Спасибо, добрый вечер. Посмотрю, нельзя целиком код прислать?. Мой код #include <QTRSensors.h>
// This example is designed for use with six QTR-1A sensors or the first six sensors of a
// QTR-8A module. These reflectance sensors should be connected to analog inputs 0 to 5.
// The emitter control pin can optionally be connected to digital pin 2, or you can leave
// it disconnected and change the EMITTER_PIN #define below from 2 to QTR_NO_EMITTER_PIN.
// The setup phase of this example calibrates the sensor for ten seconds and turns on
// the pin 13 LED while calibration is going on. During this phase, you should expose each
// reflectance sensor ot the lightest and darkest readings they will encounter. For
// example, if you are making a line follower, you should slide the sensors across the
// line during the calibration phase so that each sensor can get a reading of how dark the
// line is and how light the ground is. Improper calibration will result in poor readings.
// If you want to skip the calibration phase, you can get the raw sensor readings
// (analog voltage readings from 0 to 1023) by calling qtra.read(sensorValues) instead of
// qtra.readLine(sensorValues).
// The main loop of the example reads the calibrated sensor values and uses them to
// estimate the position of a line. You can test this by taping a piece of 3/4" black
// electrical tape to a piece of white paper and sliding the sensor across it. It
// prints the sensor values to the serial monitor as numbers from 0 (maximum reflectance)
// to 9 (minimum reflectance) followed by the estimated location of the line as a number
// from 0 to 5000. 1000 means the line is directly under sensor 1, 2000 means directly
// under sensor 2, etc. 0 means the line is directly under sensor 0 or was last seen by
// sensor 0 before being lost. 5000 means the line is directly under sensor 5 or was
// last seen by sensor 5 before being lost.
#define NUM_SENSORS 6 // number of sensors used
#define NUM_SAMPLES_PER_SENSOR 4 // average 4 analog samples per sensor reading
#define EMITTER_PIN 2 // emitter is controlled by digital pin 2
// sensors 0 through 5 are connected to analog inputs 0 through 5, respectively

// from 0 to 5000, where 0 means directly under sensor 0 or the line was lost
// past sensor 0, 1000 means directly under sensor 1, 200 means directly under sensor 2, etc.
// Note: the values returned will be incorrect if the sensors have not been properly
// calibrated during the calibration phase. To get raw sensor values, call:
// qtra.read(sensorValues);
unsigned int position = qtra.readLine(sensorValues);
