The first thing we have to know about Arduino is that it is not just one thing. Unlike other boards, this project is characterized by offering open hardware bases with which other developers can create their own projects through these plates, which can be the most varied. With that foundation, each creator can create his own single-board microcomputer depending on what he needs to develop: a smart doorbell, a scale, or even a vending machine. Some plates oriented to the Internet of things and to make creation and development accessible to everyone.
what is arduino
To explain what Arduino is, you have to go to its origin. It is a project that was born from the hands of several students from the Institute of Interactive Design in Ivrea, a town in northern Italy. From the need to have their own microcontroller for students that was cheaper than the one used until then, the popular BASIC Stamp, the idea of creating an open hardware product ended up emerging.
Thanks to the programming language offered by Arduino, we can record on the microcontroller the necessary instructions to create our plate according to our needs, according to the project that we are going to carry out with it later. It has a connection for different types of peripherals depending on the use that we are going to give it. It can be a keyboard, a sensor, a camera… It also has an output interface, in case we want a screen to output the data.
With an Arduino we can create a standalone device, like a clock or a scale for example, but we can also connect it to existing ones and use the Arduino to improve its features, adding a motion sensor to a smart doorbell so that it turns on even before the button is pressed. As we have said, it is not a single plate, there are different plates with different sizes, colors and prices depending on what the needs of our project are.
Examples of projects with Arduino
We can do thousands of things with these plates… Although the ideas will vary as much as we want when we know how to take advantage of them, there are some ideas that we can find on the Internet and that allow us to see how useful it can be.
An autonomous garden system. For example, from the Makezine ideas website we found a autonomous garden system. Thanks to the Arduino boards and several sensors that we can connect to them, we can create a gardening system with which our plants can be almost autonomous. We will control the humidity, light, water and nutrients they receive and we will be able to stop worrying once the care of our plants has been programmed.
Fingerprint reader to open the garage. In another of the best ideas websites in the sector if you have a Raspberry Pi or Arduino, instructableswe found a fingerprint reader for your car park With an Arduino board we can make a fingerprint detector that allows us to open doors, like the one in the garage of our house. We can also add a small screen to send an instruction message or a correct or erroneous reading message.
Voice controlled blinds. Also on the same website as the previous one you can find how to do blinds you control with your voice cheaply and without expensive home automation systems. Continuing with the sensors, we can use our Arduino board to control various mechanisms of the Internet of things in our house. For example, the blinds. There are many houses that already have this system automated, but we can add one more functionality and it is that of voice operation, which, when recognizing our order, raises or lowers the blinds of the house.
Although they are just some of the many that we can find on specialized websites where users let their imagination run wild and help us with step-by-step tutorials to get the most out of these objects.
