This topic was an important factor for the creation of HTML5, because previously when we wanted to place our users some music player or video, only could interact those users who accessed our website through the use of a computer, being unable to enjoy this, the users who accessed a mobile device or tablet.

For many users this can be very frustrating, and it is not for less considering that currently most of the users who surf the Internet do so through the use of a mobile device or tablet.

In this post we will introduce you to some applications of the <div> element in HTML documents, because perhaps this is the most important element in the creation of websites after the basic structure of an HTML document.
This element is used to define a section or block of content, to be able to apply different styles and even allow interaction with it through the use of Javascript, PHP, or any other programming language.

Using a development software is very important, in fact it could be considered as indispensable because if we did not use it we could hardly develop, at least in this type of programming, at some point you asked what is the best software? or wich is the most convenient to use?, we have a surprise!, because the answer to all the above is that it is different for each person, because each of us has different ways of develop and perhaps the software that for someone is more efficient to another one seems boring and does not attract attention.

The CSS (Cascading Style Sheets) code, describes how HTML elements should be displayed on the screen of the user accessing our website.

When we just started to learn CSS many of us believe that it is really hard to understand and use, because unlike HTML this type of programming uses more elements, after a while it becomes easy to understand because practically the only thing we do is improve the appearance of the website using colors, shadows, sizes, shapes, etc... things that we know since childhood.

The use of Javascript allows websites to be more dynamic and interactive, compared to only HTML elements and perhaps this type of programming is one of the most complex focused on the development of websites, because it requires large amounts of development time.

This time we will show you how to use the arduino outputs to turn on a led. For this we will explain the basic principle in addition to the connection scheme.

Although some sites on the Internet show you that it is possible to connect an LED directly to the digital or analog outputs of Arduino this is a bad practice and we will address this topic later, so we recommend you read the contents of this post completely.

This post can be used on other platforms than Arduino, even with a microncontroller without any type of board.

In this post we will show you some basic examples about HTML, do not worry if any of the examples include tags that you have not yet understood because you will learn about them later.

When we first started learning HTML, we must understand that every website needs a basic structure through which everything can be properly organized, in addition to ensuring optimal performance in any device, this basic structure is commonly known as an HTML document and it is standardized.

This will be the first of several post on how to create our first page on the Internet, although we had already done a tutorial on how to create our first website this was never really online and only we could access it because it was in our computer, so this time we'll show you how to create a website that users around the world can access.

First of all, we need to know: Why is it important to learn to create a website?
Currently there are several reasons why it is important to learn to create a website and then we will explain some of them.

It is a law postulated by the mathematical physicist Georg Simon Ohm which tries to explain how electricity behaves, so it is closely linked to the values that correspond to the basic units of any electrical system such as: Intensity, Voltage and Resistance.

Today we will learn to calculate the resitance for the LED diodes. Let's see what is the ideal resistance to connect an LED without it going to damage or degrade.

To calculate the resistance, we must consider 3 important values:

* With which source we are going to feed the circuit (In this case 9V).
* Ideal working voltage of the LED diode.
* Maximum current supported by the LED.

Important: The values that correspond to the working voltage and maximum current of the LED diode are different according to the color, size, shape and even the company that makes them, so we recommend investigating about your model. The data provided here is relatively similar to what you can obtain for 5 mm LED diodes.

Arduino is part of physical programming, meaning that the programming we do will have interaction with the physical world. A clear example of this is to move motors, open doors, turn on spotlights, make LED sequences and use different types of sensors (Infrared, humidity, gas, ultrasound, etc ...).

Basically it was designed as an educational tool to be able to program the ATmega microcontroller, in this case the Atmega 328P-PU that belongs to the arduino uno.

Arduino is part of what we know as collective intelligence, which is achieved through the internet through the development of open source and open hardware, that is, all the hardware and software documentation of the card is released to the public so that anyone can develop, improve or extend it, including its development platform (Arduino IDE).

In this tutorial we will learn to create a small test using the windows console and batch script language.

To begin we have to take into account some of the commands that the windows console uses.
Below we show you some of the commands and we explain to you that they serve.

The design responsive is focused towards an improved interface for web browsing on mobile devices. The main objective of this type of design, is to improve the appearance of the websites with respect to the type of device with which the user is accessing. This kind of design uses code HTML5, CSS3 and Media Queries.

We have seen before the websites involve the utilization of the code HTML and others.
In this tutorial will learn to create the classic "file.html" who places online website.

Having a well organized code is important, because when it comes to finding errors in it, it becomes tedious and we can even think about starting to program again. Also a well-organized code will help us when carrying out any project, especially when we use some complicated programming language.

A developer is any person who "develops" any application, software or website, through the use of programming languages.

Some of the languages known and used for this are: HTML, Javascript, SQL, PHP, ASP, XML among others.
The previous languages refer to languages used in website development.

The language for building web pages.

HTML is a programming language, in this language websites are developed.
Yes! this site is written in HTML and other languages how to Javascript.

HTML is one of the languages of programming with more instructions and more easier to learn.
The basic tags in this language are:
