// Configuration values:
#define SERIES_RESISTOR 750 // Value of the series resistor in ohms.
#define SENSOR_PIN 0 // Analog pin which is connected to the sensor.
// The following are calibration values you can fill in to compute the volume of measured liquid.
// To find these values first start with no liquid present and record the resistance as the
// ZERO_VOLUME_RESISTANCE value. Next fill the container with a known volume of liquid and record
// the sensor resistance (in ohms) as the CALIBRATION_RESISTANCE value, and the volume (which you've
// measured ahead of time) as CALIBRATION_VOLUME.
#define ZERO_VOLUME_RESISTANCE 0.00 // Resistance value (in ohms) when no liquid is present.
#define CALIBRATION_RESISTANCE 0.00 // Resistance value (in ohms) when liquid is at max line.
#define CALIBRATION_VOLUME 0.00 // Volume (in any units) when liquid is at max line.
