Overview of the Arduino Electronics Platform Arduino, a groundbreaking technology in the amateur electronics ecosystem, has revolutionized the way people learn and interact with electronics. Unlike traditional electronics studies, Arduino brought fun and ease to the learning process, making it accessible to beginners. This Italian-born marvel has created an entire industry and movement, known as the makers movement. By being a completely open-source platform, Arduino has gained immense popularity, allowing individuals and companies to build their own Arduino clones and contribute to its ever-growing ecosystem....

In my electronics tutorials, I often use a 9V battery to power the circuits. While it’s simple and easily accessible, it’s not the most efficient option. The battery tends to drain over time, resulting in a voltage lower than the advertised 9V. To overcome this issue and enhance the performance of your circuits, I recommend using a Breadboard Power Supply Module. This module allows you to input power from various sources, including a battery, a 12V adapter, or any other compatible source....

The 1602 LCD display is a widely used alphanumeric display that consists of two lines, each capable of displaying 16 characters. Its versatility makes it suitable for various applications, including vending machines and train stations. While it is commonly included in Arduino kits, the instructions provided here can be applied to any LCD display that has a 16-pin interface compatible with the Hitachi HD44780 LCD controller. To control the display, the LiquidCrystal Arduino library emulates the Hitachi HD44780 LCD controller....

Are you new to electronics prototyping? Do you want to quickly try out and test different circuit configurations without soldering? Look no further - breadboards are the perfect solution for you! What is a Breadboard? A breadboard is a small, white box-like structure that allows you to easily create and test electrical connections. It consists of multiple sets of interconnected elements on both sides. Each set typically contains 5 interconnected holes, making it easy to connect components....

In the world of electronics, there are two major divisions: analog and digital. Understanding the difference between these two is essential in grasping the fundamentals of electronic systems. Analog refers to the representation of real-world quantities and values, which can vary continuously. Everything in nature, such as temperature, light, sound, and more, can be measured in an infinite number of values and precision. Analog signals are continuous and represent these natural variations....

Current is a crucial concept in electronics as it refers to the flow of electrons between two points with varying voltage. It is typically measured in ampere (A) and can be categorized into two types: alternating current (AC) and direct current (DC). Direct current (DC) is characterized by the flow of electrons in one direction and is commonly produced by batteries. On the other hand, alternating current (AC) undergoes periodic changes in direction and is the type of current supplied by the electrical grid, enabling us to power our homes through wall sockets....

Johnny Five is a fantastic library that allows developers to communicate with electronic devices using JavaScript. While devices like Arduino are typically programmed in the Arduino Language, Johnny Five enables us to interface with Arduino using JavaScript, particularly in Node.js. Setting up your Arduino to work with Johnny Five To get started, follow these steps: Download the Arduino IDE from http://arduino.cc/en/main/software. Connect your Arduino board to a USB port on your computer....

In the world of electronics, different terms are often used to refer to the same concept. It’s important to grasp these terms to build a solid foundation in electronics. One commonly mentioned concept is the negative pole of the battery, which can be referred to as “-”, “0V”, the ground, “GND”, or “Vss”. These terms all indicate the same thing - the negative pole of the battery that is at 0V....

Voltage is a fundamental concept in electronics that refers to the electric potential that allows electrons to flow from an area of higher voltage to an area of lower voltage. It is measured in volts (V). The higher the voltage, the greater the flow of electrons in a circuit, which is known as current. To better understand voltage, let’s consider a simple example. Imagine a circuit with an LED light. If you power this circuit with a 1....

In my Electronics tutorial series, I use a set of tools that I have acquired over time. If you’re looking to get started with the experiments I do, I can provide some recommendations on what to buy. When it comes to Arduino, I highly recommend purchasing original Arduino parts to support the project and its ecosystem. However, when starting out, buying individual components can be costly. That’s why I suggest looking for kits that come with a variety of components all at once....
