Make use of an ad hoc module by AMS in order to make a precious Arduino based tool. It will allow analysis of materials, including food and drink, through the spectrum obtained with a light stimulus and a sensor, and shown on the serial monitor. Spectrometry is an analysis technique that enables the identification…
Let’s optimize power consumption for our Arduino-like boards using specific hardware solutions and a dedicated software library. We recently had many requests about solutions to reduce power consumption for our Fishino boards, particularly from those – among the designers – who need to activate them for short periods of time: for instance, in…
Let’s learn all the aspects of the most renowned web hosting service, and familiarise with it, thanks to a sample application. In the previous post, we let you know Git and in particular, we focused on explaining how to use it in order to archive a firmware project on your PC and to…
Let’s learn about the firmware management and versioning tool that is at the root of GitHub, and to be able to use it. In order to become a good programmer, it is not enough to know the most popular programming languages, to know how to write the corresponding code, to create more or less…
The latest robot from Waveshare, it adds interesting features to the qualities of its predecessor. You were able to appreciate the instructional robotics platform on wheels called Alphabot, in an article dedicated to it, and you were able to see it in its version with Arduino controller. Alphabot, we remind you, is a robot…
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…
Created for the most famous social network, it displays in real-time the number of likes received by the related Facebook profile, through a giant 5-digit display. Since social networks were born, and Facebook in the first place, it became commonplace to express approval for a comment, a photo or a content in general (which…
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…
