A new application of the Antennino board that realizes a gateway using open-source software, which allows us to realize a control panel (Dashboard) for our wireless devices. We have introduced you, in issue no. 225, to our Arduino IoT version with a wireless connection, not surprisingly named Antennino; this board can operate, depending…
A device that makes Raspberry Pi suitable for industrial environments, an alternative to PLCs for automation control applications. In the 206th issue of Elettronica In, we featured the first device in the Strato Pi line created by Sfera Labs: the Strato Pi Server. This product, designed for industrial environments and based on Raspberry…
Let’s switch on the house lights using voice commands given through Google Assistant and the ESP demoboard for WiFi connection. Google is one of the most innovative companies in the IT sector and it’s testified by the exorbitant number of users who use its services: from the most widely used search engine to the…
A small jewel capable of detecting atmospheric pressure and temperature, designed for the construction of weather stations or applications where it is important to know these parameters, such as air mass meters and altimeters. Let’s try it with Arduino. We know Omron for the many industrial sensors it has produced and continues to…
Let’s build a system able to detect the movement of people and objects through a video camera and send alarm e-mails with Raspberry Pi 3 B +. The so-called Computer Vision or artificial vision is a research sector that deals with how computers can interpret visual reality exactly like a human being; it uses…
A small integrated SMD gives life to an excellent portable FM stereo radio receiver which can be easily created because it does not require the production of coils or the calibration of tuned circuits. The semiconductor industry continuously churns out new integrated circuits for all application areas and also for consumers and audio; among…
Let’s experiment with the OpenCV 4 library in real-time face recognition and smile detection project. In the article “Home automation with OpenCV 4” we have introduced the OpenCV 4 library for Raspberry Pi, which represents a powerful tool to realize applications in the field of image detection with a specific camera for Raspberry Pi….
Let’s complete the description of the modular development system dedicated to connectivity and IoT, deepening the discussion of the dedicated framework. Second Episode. In the article published in the previous issue, we introduced the Mercury System, an innovative development system, particularly suitable for IoT and connectivity-oriented applications. At that time we focused on…
Modular development system that simplifies connectivity and IoT applications: based on boards that can be combined as LEGO bricks, on a complete software framework. Allows scalability and modularity. The Internet of Things (or IoT, whether you prefer), ie the capacity of certain objects, equipped with sensors, actuators and wireless interfaces, to connect to the…
A multifunction platform built around BBC’s micro:bit educational board. It integrates a cute robot, a starter kit and also a board for experimenting. Some time ago, in a previous article, we have reviewed the micro:bit controller designed by the BBC as an object aimed to develop logic skills and competencies in the field of computer…
We use the platform based on the AMS sensors in combination with the Personal Computer and thanks to an ad hoc software we trace on the screen the spectrum curves resulting from the analysis performed. In the analysis of materials, spectrometry has been used for a long time; this is a metrology technique based…
We present an automation solution that provides the ability to control a series of relays, using the local wired Ethernet network. All driven by the new version of the Arduino Yún board. The project that we present is born from the almost simultaneous availability of two devices that, although of different origins, lend…
