A set of tools that – for an affordable price and without difficulties – is capable of identifying and verifying the features of BJTs, FETs, thyristors, diodes, etc. Until a few years ago, it would have been a utopia to have a very small, portable, relatively cheap and universal tool for the…
Let’s use a new Real Time Clock by Microchip, by making it available on a shield for two prototyping boards. First Installment. Many applications require an hourly information, that is locally obtained by means of circuits that are named RTCs (Real Time Clock) or RTCCs (Real Time Clock Calendar); among them are clock…
Having explained the theory, let’s see in practice the project of the SEPIC power supply. In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s…
A shield that provides 16 digital or PWM I/O using a single Arduino/Fishino I²C bus. Ideal for managing multi-color LED or servo motors. Arduino boards and compatible alternatives are really easy use and o powerful, capable of making countless applications, but they suffer from two strong limitations: the relatively small program memory and the…
Based on Arduino, it performs electronic light games by piloting a LED matrix thanks to a special multiplexing mode. In the “fast paced world” we live, moments when we can do whatever we want are rare and we have to cut them out from our routine, by skillfully balancing between the busy…
By making use Raspberry Pi, we created an easy to build 3D scanner to be used for the acquisition of three-dimensional models via a video camera and a laser 3D printing keeps on establishing itself, mostly thanks to the availability of more user-friendly 3D printers and price drops. Those who use a 3D…
A scalable board to prototype motion control applications for automatic balanced robot or any other robot on wheels. It was the 2013 when we presented a control board to make a clone of the famous SegWay: the OpenWheels project. In recent years, the focus on systems to stabilize unstable ones grew up sensibly….
Rethinking the popular Arduino: compared with the latter, it adds the implementation of the Fishino architecture, along with WiFi connectivity, a battery charger, etc… As we anticipated in the article in which we presented our Fishino MEGA (a board that is compatible with Arduino MEGA, and that is characterized by a great number…
The Fishino version of the powerful and popular board, Arduino MEGA: a revised hardware with a different power section. Not so much time has passed, since we presented our Fishino UNO, a board that is compatible with Arduino UNO and that is provided with interesting additional peripherals on board, among which a WiFi…
It allows to drive the ever-new 4 colour light diodes, by easily changing their brightness and colouring. Recently some multicoloured power LEDs have appeared on the market and, differently from the more common RGB LEDs, they incorporate a white LED, as an addition: they are named RGBW (Red, Green, Blue, White) just because…
It supplies Arduino with the WiFi connectivity and the external memory support on a SD-Card; it is based on a new module that is completely programmable, and offers the best value for money, with a very limited energy consumption that make it ideal for battery applications. It is not the first time that…
In this last post of the LoRa series we will see how to use the board, so to create a network composed of addressable and safe nodes. Semtech’s SX1278 integrated circuit, on which this shield is based, allows for a sophisticated and efficient communication in the LoRa (Long Range transmission) technology. This communication is…
