Hello geeks, welcome to our new project. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well.
So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages.
Software to install
We will make this project in the simulation, as it is a good practice to make any project in the simulation fir ...
Hi friends and hope you are doing very well. Today we would like to take one tutorial which is very essential in the industry which is analog input processing for handling analog measurements of physical signals like temperature, humidity, pressure, distance, flow and level of liquids, etc. Typically, sensors produce two types of analog signals to represent the equivalent measured signal which is current and voltage signals. The currently produced signals would be within the range of 4-20 mAwhile voltage signals are in the range of 0-10 v. because, that output signals represent physical signals, the limits of output signals are 0 to 10 v for voltage based sensors and 4 to 20 mA for current-based sensors, these values should be scaled to represent ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

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?
Keep reading.

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 ...
In this article, we will discuss the introduction to organic chemistry in which we will study organic compounds, classification of organic compounds, types of formulas, use, significances, general and covalent bond characteristics of organic compounds, and homologous series and his characteristics. 9 out of 10 takes the organic chemistry too tough but I explained it easily and simply to you. This article is for beginners and clears many topics.
Introduction to organic chemistry
Old Definition:
“The chemistry of compounds obtained from living things.”
Vital force theory
Swedish Chemist Jacob Berzelius put forward this theory in the 19th century.
State
“ Organic compounds could not be synthesized in the laboratory due to the influence of a mysterious force called vital force, which occur ...
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?
What is Raspberry Pi?
Raspberry Pi is a series of Single Board Computer, developed by the Raspberry Pi Foundation in England, to teach co ...
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython.
Introduction
Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a ...
Hello friends, in the previous tutorial we learned about ions and now I am coming up with a new article Molecular ion. In this article, we will discuss the formation of molecular ions. When we discuss molecular ions many types of questions arise in our minds. I hope after reading this article you can answer these questions which are given below:
What are molecular ions?
How many types of molecular ions?
How molecular ions are formed?
Why is NH4 + not a molecular ion? Give a reason.
Which type of molecular ions structure exists etc.?
Which example is suitable for molecular ions or not?
