00:00:07,000 --> 00:00:08,000
Hello, friends.

2
00:00:08,000 --> 00:00:16,000
In this particular part of video I just show you how to generate.

3
00:00:16,000 --> 00:00:22,000
In the previous video, we just go with how to generate multiple digital signals.

4
00:00:22,000 --> 00:00:31,000
But in this particular case, I go with how to acquire multiple digital signals using an eye tracker.

5
00:00:31,000 --> 00:00:34,000
First, I show you a simple case.

6
00:00:34,000 --> 00:00:38,000
Let's say I'm just using ground pin.

7
00:00:39,000 --> 00:00:44,000
So over here, this is my ground one and red one is my VCC.

8
00:00:45,000 --> 00:00:47,000
Or you can say five volt.

9
00:00:47,000 --> 00:00:52,000
As you see this one is ground and this one is five volt signal.

10
00:00:52,000 --> 00:00:55,000
So it is available over here.

11
00:00:55,000 --> 00:01:01,000
Now I just use different pins.

12
00:01:01,000 --> 00:01:08,000
Let's say I'm using 420 pin white one.

13
00:01:10,000 --> 00:01:12,000
Another one I have.

14
00:01:15,000 --> 00:01:17,000
Four zero pin number seven.

15
00:01:18,000 --> 00:01:19,000
Another one.

16
00:01:19,000 --> 00:01:22,000
1 or 0.

17
00:01:22,000 --> 00:01:23,000
Pin number two.

18
00:01:23,000 --> 00:01:30,000
So these are my different input supplies.

19
00:01:33,000 --> 00:01:35,000
I just connect one more LED.

20
00:01:38,000 --> 00:01:41,000
As you see or two over here.

21
00:01:41,000 --> 00:01:48,000
So let's say initially over here, this is my ground pin.

22
00:01:48,000 --> 00:01:54,000
So complete upper one layer up to here is my ground.

23
00:01:54,000 --> 00:01:57,000
And this one is my VCC.

24
00:01:57,000 --> 00:02:04,000
So now I just connect all the pins to the VC.

25
00:02:05,000 --> 00:02:05,000
VC.

26
00:02:06,000 --> 00:02:07,000
VC.

27
00:02:08,000 --> 00:02:10,000
And over here again VC.

28
00:02:10,000 --> 00:02:10,000
BC.

29
00:02:10,000 --> 00:02:16,000
So pin number I just used for two zero pin and four zero.

30
00:02:16,000 --> 00:02:18,000
Number seven and number two.

31
00:02:18,000 --> 00:02:25,000
So now I just go to the software part over here.

32
00:02:25,000 --> 00:02:29,000
I just need digital input.

33
00:02:30,000 --> 00:02:37,000
As you see over here you just need to select the pin numbers.

34
00:02:37,000 --> 00:02:48,000
So the pin number is line two, line seven and line 0 or 2.

35
00:02:48,000 --> 00:02:49,000
Apply it.

36
00:02:50,000 --> 00:02:54,000
Right now the data line will contain three signals.

37
00:02:54,000 --> 00:02:56,000
So you need to.

38
00:02:59,000 --> 00:03:02,000
Separate each value.

39
00:03:02,000 --> 00:03:04,000
So we need demux.

40
00:03:06,000 --> 00:03:08,000
Just connect this.

41
00:03:11,000 --> 00:03:16,000
And in the case of Demux you need to select number of outputs.

42
00:03:17,000 --> 00:03:18,000
Three.

43
00:03:19,000 --> 00:03:21,000
Display unit to display the value.

44
00:03:25,000 --> 00:03:28,000
As you see over here.

45
00:03:28,000 --> 00:03:31,000
It will show me the value.

46
00:03:36,000 --> 00:03:37,000
Second one.

47
00:03:38,000 --> 00:03:43,000
And over here we have third value.

48
00:03:43,000 --> 00:03:50,000
So now we just check the values.

49
00:03:50,000 --> 00:03:51,000
Just just run it.

50
00:03:52,000 --> 00:03:55,000
In this case it is showing one.

51
00:03:55,000 --> 00:04:04,000
As you see when I just change over here bc I just remove it.

52
00:04:04,000 --> 00:04:07,000
I just put ground over here right now.

53
00:04:07,000 --> 00:04:10,000
As you see, zero value is there.

54
00:04:10,000 --> 00:04:17,000
And when I just connect bc over here, it will show me one on all the trees.

55
00:04:17,000 --> 00:04:21,000
Now I just put again over here.

56
00:04:21,000 --> 00:04:28,000
This one is my BC and the purple one is my ground.

57
00:04:28,000 --> 00:04:31,000
Now I just want to change the values.

58
00:04:31,000 --> 00:04:33,000
Let's say over here.

59
00:04:33,000 --> 00:04:36,000
This one is ground again.

60
00:04:36,000 --> 00:04:38,000
This one is ground.

61
00:04:38,000 --> 00:04:43,000
So it will show me the value 100.

62
00:04:43,000 --> 00:04:52,000
So this is how you can acquire multiple digital signals with the help of National Instruments debt card.

63
00:04:53,000 --> 00:04:57,000
So this is all about today's lecture.

64
00:04:58,000 --> 00:04:59,000
Thank you.
