1
00:00:00,720 --> 00:00:07,550
Now let's start with our practical example for lead blank with arduino and lab view.

2
00:00:08,040 --> 00:00:15,540
In order to start with our example we need to love you to design our graphical user interface and set

3
00:00:15,630 --> 00:00:19,680
our control and serial communication frivolities.

4
00:00:19,950 --> 00:00:25,630
So follow my steps as we go in this lesson.

5
00:00:25,630 --> 00:00:31,100
And if you have any question regarding any of these steps you can ask in that you aren't able.

6
00:00:31,230 --> 00:00:34,050
I'll be happy to clarify everything for you.

7
00:00:36,690 --> 00:00:42,570
Now the first step is going to the start menu and search for love you

8
00:00:45,450 --> 00:00:55,360
as you can see and I love you 2019.

9
00:00:55,750 --> 00:01:01,280
As you can see I said I have 30 days remaining in my evaluation copy.

10
00:01:01,300 --> 00:01:02,800
So click evaluate

11
00:01:08,110 --> 00:01:10,180
now create a project

12
00:01:16,110 --> 00:01:25,010
as you can see it will show you some templates could create a blank project then click finish.

13
00:01:25,070 --> 00:01:25,860
Here we are.

14
00:01:26,800 --> 00:01:35,810
Now as you can see since this is a blank project you need to add a new V I find new VII.

15
00:01:35,890 --> 00:01:37,690
Now here is the front panel.

16
00:01:37,780 --> 00:01:40,510
And here is the block diagram panel.

17
00:01:40,540 --> 00:01:50,310
Now what you need to do is go to the block diagram which is the right window here and right click then

18
00:01:50,370 --> 00:02:01,950
select make out a hub from here go to the Linux or Linux library then choose option drag and drop open.

19
00:02:01,970 --> 00:02:15,120
Here now create a control by writing the first two wire steps as you can see here we have this is these

20
00:02:15,120 --> 00:02:15,990
two wild steps.

21
00:02:15,990 --> 00:02:23,510
The first five second one right click here with your mouse and create control.

22
00:02:23,510 --> 00:02:26,200
This is our first control element.

23
00:02:26,300 --> 00:02:36,980
Now you have to create a control for the second layer tip but we will leave this to the last step for

24
00:02:36,980 --> 00:02:37,540
now.

25
00:02:37,580 --> 00:02:43,280
Just create a control for the first way of tape which is serial port to choose the serial ball that

26
00:02:43,280 --> 00:02:46,560
you are connecting your Arduino to now.

27
00:02:46,610 --> 00:02:53,510
The next step will be after creating that control for the serial ball is going again to make our hub

28
00:02:54,410 --> 00:03:01,560
choose Linux and then drag the close as you can see this is our clothes.

29
00:03:01,580 --> 00:03:03,680
This will float the connection.

30
00:03:03,680 --> 00:03:09,790
Leave it here now right click again go to the make out hub Linux.

31
00:03:10,100 --> 00:03:19,210
And now when you go to work the professor allows you can select digital and write.

32
00:03:19,460 --> 00:03:21,800
This is that digital right.

33
00:03:22,010 --> 00:03:30,590
BLOCK And what you need to do now is create a control on second and third type of fire as you can see

34
00:03:30,590 --> 00:03:42,940
here we have this the all channel right click then create control and the third one is the output value

35
00:03:43,060 --> 00:03:53,400
right click Create control as you can see we have two controls for the second and third tab of the digital

36
00:03:53,440 --> 00:03:56,020
write function or block.

37
00:03:56,440 --> 00:04:05,580
Make sure that they are named the out channel or digital output channel and output value if their title

38
00:04:05,580 --> 00:04:07,170
is anything other than that.

39
00:04:07,200 --> 00:04:12,240
It means that you created control for wrong elements.

40
00:04:12,510 --> 00:04:19,800
Now that you have created control what you need to do is the following in the book the glamour world

41
00:04:19,800 --> 00:04:34,310
which is here right click then go to that structure menu after that go to the wire loop now drag and

42
00:04:34,310 --> 00:04:48,570
drop the wire loop in a way that you create that y loop and why loop is something that repeats what's

43
00:04:48,570 --> 00:04:56,410
inside it until this loop condition is correct.

