Welcome back.

So in this video, I want to talk a little bit about what you used to code for your Arduino projects.

So whatever you do in, aren't we know Project you're going have some type of art we know board, you're going, have your sensors, you're gonna have your motors at that time of thing, and then you actually have to feed code to your Arduino board.

So it knows what it's supposed to do, how it's supposed to interpret, uh, the inputs and then what it's supposed to do for the outputs.

So the big thing to remember whenever you're dealing with an Arduino board is that this is simply a microcontroller.

It is very important to understand that this is not a full flesh computer.

A lot of people get confused, they think aren't we know, and raspberry pi is same same but different that basically they're the exact same thing.

It's very important, understand?

No other than them being relatively inexpensive, there's a lot of difference between an Arduino and a raspberry pi.

A raspberry pi is an actual computer that happens to simply be inexpensive and run on something called an arm processor so you can put an operating system on a raspberry pi.

You can do all your normal computer re type stuff on a raspberry pi, and so, if you're going to do something like code for a raspberry pi, you have a whole bunch of options, right?

Whatever.

A lot of different languages were running a raspberry pi.

And so, just like if you're dealing with a normal computer, you will pick the language based off of what you're actually trying to solve for when you're dealing with an Arduino, it is not the same.

This is not a full fledged computers, just simply a microcontroller.

Basically, what you do is you feed it the environment variables, and then you feed it a loop.

So basically, there's a loop that just continuously loops, Um, and then that that that's all it does.

You can't install my sequel onto this.

You can't install a pathway onto this.

This assembly a microcontroller, you feed it instructions.

It does whatever those instructions are.

So for most people when you're going be coding for Uruguay.

No board.

You are going to be using what is called the Arduino I e.

Now to be clear, and you always have to be a little bit careful.

Whenever you talk about technology, there are other ways to code for the artery.

No board, but you'll figure that out.

Or we'll talk about that when we get to that point.

For the most part, especially in the beginning, when you're hobbyist when you're playing around with this stuff, you will simply use the artery.

No, I e.

Now a lot of people ask what programming language do you use for the art We know and that's again, it's kind of it's kind of one of those fuzzy, fuzzy answers.

So basically, when you're coding for the art, you know within the artery No, i e.

You're using what are called C or C plus plus of functions.

So there are functions that have been created that will turn your instructions into c++ went.

So whenever you click on the compile button, basically what happens is the code that you that you've written gets turned into C C plus plus, so how this gets coated to C plus plus the basically what the code that you're right looks a lot like C C plus plus, but it's not really that you're coding and C C plus plus, you're you're writing functions that are then compiled into C C plus.

Plus, if that makes any sense, the big thing to understand here if you're starting to get a little bit confused, is you use the artery.

No, I d e you create a sketch with in what's called the yard, we No, i d e.

You are going to have to write out the code within that I.

D.

E.

That idea is going to compile into C C plus plus, and then that is going to upload the code to the board.

So don't get lost too much in the weeds with the whole You know what programming language that you're going to use.

That type of thing is just important.

Understand?

You used the i d to write the code that's gonna get compiled and then showed up to the road.

We know once you learned a whole bunch more about how this stuff works, then you can start to get a little bit more fancy.

That is one thing to understand whenever you're dealing with the Arduino again anything in the d i y Tech world, there is the simple way to Theo There is reinventing the darn wheel you will as you go As you go, you will learn all kinds of fancy new ways to code for the aren't we?

You know, upload code of the aren't we know there's all kinds of stuff that you can D'oh.

But in the beginning, in the beginning Ondas long as it works for you Just remember you do the yard.

We No, i d e you're right.

Your code and what's called a sketch that gets uploaded to the board That will do you for a long time if you want to know more about the different ways to code for a DWI.

No, there are other options out there, but it's one of those options that you don't have to worry about this boy.

So let's actually go over the computer so I can show you wear toe downloaded the artery?

No, I d from on then show you a little bit about the artery.

No, I d so that you get comfortable with that environment.

So to make life easier on how to find the Arduino i d.

E really?

The best thing that you should do is go to Google or whatever else and plug in, Aren't we no space I d e and see what the search results are.

Basically, what should pop up first is hardly know software i e.

It's important that you download the software from Arduino dot cc.

So the main website for all we know is not artery no dot com.

It's actually hard, we know dot cc.

So when you go searching for the Arduino I d e look for whatthe link says.

And if the link says Arduino dot c c plus something like software and there that is what you're going to be looking for, then all you do is you.

You click on the link and you come here.

There is a web editor.

We're not gonna talk about that today.

What we're going to be dealing with today is actually being able to download the artery.

No, I d.

And you can see that they've ported the artery.

No, I d too many different types of operating systems.

So there's Windows versions of the I D it Windows Hap Mac OS X Lennox for the X 86 processors and Lennox for the arm processors.

Soem or less.

Whatever operating system you're using, they should have an option here for you.

And then from that you just click on on this, you download and install it.

I've seen many of the different versions of the artery.

No, I d e and horseshoes and hand grenades.

They all seem to be about the same.

