Hello, friends.
In this particular part of video I just show you how to generate.
In the previous video, we just go with how to generate multiple digital signals.
But in this particular case, I go with how to acquire multiple digital signals using an eye tracker.
First, I show you a simple case.
Let's say I'm just using ground pin.
So over here, this is my ground one and red one is my VCC.
Or you can say five volt.
As you see this one is ground and this one is five volt signal.
So it is available over here.
Now I just use different pins.
Let's say I'm using 420 pin white one.
Another one I have.
Four zero pin number seven.
Another one.
1 or 0.
Pin number two.
So these are my different input supplies.
I just connect one more LED.
As you see or two over here.
So let's say initially over here, this is my ground pin.
So complete upper one layer up to here is my ground.
And this one is my VCC.
So now I just connect all the pins to the VC.
VC.
And over here again VC.
BC.
So pin number I just used for two zero pin and four zero.
Number seven and number two.
So now I just go to the software part over here.
I just need digital input.
As you see over here you just need to select the pin numbers.
So the pin number is line two, line seven and line 0 or 2.
Apply it.
Right now the data line will contain three signals.
So you need to.
Separate each value.
So we need demux.
Just connect this.
And in the case of Demux you need to select number of outputs.
Three.
Display unit to display the value.
As you see over here.
It will show me the value.
Second one.
And over here we have third value.
So now we just check the values.
Just just run it.
In this case it is showing one.
As you see when I just change over here bc I just remove it.
I just put ground over here right now.
As you see, zero value is there.
And when I just connect bc over here, it will show me one on all the trees.
Now I just put again over here.
This one is my BC and the purple one is my ground.
Now I just want to change the values.
Let's say over here.
This one is ground again.
This one is ground.
So it will show me the value 100.
So this is how you can acquire multiple digital signals with the help of National Instruments debt card.
So this is all about today's lecture.
Thank you.