44
00:04:56,420 --> 00:05:06,080
Now one thing that you need to do is take the serial configuration outside the loop and take the clause

45
00:05:06,170 --> 00:05:07,030
outside the loop.

46
00:05:09,090 --> 00:05:15,070
Now just keep that digitalized function inside the loop and let's make it smaller.

47
00:05:15,780 --> 00:05:18,620
We will talk about that in a minute.

48
00:05:18,760 --> 00:05:27,590
Now what you need to do next is right click on the why loop and click on Add shift just touch once you

49
00:05:27,590 --> 00:05:28,960
click adjust or just start.

50
00:05:29,060 --> 00:05:35,670
You will see two arrows here and you will use them and clarify why in a minute.

51
00:05:35,670 --> 00:05:42,300
Jeff there's just as you can see here we have two arrows for the shifter just now after creating the

52
00:05:42,300 --> 00:05:43,730
shift register.

53
00:05:44,150 --> 00:05:52,010
You need to go to the maker hub again right click here go to the make out hub and then go to the Linux

54
00:05:52,700 --> 00:05:54,560
utilities.

55
00:05:54,560 --> 00:06:06,920
And from here you can choose loop frequency or lubricate now drag this item and drop it inside the loop

56
00:06:09,230 --> 00:06:09,940
again.

57
00:06:10,130 --> 00:06:22,790
What you need to do is right clicking and select boolean and from boolean you need to choose this sine

58
00:06:25,960 --> 00:06:35,460
you need to choose this sign which is the off sign dragged on a little bit here inside the loop now

59
00:06:35,640 --> 00:06:43,800
again go right click here go to the timing and add weight in milliseconds inside the loop because we

60
00:06:43,800 --> 00:06:48,360
need this loop to let's say repeat itself.

61
00:06:48,360 --> 00:06:54,120
But with a delay so that we can monitor that changes that happens inside the loop.

62
00:06:54,120 --> 00:07:01,680
Now once you create that as you can see this is done inside the room and this is the way it function

63
00:07:01,830 --> 00:07:09,270
in milliseconds you need to create a stand for the weight right click here create kind of stand and

64
00:07:09,270 --> 00:07:17,560
here you can add anything I would add 1000 milliseconds which is basically one seconds.

65
00:07:17,610 --> 00:07:19,950
Now this is it.

66
00:07:19,950 --> 00:07:26,190
This is that these are the main components that we all need to add to the block diagram.

67
00:07:26,250 --> 00:07:29,700
Now what you need to do next is go to the front panel.

68
00:07:29,820 --> 00:07:30,900
Let me say this

69
00:07:36,030 --> 00:07:36,380
clay

70
00:07:39,530 --> 00:07:41,940
design.

71
00:07:42,080 --> 00:07:51,710
Let's go to the front panel here and in the front panel right click here choose boolean and then look

72
00:07:51,710 --> 00:07:54,830
for this top button.

73
00:07:54,830 --> 00:07:57,240
This is it.

74
00:07:57,370 --> 00:08:02,770
Now this to button if you double click on that button you will find it in this window as you can see.

75
00:08:03,130 --> 00:08:06,130
This is the button I double clicked here

76
00:08:09,450 --> 00:08:13,630
as you can see it is shown here.

77
00:08:13,660 --> 00:08:20,620
Now the stop button appears and the block diagram won't do what you need to do is drag and drop that's

78
00:08:20,620 --> 00:08:23,700
the button inside the loop

79
00:08:27,840 --> 00:08:29,650
now.

80
00:08:29,670 --> 00:08:34,180
Now follow my steps to connect all of these elements together.

81
00:08:34,410 --> 00:08:44,490
First what you need to do is assign a low blade for this element by going here right click here and

82
00:08:44,490 --> 00:08:48,290
create control OK.

83
00:08:48,330 --> 00:08:51,750
Let me show you this create an indicator here.

84
00:08:52,230 --> 00:08:56,550
This indicator will show us the frequency inherits.

85
00:08:56,550 --> 00:08:59,880
Now take this or item.

86
00:09:00,330 --> 00:09:09,320
Let's move these up here take this all item and that with the item will control our loop.

