Switches are literally everywhere! They are in many of the devices we use on a daily basis and a most basic part of just about every electronics project! So in this electronics basics tutorial we’re going to cover the different types of switches and what the applications that they are used for. At its most […]
Batteries are everywhere in our lives. Not only in the products we buy, but in our electronics projects! It’s not always clear when we should use which time, or what even makes one type of battery different from another. In this tutorial we’re going to cover the different types of batteries and talk about some […]
In this tutorial, we’re going to learn how rotary encoders work! Rotary encoders (also shaft encoders) are a fantastic way to dial in a position, or determine the position of a shaft. This could be the position of a knob you are turning, or it could be an encoder connected to a stepper motor to […]
In this tutorial, it’s going to be all about rectifiers! We’re going to learn the basics of their operation, and then we’re going to build a bridge rectifier circuit out of four diodes that can be used in your projects to convert AC to DC. In a previous tutorial we talked about diodes and how […]
In this tutorial, we’re going to answer your burning question: “What is a capacitor?”! Capacitors are one of the most basic components used in electronics and most all of our projects incorporate a capacitor in some form or another. Understanding how they work and how to use them is a skill most beginners should learn. […]
In this tutorial we’re going to answer the fundamental question that you’ve all been asking recently, “What is a diode?” A diode is a fundamental component that is at the very basics of many electronics projects. Unlike some of the passive components we’ve talked about recently (like resistors), a diode is a semiconductor. And as […]
You’ve probably seen resistors in most of the projects we do here at The Geek Pub, and wondered to yourself “What is resistance?”. Well today we’re going to do a tutorial on resistors and learn exactly what resistance is and how it works! How Resistance Works In our voltage tutorial we discussed how voltage seems […]
In our first tutorial about basic electricity, you learned that current is just the flow of electrons in a wire. You learned about current and that its unit of measurement Amps refers to how many electrons are flowing past a certain point per second. In this tutorial we’re going to answer the questions you’ve all […]
This is new set of tutorials on the basics of electricity. I am often asked some of these questions, and I thought it would a great idea to have a place to share and send people to for the answers. Today we’re going to answer the question “What is current?” It’s a confusing topic and […]
