Serial to Arduino Pins Test

/* Controlling pins on an Arduino port via Serial */

byte incomingByte = 0; // variable for incoming serial data

void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
DDRB= B00111111; //Set Port B as output (Pins 8 to 13)
/* it's an 8 Bit port but two highest pins
   are used by crystal and not accessible */
}

void loop() {

// Listen for incoming Serial data:
if (Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read(); //Read from Serial Port
PORTB=incomingByte; //output data to Port B

/* so, if you send 8 to serial,Port B will become 00010000
send 3 Port B will become 00000011
send 2 Port B will become 00000010
send 6 Port B will become 00000110
send 255 Port B will become (11)111111
and so on

NB this is assuming P.D sends data as actual numbers (Bytes) and not ASCII data.
if it doesn't there is a workaround.
