Having a personalized domain for our website has several advantages: it acquires a professional image, gives credibility to users, protects the name of the site on the Internet and if it is short you allow them to access more easily because it is easier to remember. That is why before buying a domain you must know certain things and clear all the doubts you have.

Although today these two large companies have become one (Microchip Inc.), the great Atmel technology has not ceased to exist and will not, at least what was initially designed by Atmel.

When we just started in the world of microcontrollers perhaps many of us ask ourselves some occasion, which is better? Atmel (AVR) or Microchip (PIC)? It seems that this question was passing from generation to generation.

While it is true that the PIC community is the largest in the world we can not ensure that its technology is really better than any other microcontroller, it is necessary to investigate a little more about the characteristics of each of them before issuing an opinion.

So this post tries to present the main differences that the AVR microcontrollers and the PIC have in a general way, it should be noted that thanks to the union of these companies are currently in production new models of microcontrollers with both technologies.

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 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.

If you have decided to acquire an Arduino but you may have noticed that there is a great variety of them in the market and now you do not know which one to buy, this post is for you.

In this post we will let you know the capabilities of each Arduino model so you can make the best decision when buying one.

As we have seen before perhaps the most important thing in our training as developers or programers is learn to be organized, this way we improve our quality and save time.

In this post we will give you some recommendations to learn to develop and/or to program.

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.

If you want to learn to develop, the best site to start is W3Schools.
It's undoubtedly one of the great sites to learn how to program, in the site you can find tutorials for users who are just beginning to learn and even tutorials for advanced users or experts in the subject, the site also has test sections where you can see examples of the subject you are seeing at that time and even practice with the knowledge previously acquired.
