Let’s create an alarm to be notified when doors and windows are open, even from a notable distance, using a modified LoRa TX palmtop. Long-range radiofrequency data communication technology, also known as LoRa, is employed in several fields, from IoT (elective use) to automation, to applications that were based on traditional transceivers. The versatility…
A new library for Fishino boards allows to easily send multi-device push notifications using Pushetta. Let’s try it out with our lightning detector. Since the name launch of the first board from the Fishino series, we have developed and proposed new versions and enhanced the software support, with the addition of firmware features and…
The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed…

Our Fishino boards are evolving, acquiring new and exciting features and functionalities. The renewal starts with UNO and MEGA. We are now going to explain to you what has changed. In the previous article, we introduced what would become the founder of a series of innovative boards compatible with the famous Arduino: the…
The electronic guardian who watches over our baby’s rest periods and environmental conditions of their room. Sometimes, when “browsing” the web in search of solutions to common problems, we happen to run into projects which are decidedly significant from the point of view of the use of resources, aimed at solving a problem that…
Do you have an idea and would you like the components to make it happen? Present it to us and we’ll give you the components to accomplish it! How it works Every day millions of makers and enthusiasts like you, make innovative ideas to meet their needs: there are those who make their home alarm alone, who…
Let’s start using our IoT boards based on Arduino architecture. In our previous posts, we presented Antennino, a special Arduino board with connectivity functionalities, capable of operating in Peripheral or Gateway mode. We stopped at the hardware description and configuration, promising to return to the topic to show you an example of use applicable…
It allows controlling devices such as lights, motors and even relays from a channel of a radio modelling receiver. The signal and the standard of servo controls were born to guarantee proportional control of utilizers such as electric motors for modelling and radio modelling, in order to set and maintain a well-defined angular position…
Let’s discover how to load the bootloader on our IoT board, so to prepare it for the usage. You learned about Antennino when reading the first part of this article, in which we presented the project and described the hardware, in detail. Let’s resume the discussion from where we stopped, that is to…
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The growing demand for portable devices capable of working where there is no power grid or it is not convenient to use it is…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
