Hello, guys, and welcome back.
Now, since we are talking about adrenals, first thing we need to learn about this digital input's.
So digital input is really very simple.
Do you remember the switch in this small circuit that we have talked about?
Well, this is a digital input.
The switch itself is a digital input.
Now we have two type of digital input, either an input of zero or an input of one at zero or a low
one or high.
OK, so let's say that this is your Adreno and the we know has multiple digital inputs connected to
it.
So if you get the wire and you connect a switch right here and this switch is connected to some battery
to its high voltage like that.
So if you connect a five volt to this point now, if you close this, you will see the five volts coming
here.
And this five volt is nothing but a digital one.
So all of this one and zero are actually depending on the level of voltage.
So in this case, the high is five volt, meaning one means five volts and the original is going to
read a five volt right here.
Now, there is another type where you connect the switch to ground.
OK, if you can do that and you close the switch, a zero volt will be connected to this importunity
to this digital input and the Adreno is going to be creating a zero.
OK, so if you connect five volts, Aldwin will get one.
If you connect zero, Volt original agreed zero.
It is as simple as that.
This is the basics of digital inputs.
There is nothing much to it actually, other than what I am showing you right here.
