Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
The WebM video format has its set of limitations. It can be used on some platforms, but is incompatible with the most popularly used multimedia software. With the masses spending more time in watching videos on their mobile devices, having an incompatible video format like WebM doesn’t make much sense. Whether you are a professional, a business or spend a lot of time watching videos, you would want to convert WebM to MP4. And you can achieve this easily and quickly using the Movavi video converter.
You will often come across a number of online tools that claim to offer free video conversion. But all those providers come with a hidden caveat. No one can afford to run a website for free and offer free services at the same time. So your video files ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to use switch Statement in C# and its our 9th tutorial in C# series. In our previous tutorial, we have seen IF Loop in C# and this switch statement is also a loop but works slightly different than IF loop and it totally depends on your application, which one you want to use.
First we will have a look at How to use switch statement in C# and after that we will also study goto statement, because switch and goto statements are normally used together. So, let's get started with it:
How to use switch Statement in C#
Switch Statement is a loop in C# which takes a variable as a condition, and then creates its different cases and we can deal each case se ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to 2N3772. I have already shared basic knowledge about different IC's and transistors in my previous tutorials e.g. Introduction to IRF540, BC547, MMBD914, LM339, LM224 and LM386. You must have alook at these tutorials before going into the details of this tutorials. It will be quite helpful in the better understanding of this article. 2N-3772 is basically a type of central semiconductor. It is basically a Negative Positive Negative (NPN) semiconductor. This semiconductor is designed by the process named as epitiaxial process. The main purpose behind its designing is to provide the high power based amplification proce ...
Hey geeks, welcome to the next tutorial about MATLAB software and language. In this series, we have been working on MATLAB with the basic information and in the previous lecture, we worked deeply with the workspace window and learned about the functions and variables that are commonly used when we are dealing with the data in the command prompt. In the present lecture, we are dealing with the data types in MATLAB. This is related to the command prompt window but the reason why I have arranged this lecture after the workspace practice is, there will be different steps where the usage of the workspace will be included. Other details will be cleared when you will take this lecture yet, have a look at the list of content that will be included in this tutorial:

Hello guys, in the last post I have explained the basics of inverters along with its types and also the inverters topology in other words working of inverters. Now in this post I am gonna explain the major components required for making an inverter. This post is not giving you any technical knowledge about inverter but to workout with inverters its necessary to go through its basic components.
I have divided this tutorial into four parts which are shown below. This is a step by step guide to design and build an inverter and ...
Believing in the essence of timers in ladder logic programming, we come today with a new tutorial in which we are going to show you all about timers, the types of timers, what’s inside timers’ block of parameters, variables, and bits. In addition, techniques for using timers will be explored, and for sure, we are going to practice what we learn using the simulator. So let’s get started with our tutorial.
Timers in ladder logic programming
Guys, this is not the first time we’ve talked about timers. However, this time we are going to look into timers deeply and use the glasses of practical approach. So figure 1 shows the most important types of timers in ladder logic from left to right: the on-delay, off-delay, and retentive timers. There are differences in functionality. However, they all ...
Hello Learner! I hope you are doing great. Welcome to another tutorial at The Engineering Projects. This blog is the part of series we have stated about the Digital Logic Circuits. Previous to this, we learned Implementation of SK Flip Flops in Proteus. at the present day, we'll seek the knowledge about the following points:
What are Flip Flops?
What are JK Flip Flops?
How can we record the Truth Table of JK Flip Flops?
What is the Procedure to Construct the circuit of JK Flip Flop through Logic Gates and IC circuit?
Moreover, we'll also have some useful bits of Information in Did you know Sections. Let' see the explanation of the concepts given above.
Flip Flops
The Flip Flops are the building blocks of many of the Electronic Circuits. ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to give you a detailed overview of Controllers in ASP.NET MVC. It's the fourth article in ASP Web App Series. In our Previous tutorial, we have had a look at Views in ASP.NET MVC and in that tutorial, we have mentioned this Controller a lot and today we are gonna discuss it in detail.
Controllers acts as a messenger in ASP.NET MVC Web App, it takes message or data from place to another. I have also shared a video at the end of this tutorial and I would suggest you to watch it once to get better understanding of controllers. So, let's get started with Controllers in ASP.NET MVC:
Controllers in ASP.NET MVC
Controller is the back bone of any ASP.NET MVC Web App as it ac ...
