MECH 430 Midterm, Spring 2012

Lab HW 6 Create a VI that has the front panel shown below. The user fills in manually the numbers in Array 1 and in Array 2. These should be integers between 1 and 20 inclusive (5 integers in each array). After that, the user should run the VI, and nothing should happen when that Run button is pressed. Then the user should press the FILL button shown on the front panel. When the user presses FILL, LabVIEW should fill in Array 3 by 5 random integers between 1 and 20 inclusive. This filling should be done in order at a rate of 1 number each half a second. For example, in the front panel shown below, Array 3 should show the numbers 0, 0, 0, 0, 0 when the user presses FILL; after half a second 10, 0, 0, 0, 0; after a second 10, 3, 0, 0, 0; after a second and a half 10, 3, 14, 0, 0… and so on. After filling of Array 3 is completed, the LED named ‘Analyzing Results’ must flash ON and OFF at a rate of 1 flash every 0.6 seconds (meaning 0.6 seconds ON, 0.6 seconds OFF). This flashing should go on for 6 seconds (a total of 5 ON’s and 5 OFF’s). After these 6 seconds, LabVIEW should display in a string indicator named ‘Unacceptable Numbers’, the Unacceptable Numbers. A number is considered Unacceptable if:  The number is in Array 3.  There is an equal number to it in Array 1 or in Array 2.  The number equal to it in Array 1 or in Array 2 is the same index as the tested number. For example (in the figure below) the number ‘3’ in Array 3 has an equal to it in Array 2 at the same position, and therefore, number 3 in Array 3 is considered Unacceptable. The String indicator should display the Unacceptable number, the index number of the similar to it, and in which array is the similar number found (see figure below..). If there is no Unacceptable numbers, the String indicator should display “All the numbers are acceptable”. If Unacceptable numbers do appear, then we will consider that LabVIEW has failed to fill Array 3 with appropriate numbers, and therefore, we will try again. So, each time LabVIEW fails to fill Array 3, the user may press FILL again and the same procedure described in part A should be repeated.. Until there are no Unacceptable numbers at which LabVIEW stops execution. No local variables are allowed.
