I have to admit, I’m biased. I think LEDs are awesome. But, really, the reason I’m biased and love them so much is because they’re just so cool. I’ve found that as I replaced the ...

Every circuit has a power source, or else it won’t do much. While the actual power source can vary wildly, they all fit under the two general titles of “voltage source” or ...

Potentiometers. Pots. Trimmers. Rheostats. If you’ve done very much with electronics, you’ve heard at least a couple of these words. Maybe you’ve heard them interchangeably and ...

If we recall some basic topics in chemistry, we’ll remember that all atoms consist of neutrons, protons, and electrons, except for a normal hydrogen atom which doesn’t have a ...

One would think that, if you need a specific resistance, you would find a resistor of that resistance and you’d never have to worry about putting multiple resistors together. The ...

Before semiconductor devices existed, vacuum tubes were the only devices available for signal amplification, switching, and other applications. Though vacuum tubes are functional, ...

Multimeters are used by anyone who deals with electricity. They’re very versatile and can be used to characterize an embedded system or troubleshoot a non-functioning lightbulb in ...

We are going to have a quick discussion of the two classifications of semiconductors, which will help us understand the basics of semiconductors better.

With the amount of fully functional development boards out there, it’s possible that you won’t use a breadboard very often. However, if you spend enough time in electronics, it’s ...

Despite the fact that there are many, many buttons on an oscilloscope, if you keep things simple and ignore what you don’t need, they’re not too bad to use. Let’s go over what the ...

There are two different ways to look at phases. First, it’s when voltages are out of phase from each other, such as with 3 phase power, and second, when voltage is out of phase ...

There are two varieties of electric current that flows through our electrical or electronic devices — AC and DC. In this tutorial, we are going to discuss about DC versus AC ...

We’d like to delve more into electrons and how they are related to electricity. First, perhaps the most important thing you should understand about electrons is that they hate ...

Understanding the basics of what electricity is can really help anybody learning about electronics, circuit design, power engineering, and so on. So, let’s start with a little ...
