And now if you don't want to buy your natural abode or use any hardware component, here is how you
can complete this course with just a simulation.
Note that even if you have no board and components for the course, I still advise you to watch this
lesson and get familiar with Tinker CAD.
During the course I will sometimes use the Tinker CAD interface for explanations.
And also it is nice for you to always have the possibility to test a programme on a simulation before
doing it in real life.
So what is Tinker CAD?
Well, Tinker Cat is a free online tool already used by Autodesk, and you don't need to do any installation.
Everything is happening in your web browser, so you can simply open a web browser and type tinker CAD
on Google and click on the first link, which should be Tinker CAD dot com.
All right.
And this is the home page from Chincoteague.
And you can go directly here.
Join now and you can create a personal account so you can choose to sign in with Google, Apple, Microsoft,
Facebook or email.
So just sign up using whatever method you prefer.
And once you have created your accounts, you can directly sign in and you will get to this interface,
the Tinker Card dashboard.
And on the left here, you will make sure to click on designs and then you can click on circuits.
You can choose circuits here.
So for you, it's going to be empty.
But as you go and create new circuits, you will see all your circuits here.
And so you can click on new and create a new circuit.
And this will open a new page.
This is kind of a workspace where you can build any secret you want.
So the name here will be automatically generated.
You can just change the name as you want.
So here this will be, for example, test.
And then so I'm going to zoom in a little bit then to build a circuit where you have all of the components
you want here on the right so you can directly search for components.
So for example, Arduino, you select Arduino, Arduino UNO three.
So this is the board we want to use.
So you can click on this board and put it here on the dashboard.
You can click here to automatically Zoom.
And if you use the scroll from the mouse, well, you can zoom in and zoom out.
So great.
Now you have your original world, which is a simulation.
And now what we need is to actually be able to write some code for this board.
So you have a here, you can click on this code button, this will open the code interface.
And actually this is not text code, This is a block interface.
And you are going to select here just text.
Okay?
We are going to write code directly.
You have a warning.
Are you sure?
Yes.
You click on continue and you have so you have an already existing program that we are going to see
later, of course.
And well, this is the same as writing code on the Arduino ID, so you can click on here code to toggle
the code editor and here you can add any other component at any time if you want to, and if you want
to start the simulation.
So basically, if you want to transfer this code into this fake ball, you click on start simulation
and now the program is inside the adeno board.
So you don't need to set up anything.
This is done automatically.
And if you want to actually change the code here, I'll change the circuit.
Well, you have to first stop the simulation so you can start the simulation.
Stop this action.
This is one difference with the Arduino ID is that once the code is running on your board in the original
ID, you can always write some new code, but not on the simulation.
You need to first stop the simulation and then change the code.
All right.
And as you can see, all change is saved.
So this will be saved automatically.
You can click on this Tinker Code button here to come back to your menu.
And here you have your circuit so you can create a new one if you want.
And you can just click here to go back to the previous circuit.
All right.
And now you are ready to create your first Arduino program, whether you use a physical Arduino board
with a hardware component or the Tinker CAD simulation.
