Arduino Projects

If there is one key device to be named in the growth of DIY computing, it is undoubtedly Arduino. Countless projects, simple and complex, can be made with these plates. You can see our product catalogue in our Arduino shop.

Since the first model (Arduino UNO) was launched, from its country of birth (Italy), this community has not stopped growing. Not only has the number of official boards and models available continued to grow, but compatible models from other manufacturers have also been developed.

Thanks to the open spirit with which these boards were born and have always had, it has been possible to develop a multitude of Arduino projects.

It has managed to significantly lower prices. This platform has never stopped growing, positioning itself as a reference for learning robotics and programming for the young and not so young.

Your first robot, a self-sufficient vegetable garden or humidity control for a basement. These are some of the clearest examples of projects to make with Arduino. Take a look at this section to get an idea of how amazing this world is.

Comparative analysis of Arduino boards (official and compatible)

As with Linux distributions, Arduino also has a multitude of editions, each one designed for a specific audience or for a specific set of tasks. There is such a variety of official, unofficial and compatible models that it is not uncommon for people to be unable to differentiate the exact features of each of these wonderful boards.

For that reason, in this mega post we are going to detail all models official ones existing today, as well as exposing some of the interesting unofficial and compatible ones. You should bear in mind that the official Arduino models amount to almost a quarter of a hundred at the moment, and that there may be hundreds if we add the compatible and unofficial ones. ...

Create an Arduino robot with our kit

Arduino Robot

With cheap and easy-to-handle material, we are going to assemble a robotic base controlled by Arduino and can be programmed to control the two motors that guide the robot at will. In addition, over time you can add new gadgets to your Arduino robot to advance in the field of robotics or mechatronics.

The mechatronics is a type of engineering that encompasses other types of engineering, such as mechanical, electronic, control and computer engineering. In short, it is used to create automatic or intelligent mobile machines. After all, this is what we do when we work with programming, electronics and mechanical elements (actuators, motors, gears, wheels, ...).

How to remove moisture from your home: Part 2 of 2 - Extractor fan

Ventilation hole and probe finish
The automatic ventilation system finished and working

As we indicated in the previous post, in this one we will talk about the positioning of the extractor and details to be taken into account for the system to work properly.

It is possible to extract moisture directly by placing an opening to the outside in the lowest part and placing the fan directly (the coldest and most humid air tends to be in the lower part of the room), but in my case, being a ground floor in contact with the mountainside, I had to bring the humid air from below to the top, so I used 90 mm diameter PVC pipe, with a fan connected to it in the lower part.

How to remove damp from your home or premises: Part 1 of 2 - Arduino

Moisture extraction tube and external sensor

In this tutorial we will explain how to dehumidify a room in two steps; first we will detail the preparation and programming of the Arduino board. with which, by means of a relay and two inexpensive DHT11 sensors, we will control a small fan that will do all the work, checking temperatures and humidity. Then, in a second entry, we'll get our hands dirty by drilling holes in the wall and placing a PVC pipe with the fan connected to the Arduino. to extract the colder and more humid air from the lower part of the room, as well as placing the humidity sensors and the box with the Arduino, power supply, etc. I hope you enjoy reading it as much as I have enjoyed installing it; it has been a success; the humidity in a storage room that is in contact with the ground has dropped in one day from 90% to 70% saturation (while in the street there was a 65%).

How to control an LCD display with Arduino

LCD displaying "www.comohacer.eu"

We spend many hours sitting in front of screens, but few understand how they actually work. In this post we will show you how to programme a LCD display with an Arduino boardThis allows you to display messages on the screen and even use the functions of the LiquidCrystal library to create effects and display images.

This will be very useful, especially if you have a more complex project in mind where you need to display data on screenThe information obtained by different sensors connected to the Arduino, for example, can be used to monitor all this information and much more. You can monitor all this information and much more.
