The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet.
To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers.
Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications.
Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR s ...
Hi Friends! Hope you’re well today. In this post, I’ll walk you through What is Edge Computing?
Edge computing is the extension of cloud computing. Cloud computing is used for data storage, data management, and data processing. While Edge Computing does serve the same purpose with one difference: edge processing is carried out near the edge of the network which means data is processed near the location where it’s produced instead of relying on the remote location of the cloud server.
Confused?
Don’t be.
We’ll touch on this further in this article.
Curious to know more about what is edge computing, the difference between edge computing and cloud computing, benefits, and applications?

Hi guys! Hope you’re well today. In this post today, I’ll cover What is Industrial IoT (Internet of Things?)
IIoT is now a talk of mainstream conversation. This term has blown up in the past couple of years. Before we move further to describe IIoT, it is evident that industries are no longer dependent on the traditional production processes that happened to be costly and guaranteed no optimal results. Now companies are willing to incorporate automation in manufacturing and production processes. Smart systems, no doubt, are dangerous for the traditional labor workforce, but on the other hand, they create more opportunities for the people equipped with the latest business trends.
Curious to know more about Industrial IoT, how does it work, the difference between IoT and IIoT, examples of II ...
Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Hi friends, today we are going to explore mathematical computations in ladder logic. Like in any programing language you should find logic and mathematic computations, here in PLC programming you often need to process the input data that is collected from reading analog devices like temperature, level, flow et cetera. Then you need to run some calculations on this data to derive some other variables for deciding to run or stop some device or even to determine analog output to output to analog device i.e. valve or actuators. In the following sections, we are going to explore the mathematical functions and their input operators and outputs as well. Then we will show how to utilize such functions in ladder logic with simple examples and as usual enjoy practicing them thanks to the PLC simula ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project which is an Up-Down counter. Most of us who have an electronics background or studied digital electronics must know the counter. Counter is a simple device which counts numbers. As per the digital electronics, there are two types of counter, the Up counter which counts in increasing order and another is Down counter which counts in decreasing order. And every counter has a reset limit, on which the counter resets to its initial value and starts the counting again. The limit of every counter depends on the bits of counter. For example, we have a 8 bit Up counter which means it will count upto 255 and afterwards it will reset and will start agai ...
Hello friends, I hope you all are doing great. Today, I am going to start a new tutorial series on Raspberry Pi 4. It's our first lecture today, so I will explain the basics of Raspberry Pi boards. In this tutorial series, I will teach you each and everything about Raspberry Pi and its programming. I have designed this guide for beginners, so we will start from the very basics and will slowly move toward complex concepts. Python programming language is used in Raspberry Pi boards, so we will study Python as well. So, we will learn both programming and hardware circuit designing in this tutorial series. Let's first have a look at What is Raspberry Pi?

Hi friends and hope you are all very well. Today, we are going to deal with one of the most important and common problems that would be there in everyday tasks in industry and its solution. The problem is the safety of equipment and operators by preventing the machine from running under specific conditions for realizing the safety of equipment and human as well. Not only does it fulfill safety but also it is for performing the designed sequence of operation. If there is a problem, then it should be the solution for it. the solution is what so-called “Interlock”. So, what is interlock? And why do we need it? And how we can design a good interlock? Well! We may find such concerns exist in two aspects which are safety and operation sequence. In the f ...
Hello geeks, welcome to our new project. Here, we are going to make a very useful project which we can use for ourselves or we can use this as a product as well on an industry level.
In this project, we are going to make a water level indicator. We all know it is one of the most essential products because there are many water tanks in every house or office, and most of them are not easily accessible to check the level of water in it and I think most of us faced the problem such as shortage of water as we do not have anything to monitor the exact amount of water available in the tank and this causes many problems on our daily lives.
Software to install
As we are going to make this project in the simulation first, for that, we will use the Proteus ...
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 ...
