Digital Electronics: Binary Basics

Digital electronic circuits rely on the binary number system. Thus, before you can understand the details of how digital circuits work, you need to understand how the binary numbering system works. [more…]

Digital Electronics: Logical Operations

One of the things that makes binary so useful in electronics is that it’s very efficient at handling special operations called logical operations. Logical operations [more…]

Digital Electronics: How to Use Windows Calculator for Binary Conversions

In the course of working digital electronics projects, it’s unlikely that you will have to convert a number between binary and decimal. If you do find that you need to convert binary numbers to decimal [more…]

Electronics Schematics: Commonly Used Symbols and Labels

Simple electronic circuits can have as little as two components. Most electronic circuits will have additional components. There are hundreds of different types of electronic components, and each has its [more…]

Electronics: Introduction to Infrared Light

Many electronic circuits detect the invisible light that’s commonly called infrared. Infrared light is light whose frequency is just below the range of visible red light. Specifically, infrared is light [more…]

10 Ways to Explore the World of Electronics

Ready to build on a newfound knowledge of electronics? Want to expand your horizons and create programmable electronics projects? The following list provides you with a list of ideas for enhancing your [more…]

What Is Electronics?

Electrical systems use electric current to power things such as light bulbs and kitchen appliances. Electronic systems take this a step further. When you turn on a light in your home, you’re connecting [more…]

What Is Electricity?

The term electricity is ambiguous, often contradictory, and can lead to confusion, even among scientists and teachers. Generally speaking, electricity has to do with how certain types of particles in nature [more…]

The Role of Atoms in Electronics

Atoms are the basic building blocks of everything in the universe, whether natural or manmade. They’re so tiny that you’d find millions of them in a single speck of dust. [more…]

The Roles of Protons and Electrons

Electric charge is a property of certain particles, such as electrons, protons, and quarks (yes, quarks) that describes how they interact with each other. There are two different types of electric charge [more…]

Use Circuits to Ensure Electrons Arrive at Their Destination

Electric current doesn’t flow just anywhere. (If it did, you’d be getting shocked all the time.) Electrons flow only if you provide a closed conductive path, known as an [more…]

Tools Needed for Electronics Projects

To complete many experiments and projects, you'll need a few tools that may cost you $100 to $250 total, depending on where you shop. Besides the essential listed here, you'll need to have a calculator [more…]
