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.

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.

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.
