The ESP32 from Espressif is one of the most popular low-power microcontrollers with integrated WiFi and Bluetooth on the market. That is why we have decided to share a tutorial with you on how to get started with the ESP32 and Zerynth Studio. As an article on the Espressif website states: “Zerynth has provided the…
Just over a year ago we have introduced our first Arduino-like 32-bit board, called Fishino32 which was characterized by the format of the widespread Arduino UNO (but also of the Fishino UNO), although equipped with a 32-bit microcontroller capable of exceptional performances, when compared to the average prototyping board of its kind. We have…
In the first installment, you had the opportunity of learning about our energy meter, and of learning about its details, with special attention the technical ones. Our energy meter is based on the coupling – by means of two measuring transformers – to an integrated circuit, that enables the detection of the values as…
Thanks to an innovative module, it analyses the electrical grid parameters and the consumption, by supplying them – via USB – to a computer, on which a dedicated software enables to display, collect and use the data for different applications. First installment. It is common to worry about how much electrical energy is consumed,…
Let’s test the D7S by Omron, the world’s smallest seismic transducer, and create a seismograph capable of a sensitivity and an accuracy that are comparable to the ones found in professional tools. Each day, thousands of earthquakes occur on our planet, but most of them cannot be perceived by the population (as they…

We are going to build a robot on wheels controlled from the “Blynk”…
Palmtop transmitter to couple with the LoRa Shield to execute longer-range radio commands. Among the longer distance radio transmission technologies with low energy consumption, there was one in particular on which we have focused our attention, it is the one LoRa (Long Range) produced by Semtech (www.semtech.com) with a product based on it, some…
[bctt tweet=”A transceiver unit to broadcast audio MP3 files over Wi-Fi” username=”OpenElectronics”] In this article, we want to propose you what can be considered as the natural evolution of project Ethernet Broadcaster; the goal is still the same, i.e. allowing broadcasting of music or customizable audio messages. Besides adapting to the ever-growing trend of…
LAN interface with 4 relays, 8 programmable I/Os and 4 analog inputs, IoT-ready. How many times have you read or heard about the Internet of things (Iot)? The Internet of things is an expression that is becoming more and more popular lately; it represents the expansion of the Internet into the world of objects…
Is a storm on its way? Let’s find out using a circuit based on a sensor to detect electrical shock in the atmosphere capable of letting us know how near and how strong it is. Meteorological centers can monitor, besides atmospheric parameters in order to estimate rain probability and volume, also storms and their…
The Tactigon is a board for wearable applications prototyping, able to recognize gestures and different kind of movements, thanks to the firmware availability and simple programming which are typical of the Arduino environment. You knew about it In the introductory post published issue and in the first proposed application; now you can see it in…
We test with the wearable application and three-dimensional gesture detection prototype device, by making the GPS receiver interact with the onboard IMU in order to improve position detection process. The Tactigon, as explained in the dedicated article n issue No. 220, is an intelligent device (and moreover Arduino-compatible) that allows to crete a controller…
