Code

Main Code

Arduino
Arduino code for loading the project
#include <Stepper.h> 
#include <Tle493d_w2b6.h>

// change this to the number of steps on your motor
#define STEPS 800

// create an instance of the stepper class, specifying
// the number of steps of the motor and the pins it's
// attached to

Stepper stepper(STEPS, 4,5,6,8);


/**
* This example demonstrates the use of low poewr mode of sensor TLE493d-W2B6
*/

double rotationPos = 0;

Tle493d_w2b6 Tle493dMagnetic3DSensor = Tle493d_w2b6(Tle493d::MASTERCONTROLLEDMODE);
void setup() {

  // set the speed of the motor to 30 RPMs
  stepper.setSpeed(10);
  
  Serial.begin(9600);
  while (!Serial);
  Tle493dMagnetic3DSensor.begin();
  // The highest adjustable range is used for all three directions, i.e., within half of the total value range INT is disabled 
  // this has no effect on the TLE493d-A2B6 sensor
  Tle493dMagnetic3DSensor.setWakeUpThreshold(1,-1,1,-1,1,-1);

  //The update rate is set to 3 (fastest is 0 and slowest is 7)
  Tle493dMagnetic3DSensor.setUpdateRate(3);

  
}

void loop() {
  Tle493dMagnetic3DSensor.updateData();
  // rotationPos is getting the polar degree that the dial is turned
  // I converted radians to degrees to be easier to read
  rotationPos = Tle493dMagnetic3DSensor.getAzimuth()*57.3 + 180;
  // Serial print it so that I can see that the system is working
  // correctly
  Serial.println(rotationPos);

  // If I turn it to the right it'll be around 90 degrees but I 
  // put in a tolerance of 45 degrees
  if (rotationPos > 45 && rotationPos < 135) {
    Serial.println("To The Right");
    stepper.step(200);
  }
  // I did the same tolerance for turning left
  else if (rotationPos > 225 && rotationPos < 315) {
    Serial.println("To The Left");
    stepper.step(-200);
  }

  delay(50);
}

Stepper Motor Test

Arduino
This is to verify your wiring for the stepper motor portion
#include <Stepper.h>

// change this to the number of steps on your motor
#define STEPS 400

// create an instance of the stepper class, specifying
// the number of steps of the motor and the pins it's
// attached to
Stepper stepper(STEPS, 4, 5, 6, 8);


void setup()
{
  Serial.begin(9600);
  Serial.println("Stepper test!");
  // set the speed of the motor to 30 RPMs
  stepper.setSpeed(60);
}

void loop()
{
  Serial.println("Forward");
  stepper.step(STEPS);
}
