Creating a voltage divider is a common application of resistors in electronics projects. By placing two resistors in series in a circuit, it is possible to achieve a desired voltage drop. Let’s explore how this works and how to calculate the voltage using the formula V * (R2 / (R1 + R2)). To begin, visualize the circuit setup with two resistors connected in series as shown in the image below....
In this blog post, I will guide you through the process of building an LED dimmer using a potentiometer. It’s a simple and fun electronic project that you can easily do at home. To start off, you will need a few components: A 10kΩ potentiometer - This will allow you to control the brightness of the LED. A 5mm LED - You can choose any color you like. A breadboard - This is where you will assemble your components....
A digital multimeter is an essential tool for anyone starting out in electronics. With a wide range of functions built into a single device, it allows you to measure voltage, current, resistance, capacity, frequency, and more. In this article, we will focus on how to measure voltage, current, and resistance using a multimeter. Selecting the Right Multimeter When it comes to multimeters, there are various options available in the market. While you can find very cheap ones for around $10, investing in a quality multimeter for less than $30 is a better choice....
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....
In this blog post, we will guide you through creating your first circuit using simple components like a 9V battery, a 470 ohm resistor, and a LED. We’ll also introduce you to a useful online tool called Tinkercad for circuit simulation. So let’s get started! If you’d like to follow along and try out the circuit yourself, we highly recommend getting a starter kit like the “ELEGOO UNO R3 Project Most Complete Starter Kit” from Elegoo, which you can find on Amazon....
Recently, I made the switch from the deprecated markdown renderer, Blackfriday, to the default Hugo markdown renderer, Goldmark. While this transition had been long overdue, it came with a drawback - all the embedded HTML in my markdown files ceased to work. However, I found a solution to this issue by enabling a specific option in my Hugo configuration file, whether it be config.yaml or config.toml. Here’s how to do it:...
In today’s fast-paced, interconnected world, I find comfort in being part of a unique community. This niche consists of individuals who utilize digital devices such as desktop computers, laptops, smartphones, or tablets to create and distribute value within the digital network. My role in this ecosystem is to assist software developers in honing their skills through informative blog posts and engaging online courses. However, it’s disheartening that in my everyday life, I rarely encounter others who share my passion....
In today’s fast-paced and information-driven world, it’s easy to get overwhelmed and distracted by the constant flow of data and opinions. That’s where selective ignorance comes into play, allowing you to filter out the irrelevant noise and focus on what truly matters. Selective ignorance can be defined as the deliberate act of ignoring distracting, irrelevant, or unnecessary information. While Tim Ferriss introduced a similar concept in his book “The 4-Hour Work Week” called the “information diet,” selective ignorance goes a step further....
