Reading a SHARP GP2D12/120 Infrared Ranger by BARRAGAN
Demonstrates how to connect and read values from a SHARP GP2D12 and GP2D120 family of infrared Ranger sensors. The ranger is connected to analog input pin 0. The value read from the sensor is proportional to the distance to an object or obstacle The value read is printed through the serial to be monitored using the serial monitor.

    int val;

    void setup()
    {
      Serial.begin(9600);      // sets the serial port to 9600
    }

    void loop()
    {
      val = analogRead(0);     // read analog input pin 0
      Serial.print(val, DEC);  // prints the value read
      Serial.print(" ");       // prints a space betwen the numbers
      delay(100);              // wait 100ms for next reading
    }
