A multirole board, that stands out for its very low energy consumption and the possibility to be remotely programmed, emerges in the rich landscape of the IoT modules. When talking about IoT, we usually refer to devices that are powered by batteries and that are scattered in the environment, for the purpose of acquiring and…
It is installed in cars, and thanks to a detector placed on the child seat, it warns us – via SMS or phone call – if we get away without bringing the child with us. Among the most saddening (and at any rate, infrequent) accidents in the news, there are those of parents that…
When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended as the possibility to define the operating priorities and to momentarily disconnect the ones that may be…
It enables a selective disconnection of a maximum of 7 users, once the maximum power set is exceeded, and by selecting the priorities, so to disconnect the less important ones first. Supervising the electricity, intended as both the monitoring and the management and even as a possible limitation and optimisation, is a topical issue…
This circuit provides timed access to pay services such as games, showers, blows dryers and various types of vending machines, thanks to a coin counter and a display interface. In the applications involving the paid access to certain products or services, the electric or electronic “coin-operated actuators” are used, which are devices capable…
A robotics development platform based on a two-wheel mechanics plus pivoting wheel on which you can prototype applications, controllable with popular Arduino Uno, Raspberry Pi 3 boards or both. Robotics is one of the most engaging parts of electronics because it can combine different fields of knowledge and skills in the same project; in…
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”…
[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…
