Welcome to another C Tutorial! This time we’re going to delve into arrays in C programming.
Arrays are important features in many programs. They enable you to store several items of related information in a convenient way. They’re good for collecting data, pin numbers (i.e. for Arduino), storing variables and more.
Let’s start by talking about what an array in C actually is.

Since the early 1990’s the servo motor has been finding its way into robotics projects more and more often.
But what is a servo motor?
How do servo motors work?
This introductory tutorial on servo motors will answer these questions.
If you’re into electronics, you may have heard the word servo or servo motor thrown around.
If you’re a robot builder or into model planes, boats, and cars, there’s a chance you know something about servo motors.
The benefits of using servos for robotics and other things are many. They’re small, light, relatively cheap, and easy to use. And most of them sport a design that makes mounting a snap.
Let’s dive into some detail on how servo motors work.

What is voltage?
If you live in the U.S., you know that a typical power outlet puts out 120 V.
You may know that the battery in your car is 12 V.
If you’re an Arduino enthusiast, you know probably know that the Uno has 5 V and 3.3 V outputs.
But what does all this mean?
What are volts, anyway?

Do an online search for the word filter and you’ll get a ton of results ranging from car parts to coffee. This post, however, will focus on electrical filters.
Even if we narrow our search down to the term electrical filter, we’re still going to get a ton of results. After all, entire books have been written on electrical filters (I should know, I own one).
That’s because even in the realm of just electrical filters there are many different types.
We have passive and active filters. Digital and analog filters. Filters bearing the name of their creator like the Butterworth filter, Bessel filter, and Chebyshev filter (don’t ask me how to pronounce that). And there’s more.

What is DNS and how does it work?
This post will take a bird’s eye view of DNS and answer that question.
A while ago, I wrote a similar article about how DHCP works.
In it, I made some assumptions about you, the reader. Here I’m going to make the same assumptions and repeat them.

Why exploding capacitors? Why desecrate such a useful, universal electronic component?
I recently did a post on electrical safety. In it, there was a section on capacitors where I mentioned that small, low voltage capacitors can be dangerous because they can explode if the conditions are right.
This got me thinking what if I were to produce a video of this phenomenon to demonstrate it? The idea also sounded like a load of fun, so I went ahead with it.
