {
digitalWrite(ledPin, HIGH); //If P was received
digitalWrite(ledPin2, HIGH);//turn both LEDs on
}
else if (val == 'L') {
digitalWrite(ledPin, LOW); // If is received
digitalWrite(ledPin2, LOW); //turn both LEDs off
}
delay(10); // Wait 10 milliseconds for next reading
