Training

In order to carry out an invention or DIY projectWe will need to have some basic knowledge, which will be provided by the training The following is a list of the areas that will influence the invention. Before taking the risk of starting a project, it is best to have a good foundation of training through these articles.

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.

Connect your Raspberry Pi and your Android device via SSH

Raspberry Pi and Android

SSH (Secure Shell) is a protocol for accessing remote machines over the network. With this technology we can connect our Raspberry Pi to our Android smartphone or tablet to control it. Thanks to SSH we will have access to the RPI console from anywhere...

The procedure is not at all complicated and can offer us many alternatives, such as controlling our Raspberry Pi remotely via our mobile phone wherever we are.

Arduino animated Nativity Scene: the woodcutter

Bethlehem Portal with Arduino

Christmas is approaching and with it comes the tradition of setting up the Nativity Scene. Something so traditional can be linked to new technologies, as we shall see: why not modernise the Nativity Scene and use Arduino to bring the figures to life? Imagine the Ferris wheel spinning, the character in the well pulling out the real bucket, the sawyer sawing his trunk, the blacksmith hitting his anvil, the woodcutter chopping with his axe (which will be the one we will deal with in this article), controlling the lights, creating artificial sounds, ... Well, stop imagining and get down to work with this Christmas project to "arduinize the Nativity Scene".

Note: Obviously everything can be controlled from the same Arduino board, using the different connections offered by the board and extending the code of our sketch, achieving a "living" Bethlehem with a single board.

Home automation with Arduino: automatic climate control

Symbol for cold heat

A home automation system makes life easier and more comfortable. Now we can create an inexpensive automated system with Arduino, without the need for expensive PLCs and home automation devices.. The system can be installed in a living or working area to ensure that we are always at a comfortable temperature.

The experiment consists of creating a system that measures the ambient temperature and can switch on a heater or a cooling system, depending on the temperature detected. In this way, it will constantly maintain an ideal temperature in winter and summer without us having to lift a finger.

Arduino control via Raspberry Pi

Raspberry Pi USB Arduino

Arduino and Raspberry Pi are not two unrelated products, together they can make quite an interesting symbiosis and allow you to expand the range of possibilities of an Arduino board alone. You can also learn how the communication between software and hardware works to capture the essence of what is going on in your computer every time you perform an operation.

That's the great thing about Arduino and Raspberry Pi, you don't just create, you learn. And that's why they are two very powerful friends for your projects. In this article we show you how to make the links between Arduino and Raspberry Pi in order to be able to control your project Arduino using the software we created on the Raspi.
