Good morning, you have already registered in the www.tinkercad.com webpage, so you will be able to log in and you will be able to see something like that. 00:00:00
Ok, in Tinkercad.com there are different possibilities, we can create 3D designs, but now we are going to create circuits. 00:00:14
So we click on this label, circuits, and now, I have already done a lot of designs, but you will have no one. 00:00:21
So, anyway, you have to click on Crear nuevo circuito, create new circuit. 00:00:29
Click on it and the screen will change. 00:00:34
Something like that will appear, ok? 00:00:38
Something like this, I mean. 00:00:40
Here, on the right, you have the library of components. 00:00:42
We will click and drag them to use them. 00:00:45
Well, the first thing we need, well, for this exercise the basic library is enough. 00:00:47
So we will move a little bit down and now we have the protoboard. 00:00:52
a protoboard. Click and drag and now we will have the protoboard. The protoboard is a way 00:00:56
to connect things. We will study it in one minute. The next component we need is the 00:01:01
Arduino board, so we click it here. We will also need an LED. An LED is a tiny bulb, a 00:01:07
really small one. And we will also need a resistor. The first thing we have already 00:01:15
clicking and dragging and we click and drag and we have everything we need on 00:01:23
the screen. The first thing we need is change the value of the 00:01:27
resistance. This one by default is one kilo ohms, one. So but we need 220 ohms so 00:01:33
we change the number 220 ohms and we are sure that instead of having kilo ohms we 00:01:41
have ohms. So now we have the resistor we want. The resistor has to be connected to 00:01:46
Because the Arduino board will provide a lot of energy and the LED doesn't support all the energy that will be provided. 00:01:51
So the resistor will take part of the energy and that's why it's called protection resistor. 00:02:01
Now the resistor is connected to the LED. Why is it connected? 00:02:08
Because can you see that there are five green slots? Yes, there are five. 00:02:11
five, and it means that these five slots are connected. Everything that is 00:02:16
connected to one of these five slots is connected because there is a kind 00:02:20
of metal stripe under the plastic. Every five green slots 00:02:25
are connected here, here, here, here, but all of them are vertical as you can 00:02:31
see, but there are four long horizontal resistors, stripes, lines I mean. 00:02:37
This one, this one, this one and this one, but the rest of them are vertical. 00:02:43
So now the resistor and the LED are connected, are connected through these five vertical 00:02:48
slots. 00:02:55
Okay. 00:02:56
Another thing we want is connecting the Arduino board to the LED. 00:02:57
So we are going to connect using wires. 00:03:04
To use wires is really really easy. 00:03:06
Using wires is really really easy. 00:03:08
The only thing you need to do is click in here, for instance, and we are going to connect it to the ground, tierra. 00:03:09
Ground, well, first of all, the color of the wire will be black. 00:03:15
Why? Just because. 00:03:20
Well, because it's the usual color for the ground connection. 00:03:21
Ground connection, in this context, means the negative terminal of a battery. 00:03:25
The Arduino board will work as a battery, a battery that can be programmed, 00:03:29
that we will change its behavior according to the thing we want. 00:03:34
but it's a kind of battery. So the ground now is connected to 00:03:38
the straight part of the LED 00:03:42
and you see that there are two parts. This one is straight, the other one is not. The straight part is 00:03:46
called cathode in English and this is the one that is not straight. 00:03:50
Usually, always, the wire connected to ground 00:03:55
the one that usually is black has to be connected here. And the one 00:03:58
the other one will be connected to connector number 00:04:02
13. Why 13? Just because we want to. We can use for instance red, I don't know, just because. 00:04:06
So now we have a closed circuit. This is the negative terminal and the negative terminal 00:04:15
is connected to the LED and to the resistors using these two green, five green slots. Okay, 00:04:21
so we have a closed circuit. Everything will work but we need to program the Arduino board, 00:04:29
is the only thing we need. So how can we program it? We click here on code and something appears. 00:04:35
Something is the programming window. There is already a block here, some blocks here, 00:04:43
we don't want them, so click and drag them to the left and they will disappear. 00:04:49
Well, our first program will be the blinking program. It's the first 00:04:55
program everyone learns when you are starting programming. The LED will be shining for one 00:04:59
second and then it will be off for one second. How can we program it? Okay, we are going 00:05:09
to use two blocks. Definir pasador en alta y definir pasador en alta. Pasador, I don't 00:05:14
like the translation. Pasador means a connector. There are 13 connectors here and because we 00:05:21
We are using number 13, we are going to take 13 and the same with this one, 13 here. 00:05:27
And this block will be useful to put it on and the second one will be useful to put it 00:05:38
off or low, that's why this one is baja. 00:05:47
If we connect this to block alta and then baja, the code, the program won't work. 00:05:53
Why? 00:05:59
Because we want it to be high for one second and then low for one second. 00:06:00
So we need to make it wait. 00:06:07
We need a wait block. 00:06:08
The wait block is here in control. 00:06:10
So we are going to use esperar un segundo, esperar un segundo, and now the program will 00:06:12
work. 00:06:20
mean 13 will be high for one second because it will be waiting for one 00:06:21
second then it will be low for one second because it will be way it will be 00:06:26
low for one second so now we have everything we have the LED connected to 00:06:30
the protection resistor the two components has been connected to the 00:06:34
Arduino board using the wires and now we can simulate it how can we simulate it 00:06:38
clicking on initial simulation start simulation we click on it and everything 00:06:42
is working and you can see the LED is on for one second, off for one second, and it's repeated 00:06:47
again and again and again, okay? 00:06:53
Now we can stop the simulation the moment we are sure it works, and now you will share 00:06:55
it with me. 00:07:00
How can you share it with me? 00:07:00
There's a share button here. 00:07:02
You click on compartir, share, and then on invitar a personas. 00:07:04
This is the link you are going to share it with me. 00:07:09
You can copy it, copy out, and then it's the one we are going to send to me by email. 00:07:12
for instance, but anyway, if I paste here 00:07:17
you can see that I will be able to open the same circuit again 00:07:20
so this is the link, this one is the one you have to copy and paste 00:07:25
to the email you are going to send to me and this way I will be able to 00:07:29
know if you have already 00:07:33
if you have really done the exercise, ok? 00:07:37
so good luck with your exercise 00:07:40
