Good morning! So you've already registered in the www.tinkercad.com website, so you'll
00:00:01
be able to log in and you'll see something like this. In Tinkercad.com, there are different
00:00:10
possibilities. We could create 3D designs, for example, but now we're going to create
00:00:15
a circuit. So we click on this label, Circuits, and here it shows that there have already
00:00:21
been some designs made, but you will not have any yet. So you're going to click on
00:00:27
create new circuit. If you click on it the screen will change and something
00:00:32
like this will appear. Here on the right we have our library of components that
00:00:38
we will click and drag to use, but the first thing we need for this exercise is
00:00:44
here in the basic components library. So we will scroll down a little bit and
00:00:50
find the proto board. Click and drag it and now it will appear on the screen. The
00:00:55
proto board is a way to connect things, we'll learn more about it in a minute.
00:01:02
The next component we need is the Arduino board, so click and drag. We will
00:01:05
also need an LED. An LED is a tiny bulb, a really really small one, and we will need
00:01:11
a resistor. So now we've clicked and dragged and we have everything we need
00:01:18
on the screen but the first thing we need to change is the value of the resistance this one
00:01:23
by default is in kilo ohms but we need to change it to 220 ohms and we have to be sure that instead
00:01:32
of having kilo ohms we have ohms so now we have the resistor and the resistor has to be connected
00:01:41
to the led because the arduino board will provide a lot of energy and the led doesn't support all
00:01:50
of the energy that will be provided so the resistor will take part of that energy and
00:01:56
that's why it's called a protection resistor now the resistor is connected to the led
00:02:02
why is it connected well you can see that there are five green slots and it means that these five
00:02:09
slots are all connected everything that is connected to one of these five slots
00:02:16
is connected because there is a metal stripe under the plastic so every one of
00:02:21
the five is connected but you can see that all of these are vertical but
00:02:28
there are also four long horizontal lines there's one here there's one here
00:02:35
down here and down here and the rest of them are vertical so now the resistor
00:02:44
and the LED are connected through these five vertical slots another thing we
00:02:51
want is to connect the Arduino board to the LED so we're going to connect them
00:02:57
using wires using wires is really easy the only thing you need to do is click
00:03:02
in here and we are going to connect it to the ground tierra first the color of the wire will
00:03:09
choose it'll be black because that is the usual color for ground connection and ground connection
00:03:18
in this context means the negative terminal of the battery the arduino board will work as a battery
00:03:26
a battery that can be programmed and we will change its behavior according to what we want
00:03:32
but it's still a kind of battery. So now the ground is connected to the straight part of the LED.
00:03:37
There are two parts. One is straight, the other one is not. The one that is straight is called
00:03:44
the cathode in English and the bent one is the anode. The wire is always connected to the ground
00:03:50
or the one that is usually black has to be connected here and the other one will be connected
00:03:58
to connector number 13. Why 13? Because we want to. So now we have a closed circuit.
00:04:04
This is the negative terminal, and the negative terminal is connected to the LED and to the
00:04:14
resistors using these five green slots. So we have a closed circuit, everything will work,
00:04:20
but now we need to program the arduino board so in order to program it we click on code and
00:04:28
something appears here with the programming window there are already some blocks here and
00:04:41
we don't want those so we're going to click and drag them to the left and they will disappear
00:04:46
our first program will be the blinking program it's the first program everyone learns when you're
00:04:52
starting to learn programming. We want the LED to shine for one second and then
00:04:59
be off for one second. So how can we program it? We are going to use two
00:05:03
blocks, Definir Pasador and Alta. The translation is not the best but
00:05:13
Pasador means connector. So there are 13 connectors here and because we're using
00:05:20
number 13 we are going to program by selecting 13 and then the same for this one and this block will
00:05:27
be useful to turn it on and then the second one will be useful to turn it off or low that's why
00:05:38
we're changing it to Baja if we connect these two blocks the high and the low the program will not
00:05:46
work well why because we want it to be high for one second and then low for one second so
00:05:56
we are going to need to make it wait so we need the delay block the delay block is up here in
00:06:03
control so we're going to select it and attach and now the program will work 13 will be high
00:06:10
for one second and then delayed for one second and then it will be low for one second and then
00:06:20
it'll wait another second so now we have everything we have the led connected to the
00:06:28
protection resistor the two components have been connected to the arduino board using the wires
00:06:34
and now we can simulate it by clicking in this initiate simulation so we click on it and
00:06:40
everything is working now you can see the led is on for one second off for one second and it's
00:06:47
repeated again and again and again so we can stop the simulation as soon as we are sure that it
00:06:53
works and now we're going to share it with your teacher so there's a share button up here you
00:06:59
click on it and then invite other people and this is the link you're going to share you can copy it
00:07:05
and send it by email for example if i paste it up in a new tab you can see
00:07:13
that i will be able to open the same exact circuit
00:07:20
again here it is so this is the link you have
00:07:23
to copy and paste that you're going to send
00:07:27
and this way the teacher will be able to know if you've already done the exercise
00:07:29
So, good luck!
