/*The Pololu GP2Y0A02YK0F is an analog distance sensor that uses infrared (IR) radiation to measure the distance of an object. Here's an example code in Arduino that reads the distance from the sensor:
Note: This code assumes that the Pololu GP2Y0A02YK0F sensor is connected to pin A0 of the Arduino board. If you're using a different pin, you'll need to modify the SENSOR_PIN definition accordingly. Also, the equation used to calculate the distance was determined experimentally, so you may need to adjust it for your specific sensor.

float voltage;  // the voltage reading from the sensor

  // read the voltage from the sensor
  voltage = analogRead(SENSOR_PIN) * (5.0 / 1023.0);

  // calculate the distance to the object in centimeters
  distance = 27.86 * pow(voltage, -1.15);
