Regolare la luminosità di una lampadina (bassa potenza) a 12V con un transistor NPN 2N2222

Posted on by Michael G
In questo video, vi mostrerò come regolare la luminosità di una lampadina a bassa potenza (12V) utilizzando un transistor NPN 2N2222 e un Arduino. Questo progetto è ideale per chi vuole imparare a controllare la potenza fornita a un carico variabile utilizzando un transistor e il controllo PWM (Pulse Width Modulation) di Arduino.

Cosa Imparerai:
Componenti Necessari:

Arduino (qualsiasi modello)
Transistor NPN 2N2222
Lampadina a 12V
Resistenze (per limitare la corrente)
Breadboard e cavi di collegamento
Alimentatore 12V (o batteria)

Principio di Funzionamento:

Come funziona un transistor NPN
Concetti di base del controllo PWM per regolare la luminosità
Connessioni Elettriche:

Schema di collegamento tra Arduino, transistor 2N2222, e lampadina
Come collegare correttamente il transistor per gestire la potenza della lampadina
Codice Arduino:

Scrivere il codice per generare segnali PWM con Arduino
Esempi di codice per variare la luminosità della lampadina tramite un potenziometro o comandi digitali
Test del Progetto:

Come caricare il codice sull’Arduino
Verifica del funzionamento del sistema: dimostrazione della regolazione della luminosità della lampadina

Avvertenza:
Assicurati di seguire tutte le precauzioni necessarie quando lavori con l’elettronica per evitare danni ai componenti o a te stesso.

Drupal Core News: Announcing Drupal Starshot sessions

Posted on by Michael G

A few weeks ago at DrupalCon Portland, I announced Drupal Starshot, a project to create the new default download of Drupal. Built on Drupal Core, Drupal Starshot will include popular features from the contributed project ecosystem. It focuses on delivering a great user experience right out of the box. Drupal Starshot builds on recent initiatives like Recipes, Project Browser, and Automatic Updates to elevate Drupal to new heights.

The response has been incredible! Hundreds of people have pledged their support on the Drupal Starshot page, and many more have asked how to get involved. Over the past few weeks, we have been planning and preparing, so I’m excited to share some next steps!

We’re launching a series of sessions to get everyone up to speed and involved. These will be held as interactive Zoom calls, and the recordings will be shared publicly for everyone to watch at their convenience.

The main goal of these Zoom sessions is to help you get involved in each area. We’ll cover details not included in my keynote, update you on our progress, and give you practical advice on where and how you can contribute.

We’ve scheduled six sessions, and we invite everyone to attend. The first one will be on this Friday on participation, funding, and governance! You can find the latest schedule online at https://www.drupal.org/starshot#sessions and the core calendar in the sidebar of the Drupal core news page.

We look forward to seeing you there and working together to make Drupal Starshot a success!
 

Gemfile of dreams: the libraries we use to build Rails apps

Posted on by Michael G
From time immemorial, the Evil Martians team has worked on dozens of Ruby on Rails projects. Naturally, this involves a lot of Ruby gems. Some reflect our desire to be cutting-edge and use modern tools (or build our own!) Other gems are so flexible they’ve been used in most of our projects. Our development philosophies, programming habits, (and soul) are within this universe of Martian gems. So what would it look like if they were somehow able to converge into one gemfile—the ideal Martian Gemfile, the toolbox of the extraterrestrial Rails engineer?

Ruby 3.1.6 Released

Posted on by Michael G

Ruby 3.1.6 has been released.

Ruby 3.1 series is now in the security maintenance phase. In general, we will fix only security issues in this phase. But we have several build failure issues after the release of Ruby 3.1.5. We decided to release Ruby 3.1.6 to fix these issues.

Please check the topics below for details.

See the GitHub releases for further details.
