So right now, let us talk about the different Audrina we have, and we're going to start with the most
famous Arduino board, which is the Audrina Ono.
Now, this is how the owner looks like it has multiple inputs and outputs and it has some poorer section.
It has a lot of Io's on the right.
All of these are on the left, some of them are for power, some of them is for analogue, like the
S. And here it is divided between communication and digital.
All right.
So any of these digital io's can act as an input or an output, and it depends on how you can figure
it.
And you're doing a program.
So there's a configuration section where you decide if this is an input or an output.
Now, this section is for power, meaning if you want five volts or three point three volts, you can
get them from the expense.
Now, they cannot support a high, high current.
They can support only low currence, but at least you can activate some stuff from this to power supplies.
So if you power your adrenal from USPI, you would get a five point or three point three volts from
these two pins.
Now, this is zero to a five or actually your analog inputs.
So here is you, all of your analog inputs.
And they are all is where you take an analog signal and you sample it now from zero to 13 are digital
IO and they can be configured as input output.
And also the same Binz can be configured for multiple communication protocol.
Now we know the cereal.
The cereal is the tea and it has one transmitter and one receive, as you can see.
So these two are you A.R.T.?
There is other protocols that works differently and we did not talk about them yet, which are the eye
to see, which is right here.
These two boxes, these two lines.
And there is also the SBI, which is a very famous protocol as well.
And it has four wires, as you can see here.
And there is some inputs with interrupts, which we did not yet talk about.
But this is the main board.
This is how it looks like.
Now, let's see the specs of the original owner.
This is the clock speed.
Remember, we've talked in the EDL and veejays about clock and this is actually what the clock is.
The whole Adreno is running on 60 megahertz.
It means that it runs on sixty two point five nanoseconds waveform.
Right.
So if you have a way for in between every edge, there is sixty two point five nanoseconds.
Remember an hour the other when we get to simulation and we were creating that wave form of the clock.
This is the same concept and the clock period would be sixty two point five.
Now the operating voltage is five volts or all of those are either going to get five volts or output
five.
This is for digital, of course, now the power supply can be between seven and 12 volts, so you can
power your own Arduino between seven and 12 volts.
Now it has six analog pins.
So you have six bins that you can use for analog inputs.
You have 14 digital inputs and outputs, so you have 14 digital IO.
Now, every input or output can go up to 40 million members.
This is why when you connect different components, you need to consider that it cannot draw more than
14 million.
Otherwise, you would burn your Adreno.
Now we we have a couple of memories like Ethereum, like the flash memory here.
This is the flash where you put all of your code.
So you put a code and your code can be up to 32 kilobytes or a little bit less because there is some
boot code in order to make your Adreno up and running.
And it consumes around 12 kilobytes.
And then you have multiple Edstrom an EP of old memories that you use for your valuables, for your
four dynamic operations on your Adreno.
And they consist of around two kilobytes for RAM and one kilobyte for your own game.
So this is your program memory and this is your in operation, let's say memory.
OK, now let's jump to the Aldwin Omega.
The original Omega has a lot more inputs and outputs.
It runs on an analog of 60 megahertz as well.
Same as the you know, it has many more analog inputs.
It has many more B.W. outputs, which we will talk about later in the course.
And it has multiple items, seaports to see protocol.
So it's relatively larger board with.
So you can implement larger project because it has more Io's and more protocol bins attached to it.
So this is the specs it's operating on Five-fold the same as the know in between 712 volts.
Now it has 54 Iyo in compared to Ono, which has only 14 here and only had six analog inputs.
But here we have 16.
That's a huge number.
Now the flash memory is also larger.
There we had 32.
Here we have 256.
So we can write larger programs in the mega arduino.
And here before we had a sum of three kilobytes, but here we have a sum of 12 gigabytes for the dynamic
memory.
Next, the latest generation of what we know, which is the Beeley.
Thirty three, 33 cents.
This one has a lot of other stuff it has on board sensors, so it has a microphone.
It has a pressure sensor.
It also has some OCB LEDs.
It has accelerometers and gyroscopes on the board.
It are proximity light and go against your sensors.
It's really and a whole system on chipboard.
It also has Bluetooth attached to it.
So it is a really, really powerful Audrina where you can implement a lot of embedded projects because
you already have all of these sensors connected and all you need to do is just interface with them.
And you're doing a sketch.
Now, let's see the specs for that, it operates on three point three volt, not five volts.
So if you try to connect these inputs to the Adreno directly, well, you might damage your boat.
So you need to when you're interfacing this with five volt boards, you need to make sure that you are
stepping up your voltage or stepping down the other Borght voltage in order to meet the voltage requirement
in between two boats.
Now it can take 21 volt here.
Every oilcan has can draw 15 amps.
As you can see, the flash memory is really large.
It's bigger even than the mega.
It has one megabyte in mega we had 256 s ram is also large 256 for your dynamic memory.
That's really huge.
You have 14 eyeholes similar as the you know, all of you.
I always can be.
GWM That's great.
You have you want S.P., I want to see.
You have eight acres for input.
It does not have any AC, so you cannot really send voltage signals from this board.
It can have interruptible all points, which we will talk about this later.
And it has 13 built in ledes, and that's really great.
And by that, we have covered the most famous Aldwin Awards.
We will continue in the next lecture.
