Basic Electronics Resource Library

If you want to learn and build your own inventions with electronics, you need to learn the basics of electronics.

Without a good understanding of basic concepts such as current and voltage, it's going to be hard (or impossible) to understand how different circuits work.

But it doesn't have to be hard. Do *not* confuse basic electronics with "all electronics theory that exist". A lot of books and blogs make this mistake. And it's discouraging for beginners.

Basic electronics is easy.

This page is a library of resources to help you learn the real basics of electronics.

Kirchhoffs Law of Voltage and Current

Kirchhoffs law of current and voltage are two laws that are really useful when you are working with circuits. Knowing them will make it much easier to understand circuit diagrams, design electronics, repair electronics and everything in between. Though they might sound complicated (*), they’re not. After you’ve learned them, it’s not really something you […]

Electronics Books For the Enthusiast

Sometimes I really enjoy diving into electronics books with a freshly brewed coffee by my side. Just immersing into some interesting subject. But it is really important to not get stuck in the books. You need to get your soldering iron out and practice what you learn. Otherwise it’s no use learning it, right? There […]

PNP Transistor – How Does It Work?

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you. In my […]

How To Choose a Power Supply?

There’s some confusion going on when it comes to how to choose a power supply. So, I thought I’d clear up some doubts, and give you a simple, beginner-friendly way of choosing a power supply. Let’s start with the basics. A power supply has a voltage and a current specification: The voltage is the output […]
