EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile memory type found on most Arduino boards. It allows you to store data even when the power is disconnected, making it suitable for settings, calibration values, or other data that needs to be retained. Here’s a guide on how to use it: Understanding EEPROM Non-Volatile: Data persists even after power off. Limited Writes: EEPROM has…

Imagine trying to bake a cake by throwing ingredients together without a recipe. Chaos, right? That’s what coding without understanding syntax is like. Syntax is the set of rules that dictate how you write code in a specific programming language, much like grammar rules in English. It’s the difference between a computer understanding your instructions and spitting out errors. Why is Syntax Important? Computers…

Asynchronous JavaScript is the backbone of modern web development, allowing us to build responsive and dynamic applications. One of the key concepts to master in asynchronous programming is Promises. Understanding Promises A Promise in JavaScript represents the eventual outcome of an asynchronous operation. It’s like a placeholder for a value that will be available in the future, either resolved (successful) or rejected (failed). Creating…

Dependency injection (DI) is a fundamental concept in software engineering, particularly valuable in object-oriented programming. It promotes modularity, testability, and maintainability by decoupling the creation and management of objects within an application. This article delves into the practical implementation of DI in Java, providing a clear path to understanding and leveraging its power. Understanding Dependency Injection At its core, DI is about delegating the…
