Programming WiFi on Arduino with the WiFi101 library

Arduino and the WiFi101 Library

(Italiano) La libreria WiFi101 permette di poter utilizzare in maniera programmatica la tecnologia WiFi su sistemi Arduino potenziati con Arduino WiFi Shield 101 o utilizzando direttamente la scheda Arduino MKR1000 che ha il WiFi integrato. Inutile dire che questa libreria è uno dei mattoncini fondamentali per lo sviluppo e l’utilizzo di Arduino come soluzioni IoT.

Adafruit Circuit Playground – a new Arduino compatible wearable board

On the big stage of the Arduino and Arduino-compatible electronic boards there is a new protagonist: Circuit Playground. This board is developed and distributed by Adafruit, and its name is very meaningful….this board is a “playground” for all makers.

In fact, it contains all the features of an Arduino LilyPad board, such as flexibility for wearable designs, but at the same time contains some electronic components (such as multicolored Led, buttons and light, sound and temperature sensors). With these components already integrated, you can create your projects and test them with only this board. Let’s look at it in more detail in this article.

LCD1602 – Using a liquid crystal display LCD with Arduino via I2C

During the building of your projects for Arduino, you’ll often need to read the output data directly from a LCD display. In this article you will see how to mount a LCD display on your Arduino using the I2C communication. Finally you will see how to program it with a simple example showing how to display text on the display.

Arduino: measuring the Earth’s magnetic field with the magnetometer HMC5883L

This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on  AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth’s magnetic field. This magnetometer HMC5883L has within 3 magneto-resistive sensors arranged on three perpendicular axes (the Cartesian axes x, y and z).
