A resistive soil moisture sensor is a widely used, simple, and affordable way of estimating the amount of water in the soil. In this tutorial, you will learn how to interface a resistive soil moisture sensor with an Arduino UNO microcontroller. You will learn about the parts and components of the sensor, how to calibrate […]
On this week’s episode of the podcast, freeCodeCamp founder Quincy Larson interviews Joe Hill. He’s a software engineer who works on a data platform for NASA. Joe taught himself programming for 4 years while working as a janitor. As the single father of two Autistic boys, he first used his programming skills to build an […]
Building something from scratch using just PHP, MySQL, JavaScript, HTML, and CSS is one of the best ways to level up your skills and gain a real understanding of full-stack development. We just published a course on the freeCodeCamp.org YouTube channel that will teach you how to build a full stack Google Calendar-style app. If […]
If your app runs in production, you’ll need to know when it breaks. Preferably before your users tell you. That’s where application monitoring tools (APM) come in. They show you what’s working, what’s slow, and what’s failing, all in one place. Here are five of the best tools developers use today. I’ll walk you through […]
Most people know how to set goals. And many understand that developing good habits is key to reaching those goals. Yet, despite this knowledge, it’s still easy to feel stuck – or worse, in motion without direction. We chase productivity without asking a deeper question: Are my actions actually moving me toward who I want […]
JavaScript is an asynchronous programming language, which means it can handle multiple operations at the same time without blocking the main thread. When working with asynchronous operations like API calls, file reading, or database queries, you have two main approaches: Promises and Async/Await. In this article, you will learn the differences between these two approaches, […]
In today’s fast-paced industrial environments—construction sites, hospitals, manufacturing plants, and beyond—losing equipment isn’t just an inconvenience; it’s a full-scale budget sink. Whether it’s a misplaced handheld scanner, a buried set of power tools, or a vital medical device, each incident has cost implications that ripple far beyond the price tag. In this post, we’ll break […]
Modern mobile applications are far from static, single-view experiences. Instead, they are dynamic, multi-faceted environments where users seamlessly transition between different features, content, and functionalities. Because of this inherent complexity, you’ll need to set up robust routing as well as a well-designed multi-screen architecture. In this tutorial, you’ll learn about Flutter’s fundamental navigation systems: Imperative […]
Transformers have changed the game in machine learning. From powering chatbots and search engines to enabling machine translation and image generation, they’re at the core of today’s most impressive AI models. But the field moves fast. New techniques and refinements are constantly improving how Transformers perform. Understanding these changes is key if you want to […]
