Hello friends. In this lecture, we are going to have a look at the different kinds of MATLAB data types.
As we have already seen in previous lectures, MATLAB stands for MATrix LABoratory and allows us to store numbers in the form of matrices.
Elements of a matrix are entered row-wise, and consecutive row elements can be separated by a space or a comma, while the rows themselves are separated by semicolons. The entire matrix is supposed to be inside square brackets.
Note: round brackets are used for input of an argument to a function.
A = [1,2,3; 4,5,6; 7,8,9];
An individual element of a matrix can also be called using ‘indexing’ or ‘subscripting’. For example, A(1,2) refers to the element in the first row and second column.
A larger matrix can al ...
This is the third tutorial in our Raspberry Pi programming course. In the previous chapter, we learned how to install Raspbian on our Raspberry Pi mini-computer. In this chapter, we'll learn how to use a VNC server to remotely control and see its desktop from our computer.
What is VNC?
Computing over a network is known as "virtual network computing," or "VNC." To remotely control another computer, you can use this screen-sharing technology, which works on all major operating systems. As a result, a remote user can interact with a computer's display (screen, keyboard, and mouse) as if they were sitting right in front of it.
VNC takes advantage of the client/server concept. Rather than installing a VNC s ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to print from a Raspberry pi. We also discussed some libraries to create a print server in our raspberry pi. We will learn how to take screenshots on Raspberry Pi using a few different methods in this lesson. We will also look at how to take snapshots on our Raspberry Pi using SSH remotely.
Why should you read this article?
This article will assist you when working with projects that require snapshots for documenting your work, sharing, or generating tutorials.
So, let us begin.
Screenshots are said to be the essential items on the internet today. And if you have seen these screenshots in tutorial videos or even used them in regular commu ...
Hi Friends! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll walk you through Edge Computing vs Cloud Computing.
Cloud computing has been around for many years while edge computing, on the other hand, has just become the prime topic of mainstream organizations. But what is the key difference between both edge computing and cloud computing, how do they work, can we implement both in the IT model of any business? These are the main questions that arise every time someone tries to get a hold of these terms. Don’t worry. We’ll discuss them in detail so you know when to pick a cloud model and when to choose edge computing.
Keep reading.
Edge Computing vs Cloud Computing
Before we go further to describe the comparison between edge and cloud, know that, both ...
Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4. Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4.
DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits.
Project Description
Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD.Let's have a look at the components required for this project:
Components ...
Hello Folks! Glad to have you on board. Thank you for clicking this read. In this post today I’ll walk you through What is Cloud Computing?
Cloud computing is not a buzzword anymore. Even though most companies are familiar with this term, they don’t know what it does and how it works. If you’re one of them, this read is for you. In simple terms, cloud computing allows you to use computer system resources over the internet. This means you can manage your data remotely over the internet from anywhere in the world. We’ll touch this further in our article.
I suggest you read this post all the way through as I’ll cover what is cloud computing, how does it work, the types of cloud computing, the advantages of cloud computing, and the future of cloud computing.
Let’s get started.
What is Cloud ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
Hello, Students here I am present to cover an article on a series of Electronic devices and circuit theory. The foremost article of this series is Ideal diode vs practical diode. I try to elaborate on basic to modern theory related to the diode. This component act as fundamental to many important circuit devices such as rectifiers, transformers, etc. The question which we cover in this article are;
What is a diode?
How a diode is formed? Which methodology manufacturer utilized while the formation of the diode?
What is the concept of doping and PN junction in diode theory?
How does a Diode work?
What type of biasing allows a diode to conduct? Under which situation of biasing diode offers a restriction while conducting?
Upon which cha ...
Hello readers, I hope you all are doing great.
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT.
Project Overview
In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32.
Fig. 1
To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD).
We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to displa ...
Hello friends, I hope you all are having fun. Welcome to the 10th tutorial of our Raspberry Pi programming course. In the last chapter,
