I figure now there is an audit order and what type of what it is are in.
You know, they're the most sorted boat out here.
Let me zoom in so that I can show you every single thing into this in a very clear order.
And, you know, what are the things you have into this audit board?
And then we'll begin with it.
So let's start from the.
So if we just have a look at this audit of what we have here and you can see this, it looks almost
the same out there, right, what we have out here.
So if I could show you here, it just looks the same thing.
So starting from here, so onto this side, you have a digital pens.
And we have understood very well, like in earlier sessions, like what is a digital and what is an
analog of that.
So these elements are nothing but a discrete pens, which is going to give you the one or zero.
So how many of you have it starting from the zero until 13, you have almost zero plus 13 pens, right?
Which are digital pens.
And then you have one pen as a crown and one for a reference.
And then you have a some symbols you can see here, if you just see the symbols and the symbol, the
symbol and the symbol.
And here also you have a few points.
So this means that these pens can support p w m what is the p m pulse modulation.
More about that later.
Then at the last three you also have something called TCS and RECs for zero and one.
So what is x to T?
X is a transmission or X's receiver Receiver.
So the transmitter and the receiver, the X is the transmitter or the receiver.
The reason why we have this is because we do not have any sort of connectivity, wireless connectivity
with this, just in case.
Imagine that you have to go ahead and make use of a Bluetooth module, which you want to connect with
this, which also we'll be doing in the sessions.
So if you want to do this, then how do you connect it together?
So how do you get that?
So you're going to make use of this or anti X so that you can get started with them?
Okay.
More about that later.
So once we are done with it.
Then we have this particular lady out here.
It is saying, Oh, so this is going to give you a indicator indication like whether the ordinance is
turned on.
It has a power supply or not.
So based on that, we have a power supply and not we get to have it here.
All right.
Then we have or if the power supply is available, this will glow in green color.
And if not, No.
And just in case, if you have done any short circuiting anywhere here, anybody have done some short
circuiting, this may turn out.
So you may easily get to know there is some issue with the connections of that.
Then we have a L, which is, again, one more area out here which indicates which is better a lady
out there.
So by default, there is one levee which is built into the ordinance itself for programming.
So we can program this levee internally, very importantly, internally.
This is also connected to PIN number 13.
So if you make a PIN number 13 high, which in turn means that this will turn on.
If you make PIN number 13 low, this will turn off because this is connected to this.
All right.
So there is a built in lady.
There will be seeing that in sometime.
Then we have a scenario.
So what is it again?
Transmitter and receiver.
So whenever there is a transmission of a civil a receiving happening, the sticks and arcs will blend.
All right.
I'll share that also.
And some time.
Let us go ahead here and see what other different things we have into it, which we will not be using
it because you will not be going through and doing any sort of manipulation to this.
We are going to only use these pins and the pins on the other side.
But I'm just going to tell you everything on that so that you're very confident what exactly you have
in your development board.
So here you have a you are this is a digital converter which is going to convert this particular USB
to this will help the data from coming from here to this particular microcontroller.
All right.
TTL converter.
Transistor.
Then we have a 3.3 voltage regulator.
This is a 3.3 voltage regulator which will go ahead and step down the five volts which is coming from
this micro micro-usb to 3.3 volts because this ice is going to work on 3.3 volts only.
And then we have this is an oscillator which is of 16 megahertz frequency.
It is the clock actually, which is 16 megahertz.
These two are our 24 volts capacitor, hopefully no 25 volts capacitor.
So there's not a 25 volts capacitor.
And this is a DC jack.
You can see this here.
This is a DC Jack.
What you have here where you can go ahead and give up to 25 volts of power supply.
And this capacitors will handle that voltage.
Regulators will handle that, and that should work perfectly fine, but nobody uses this.
Actually, that doesn't really make a sense.
The other side of the other side of the board here you have analog pens.
Now, analog pens are nothing, but we can take analog data signal and also give you an analog data
signal output.
So how many options we have is zero to a five of $0.06 you have into it.
Then we have some power we in that if you want to give a five and then again give from this then to
ground pens, you have it.
Then again, five words output, you have it.
So this will give you five volts output.
Then three was 3.3 was output.
It is doing this in an eye reference pen.
So these are the different paints that we have into this particular and this is your main microcontroller
which is of $0.28 14 on each side.
So this is a mega 328 B microcontroller.
So they're going to help us do all the things we would go ahead and need to do with this.
So let us go ahead and then have a look at what are the different things we have and.
See what can we do with this?
So.
This update three $0.28 what we have as a sample out here.
It has a 16 megahertz.
Clock frequency of their.
So it is a 16 megahertz clock frequency of that and it just have a 32 kilobytes of system programmable
memory, 32 kilobytes and one kilobytes of e rom and two kilobytes of s ram that is ram of that.
So very simple.
And all these are eight channels ABC that is eight.
So and this microcontroller, what you see is also an eight bit microcontroller.
It can process only eight weeks at a time.
I think.
So the computer's what we have at this are 64 bit microcontroller, 64 bit microprocessors, but this
is eight bit microcontroller.
And when I say it with microcontroller and when I say 64 bit microprocessor, you might be like, this
is very low in number, right?
What can this literally do?
Trust me, it can do amazing things which you cannot even think of.
Eight bits can do a lot much.
So this is all about what is this particular thing, what you're going to use now?
And let's get going with this and start with it.
