Now, let us continue where we have left, we're going to introduce the transistor.
I'm not going to go deep in transistors at all right now, but I just want to tell you that this transistor
is the same as this, which we were studying.
And to sum it up really quickly, if you connect a battery at B, then C and we are going to act like
a closed switch.
If you remove the battery at B, well, then C and E are going to act as an open switch.
So you connect a battery C and they are connected with the battery and they are disconnected like an
open switch.
As simple as that.
No, I'm not going to go deep in this topology as well.
But when you connect transistors in a certain way, you're going to get gates, the same ones as we
have studied the and the old.
Now, this symbol right here is the oggi, so whenever you see the symbol, if you like, go deep inside
it, you're going to see something like that.
Electronics or transistors are connected with each other with this form right here.
Same thing at the end, whenever you see the symbol.
This is an end gate, which is the same as two switches in series together.
If you go inside it and take a look, you're going to get a topology that looks like this or similar
to this.
So this is a black box encapsulating this type of logic for the oil and here for the end.
Now we're going to build it up and see how this ends and all like for everything you know and everything
about embedded systems, because everything is going to start from this simple transistor and then combining
a bunch of transistors together to create gates like those and then multiple gates together are going
to form a different type of electronics component.
So see how the picture is getting bigger and bigger right now.
Now, in the next lecture, we're going to see how this picture is going to form our embedded systems.
