  29. /* A stepper motor drives a 200 mm length linear rail */
  30. /* slide. The motor performs 100 steps per */
  31. /* revolution. Each revolution moves the slide 10mm. */
  32. /*
  33.    Here, we assume that the stepper motor is properly configured
  34.    to achieve this requirement. Hence, no changes are required in the code.

  37. /****** SYSTEM REQUIREMENT 2 *****/
  38. /* Perform a complete continuous travel from right to */
  39. /* left in 12 hours. Then go back from left to right */
  40. /* again in 12 hours. The movement shall be */
  41. /* continuous in 12 hours. Do not use delay function. */
  42. /*
  43.    In order to achieve this requirement, we need to modify
  44.    the loop function to continuously run the stepper motor
  45.    for 12 hours in one direction, then reverse the direction
  46.    and run for another 12 hours. We can use millis() function
  47.    to track the time and control the motor movement.
