Let's us know an LCD screen to our secret.
So the screen will be super useful so we can display some text directly from the Arduino, so density
we are going to use a 16 by two.
OK, and well, I'm going to put it there on tin can.
And then you will see that I'm going to directly plug it here on the bread board when I do the real
secret.
But for the just for the simulation and to show you the connections for the beans, there's going to
be easier like this funnel.
So you have many connectors here and let's go step by step one by one.
First, you have a GNT, so ground you're going to connect to the ground line.
Let's make sure that is ground light.
OK.
It's actually pretty, ladies.
So ground is going to be black and then you have this ESI and this is you connect to.
The this is your line here.
Five volt line, then we have V0, V0 is going to be used to calibrate the luminosity of the screen,
OK, using a potential meter.
So basically here we need to also add a potent emitter.
So I'm going to put it put on soumettre here.
And so the potential, do you have three legs?
You want to put one of the leg, for example, the left one connected to the ground.
Blackwell and then the opposite one connected to.
My vote.
We've all read the wire and then you're going to connect this V0 here.
To the middle pin of the potential middle.
And but it OK.
The next thing is the art has been and, well, this one, you're going to plug it in to a digital pin.
But because we will not have enough digital print, I'm going to plug it into an analog pin instead.
So I'm going to plug it to a phone because, well, you can use actually analog pins as digital pins.
So if you ever run out of digital pins, just use an analog instead and into just use it as a digital
pin, and it's changed color green and then R.W other where he was going to be connected to the ground
with a black wire and for enable.
He is going to a five the same reason as for a spin.
Let's use a different color, for example, purple.
We're going to use this as a digital pin because we won't have enough digital pins here on the secret
for all the components.
Then you have the zero, one, two and three.
You're not going to put anything for those things here.
And then before default, we're going to plug it to the digital pin number two.
So let's use another color for the yellow.
OK, DeFi is the next one two digital pin number three.
Let's use.
Grass and then six to digital in full, so we just follow, we think, the seven to.
Digital been five, all right.
Use a range.
OK.
And then we have energy, so we have to.
The first one is going to be connected to five volt, but with a variety store.
So that's going to be the energy of the LCD screen.
OK.
Because when you use actually and it is here, you can see we use arises also.
That's the same reason here.
I'm going to add every store here to 120 on, and I'm just going to connect it between.
Yet this reaction on the LCD, we read wire and then connected to the.
He line the five volt line, and then we have that one connected to the ground.
All right.
One thing to make sure that you don't do is so don't connect anything to those beings here.
Digital been zero and one.
Why is that?
You can see we have Alex and Tina.
So those pins are also actually used for cellular communication.
So when later on, we use cell communication with the USB cable?
If you have anything plugged here, you're going to have some weird behavior.
OK, so you're going to have some arrows on the same communication and maybe also on the components
that you use on those pins to leave those pins and.
And here is the secret with the LCD screen, so this can look a bit messy, but well, actually, if
you just follow all the steps that I did on Tinker, you should not have any problem.
So I have blinked as you see the screen directly on one of the line here.
So each should each pin each leg of the LCD on a different line.
OK?
This is not connected on the blue.
All of the red line.
This is connected here.
Separated lines on the right book and then you can see each connection here.
So I have the first one.
Maybe you will have lots of different names.
OK, on the on the LCD.
So you have, for example, as we did at the end, I have eight and Kate.
So the name can be different, but the other is going to be the same as what I did before.
So the first one is connected to the ground here.
The second one she does right away is connected to this, you see.
And then the third one is V0.
So v0 is he connected?
So this blue connected to the output been off the potential meter and the potential meter also has.
So for the two extreme legs, a black way out to the ground and the right wire to this issue.
After that, we have the.
R s R s, which is going to take you to a fall and then we have the RW RW connected to the ground here
with this black wire, the E for Enable connected to A5.
And then we have nothing for zero until three.
And then you can see D4 device connected to digital pin number two and then D5 to digital P three.
The six two digital twin full and the seven two digital pin number five.
At the end, we have so for the A here, which is basically the positive side of the energy of the screen.
I have one 220 Ohm Restall connected from here to a different line, and then this red wire connected
to the plus lanky and the bright block and the last connection here is a black way up to the ground.
All right.
And that's it for the LCD screen.