87
00:09:09,330 --> 00:09:11,920
So it will be responsible for stopping the loop.

88
00:09:12,840 --> 00:09:16,010
Let me maximize this.

89
00:09:16,030 --> 00:09:20,830
OK now delay element should be life here.

90
00:09:20,890 --> 00:09:22,670
We won't do anything with it.

91
00:09:22,690 --> 00:09:28,090
Now we have these elements we need to connect the Linux items together.

92
00:09:28,090 --> 00:09:38,550
What we need to do first is connect the next source from this open function to this Linux source.

93
00:09:38,920 --> 00:09:43,360
And the out of this must be connected to the close.

94
00:09:43,400 --> 00:09:48,650
This is the first step the second step is connecting that error out.

95
00:09:48,830 --> 00:09:53,640
Now the error must be connected through the shift register

96
00:09:56,440 --> 00:09:57,520
as you can see it again.

97
00:09:57,580 --> 00:10:04,780
And we will take that out from here and connect it to the end and the closed function in case of an

98
00:10:04,840 --> 00:10:05,310
error.

99
00:10:05,680 --> 00:10:08,150
Well I think wrong happened.

100
00:10:08,500 --> 00:10:14,850
Now we have our good value is that output channel and loop rate.

101
00:10:15,040 --> 00:10:23,130
We will take the arrow from here and give it to the order function and we will take the stop button

102
00:10:23,280 --> 00:10:24,570
and give it to the order function.

103
00:10:24,570 --> 00:10:32,910
Now if there were or if an error occurred or if we clicked on the stop function both of these or any

104
00:10:32,910 --> 00:10:39,080
of these two will stop the loop and will stop our program which is basically what we want.

105
00:10:39,120 --> 00:10:44,280
This is the main purpose of the error signal from the Linux library.

106
00:10:44,490 --> 00:10:51,900
If there is an error or if we stop thus or free click the stop button it must stop the loop using this

107
00:10:51,900 --> 00:10:55,260
top condition function.

108
00:10:55,260 --> 00:10:58,410
Now we have everything up and ready.

109
00:10:58,410 --> 00:11:03,780
And if you connected everything like that you should have your software ready.

110
00:11:03,900 --> 00:11:14,680
Now what you need to do next is go and let's say out of Angel visual interface.

111
00:11:14,800 --> 00:11:17,590
This is an indicator for the output value

112
00:11:21,610 --> 00:11:26,280
between the dog rocketeers and lets that all period

113
00:11:29,650 --> 00:11:36,090
let's maximize this stop button like that.

114
00:11:36,500 --> 00:11:38,920
That there's that output channel.

115
00:11:39,110 --> 00:11:45,090
Here we can select are doing the channel that we want to use.

116
00:11:45,210 --> 00:11:49,320
And here is our output value for it.

117
00:11:49,350 --> 00:11:54,590
Now we have our program a bunch of data to save everything save on

118
00:11:57,260 --> 00:11:57,790
design.

119
00:11:58,980 --> 00:11:59,940
OK.

120
00:12:00,050 --> 00:12:04,190
Now that we saved everything let's check that

121
00:12:07,540 --> 00:12:11,930
as you can see that shift I just thought is on wild.

122
00:12:11,960 --> 00:12:12,310
OK.

123
00:12:12,320 --> 00:12:16,850
We did forgot to connect this through the channel.

124
00:12:17,300 --> 00:12:27,300
That's if they're just so disconnected.

125
00:12:27,570 --> 00:12:28,360
That's it.

126
00:12:28,380 --> 00:12:38,130
Now there is no errors as you can see but since we don't have an albino connected we will get an error

127
00:12:38,130 --> 00:12:40,000
when we are running the software.

128
00:12:40,080 --> 00:12:42,080
Now our software is up and ready.

129
00:12:42,210 --> 00:12:44,540
What you need to do is save all.

130
00:12:44,580 --> 00:12:50,190
And then next us on we'll explain how you can fund the Linux firmware was it.

131
00:12:50,250 --> 00:12:51,390
Thanks for watching this on.

132
00:12:51,390 --> 00:12:53,670
This is Asha from educational engineering team.
