An optocoupler (or opto-isolator) is a component that transfer signals between circuits using light. In this guide, you’ll learn how they work and how you can use one in your own projects. Optocouplers are very useful when you need to isolate different sections of a circuit, for example in power supply circuits to transfer signals
A Solid-state relay (SSR) is an electronic switch without moving parts that use semiconductor technology to turn things on and off. In this guide, you’ll learn how they work, what they are used for, and how you can apply them in your circuits. Relays are very important in electronics because you can use them to
RGB LEDs are a type of LED that can emit a wide array of colors. In this tutorial, you’ll learn how RGB LEDs work and how to use them with Arduino or in other circuits to produce different colors.
A Light-Emitting Diode (LED) is a small component that illuminates when current flows through it. RGB LEDs operate on the same principle, but they internally contain three LEDs (Red, Green, and Blue) capable of combining to produce nearly any color output.
Using the transistor as a switch is a practical and useful skill to have. By setting up transistors in very simple circuits, you can easily control things like DC motors, lamps, buzzers, and much more. This is useful for beginners and experienced electronics enthusiasts alike. In this guide, you’ll learn the basics, the necessary components,
The Bipolar Junction Transistor (BJT) is one of the two most used types of transistors. You can use it to create audio amplifiers, switch on/off DC lamps, motors, and much more.
In this tutorial aimed at beginners, you’ll learn the basics you need to start having fun and design your own transistor circuits.
The diode bridge rectifier is a simple circuit used to convert alternating current (AC) into direct current (DC). In this guide, you’ll learn how it works, what it’s used for, and how you can build your own.
Even though you may not notice it, the diode bridge rectifier is everywhere. It’s used for transforming the AC voltage from your wall outlet into a DC voltage that your devices can use.
So when you charge your phone or laptop, or you turn on the TV, there’s often a diode bridge working its magic in the back.
A DC linear power supply is an electric circuit that converts AC voltage to a stable regulated DC voltage – without any switching or digital circuitry. This makes the circuit both simple to understand and easy to build.
In this guide, you will learn how DC linear power supplies work and how to build your own.
In this guide, you will discover what a Schottky diode is and how it can be used in electronic circuits.
Did you know that Schottky diodes, unlike other diodes, are formed by the junction of a semiconductor material with a piece of metal? That’s gives it some special properties that can come in handy.
Diodes are components that normally only let current flow in one direction. Like a regular diode, the Schottky diode allows current to flow in the forward direction when enough forward voltage is applied.
However, while a regular PN junction diode is made by connecting p-type and n-type semiconductors, the Schottky uses metals like gold, tungsten, platinum, or aluminum instead of the p-type semiconductors.
In this guide, you’ll learn exactly how a Zener diode works and how to use it in circuits.
Did you know that some of the common things you can build with Zener diodes include simple power supplies and guitar pedals?
Sounds interesting? Let’s jump in!
The rectifier diode lets you convert alternating current (AC) to direct current (DC). In this guide, you are going to learn how this component works and some of the circuits you create by using one. Diodes are one of the basic electronic components in electronics. There are many types of diodes, but the most common
A shift register is a common building block in digital electronics that is used to store and move bits, for example, to convert from serial to parallel data and vice versa.
It is basically a group of flip-flops that can store bits, and shift its stored bits sideways by one bit-position every time it is triggered. It is made using a series of D flip-flops with the output of one connected to the input of the next. Each clock pulse triggers a shift.
In this tutorial, you will learn the different types of shift registers, how they work, and how to build them using flip-flops.
The T Flip-Flop is a flip-flop that can toggle its output. Toggling means switching its output to its opposite; 1 becomes 0, and 0 becomes 1. This type of flip-flop is often used in counters and frequency dividers. In this quickstart tutorial, you will learn how it works, its truth table, and how to build
The JK Flip-Flop is a type of flip-flop that can be set, reset, and toggled. It can be used for making counters, event detectors, frequency dividers, and much more. In this tutorial, you will learn how it works, its truth table, and how to build one with logic gates. What is a JK Flip-Flop? Flip-flops
The D Flip Flop is an edge-triggered circuit that combines a pair of D latches to store one bit. It is commonly used as a basic building block in digital electronics to create counters or memory blocks such as shift registers. In this tutorial, you will learn how it works, its truth table, and how to build one with logic gates.
The D Latch is a logic circuit most frequently used for storing data in digital systems. It is based on the S-R latch, but it doesn’t have an “undefined” or “invalid” state problem. In this tutorial, you will learn how it works, its truth table, and how to build one with logic gates.