So I don't think you'll have, like, a different experience if you were using the Windows version versus whether you're using polemics version.

So once you download and install the Arduino I d eat, you could just open it up.

So for maybe Windows?

Oh, you go to finder your applications and you go, Where would we know is and you just open it up and this is what it's going to look like.

Eso these air last projects that I was working with and we can see these are different sketches that I was working on.

Now, if we go up here, we take a look at the basic configurations and the settings for the Arduino i d.

You go here, we take a look at preferences preferences air Pretty basic.

You know what the sketchbook location is going to be?

Editor font size.

You know, that might be something you want to change.

Verified code after upload s O.

This is an important thing.

So when you're writing the code, you can have the artery.

No, i d e automatically verifying for you.

So if you don't have this check mark checked, basically what'll happen is your code just simply gets uploaded.

And then whatever happens, happens.

If you have this checked it will.

It will actually verify to make sure that you haven't screwed up the code.

So that's an important thing.

Check for updates on start up.

And there's a few different settings here that you could work with later again.

Got some network settings.

Uh, then we go from that we go to file.

This is the normal thing.

We have sketchbook, you know, open new, open, open.

Recent sketchbook s.

So basically this these are the sketches.

So any any time we create this kind of script, So in the yard, we know world a script is called a sketch.

So any time we do that and we created here, it will go into our sketch book.

The other thing that's kind of cool here is we have examples.

So what examples are is, these are sketches that have been created by the art we know folks so that you can simply use them on then and then change them as need be.

So there's a basic one here, such as Blink.

Basically.

You can open this up, and so this sketch here blink allows you to make an led light blink on your Arduino board.

And so one of the nice things is, if you're doing something where it's kind of been done before you like a blinking led light on a board, you can go.

You can open up the example.

You can tweak it as you need it to be tweet on.

Then you can simply use that code.

From there, you go over to the edit.

There are some interesting options here, such as copy for forum or copy as HTML.

Now let's say you're having problems with your your sketch again, especially if it's a longer sketch.

Not not a short one like we're doing most of these projects.

Let's say something longer and you actually need help with it.

Well, if you try to simply copy and paste code from your sketch toe a website or to a forum, most likely it will fail out because there are security precautions.

Basically, there's there's validations within most websites, so that code cannot be directly inputted into that website.

So if you do a copy as HTML or copy for Forum, this adds all the HTML tags in that type of thing to make it eight email text so that you could actually post it into something like a forum.

And it won't fail with a validation.

So those are some things to think about.

Comment a nun comment Increase in Dent.

You know, increased font size so on and so forth we can go over to sketch.

So sketch has this verify and compile.

So this what What you can use this for is if you don't necessarily want to upload the sketch to your board right at this moment in time.

But you just want to verify that there is no glaring problems with your code.

Basically, you could just click on this, verify and compile and it will go through and it will verify your code and compile it to make sure that it will actually function.

This is important.

So if you're like me and you do stupid things like forgetting Semi Coghlan's or you put semi colons where semi colons aren't supposed to be or you forget a bracket or something like that simply got going up here to sketch to verify and compile, it'll go through and it will show you those problems before you actually try to upload it to the board.

You can do the upload here, there, and then there are some some other things here with export compiled binary wth.

The other thing is, there's something called libraries, so we haven't dealt with this yet, But when you're dealing with things such as servos, when you're dealing with things such as network shields, basically what libraries are his libraries are all the code that allows those particular things to function right.

So basically what you can do is you can add to the library to your code, and then the Arduino i d.

E essentially ads all the code to make that device work within your project without actually having to to write it into the script yourself, eh?

So you've got all kinds of different our libraries here, GS and mouse Robot control Robot.

I are so on and so forth and you click here you go to manage libraries.

And so with manage libraries, you can actually install new libraries.

So if there's a library that's not installed with you in your I d e, that's one of the things that you can do.

There s oh, that's some of the important things we're looking at when you're looking at this little sketch menu, then you go to tools.

Uh, you know, there's a few tools here that a useful auto format again.

So if you're like me, I don't really like Cody.

And again, whether it's whether it's spaces or tabs or anything else.

Whatever I write code, it looks horrible.

The cool part about auto format is it basically auto formats for you, right?

So if I'm here and I have, you know, this and it looks like this, I go here to tools auto format.

Whoa.

So, again, auto format.

If you're doing this for any type of class.

Whether it's a high school class or college class, I highly recommend you use on a foreman because the thing is, when you verify and compile, it won't do that auto format for you.

It will simply go through and verify that the code will work the auto format.

What that does is goes through and make sure the code is basically human readable s.

So that's a valuable thing.

Go here to manage libraries again.

A different way to be able to upload libraries and such to the Arduino i d e.

We'll talk about that later.

Something called the serial monitor S so we'll use a serial monitor in many projects.

This is how you can actually read information from the Arduino.

So let's say we're doing a temperature project, so we put it an analog temperature sensor into the Arduino.

And then we would simply want to read what temperature that sensor is telling us.

So we can start the serial monitor and actually be able to read that temperature directly from the Arduino board.

The serial plotter.
