Hello, guys, and welcome back.
So I have obtained the original idea, which you have installed in the previous lecture, and this is
where we are going to write our programs and then we are going to upload it to either Audrina Onoe or
to our E.S.P 32 or what we call the MCU.
But first, before we do that, we need actually to make sure that we have installed the right board
library that supports them.
See you.
To do that, we need to go to tools and click on board and check the board manager.
We need to click here.
And I want you to type note MCU.
Now, I have it already installed, so all you need to do is click on install and then you will have
the library that will support our not MCU, which is the main part we will to use in order to create
Iot applications after you click on install.
If you go to the board here again in Tools, you will see this SB eight two six six.
And simply you could go and choose Node and see you now choose the latest version you see here.
Click on it, and the moment you connect it, you should be able to choose the boat.
Right now I have my note MCU in my hand and I have blocked it then into my computer.
Now, if I go to Jules and go all the way down to ports, I will see that port aid is activated.
Now I'm going to unplug and you'll see that the port is great and I have unplugged it.
And as you can see, the port is not there anymore.
So if you are having trouble and the port here is great out, it means that maybe your device driver
is not really installed and you need to install it.
Usually if it is an original one, you won't have such a problem.
But if you get a cloned board, this is where stuff starts to get tricky and you need to search for
your driver on the Internet because, well, cloned board are not supported natively and you need to
get the driver from the manufacturer that you bought it from.
So I'm going to plug it in again and I'm going to go back and you need to choose the points or click
on CM eight.
It could be any number depending on the USB port you are using.
In my case, it's about eight.
So it's come eight.
And let's say, how are you going to test this?
It's very simple.
You just create a new example sketch if you got two examples and click on digital and well, you could
just go to basics and click on the link.
This will let the lead blink on your board so it will open a new sketch like that.
It is just some instructions in order to blink, you led you already know these instructions, we have
already talked about this in the Audrina section.
So all they need to do is just go back should the comments already selected and just click on upload.
Now, the sketches compiling as it is writing here.
Now we are uploading.
And we are done.
Right now, the lead on my not MCU is actually blinking, indicating that the upload is successful.
So this is the first step you would ever do.
When you connect a new board, you make sure that the board is installed in the board manager, and
then you make sure that you have selected the right board here.
And then you click on upload using a blink sketch like this one, and you should see the Leidy blinking
on your board.
So by that, you know that the communication between your original idea and your board is successful.
