Alcohol Sensor

int sensorValue;

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

void loop()
{
  sensorValue = analogRead(0);       // read analog input pin 0
  int level = map(sensorValue, 500, 780, 0, 10);
  if (level < 0)
      level = 0;
  if (level > 10)
      level = 10;
  Serial.println(level, DEC);  // prints the value read
  delay(100);                        // wait 100ms for next reading
}
