The Motor sample to link wries 
¾  Serial Port   
This example shows you how to monitor the state of a switch by establishing serial communication 
between your Arduino and your computer over USB. 
Sample code 
/* 
      DigitalReadSerial . Reads a digital input on pin 0, prints the result to the serial monitor   
    Use the example of gp2y0A21.to see how the Serial work. 
 */ 
const int GP2Y0A21 = 0;      //set analog pin 0 as the signal pin 
int incomingByte = 0;      // for incoming serial data 
void setup() 
{ 
    Serial.begin(9600); // opens serial port, sets data rate to 9600 bps 
}
