Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you an Introduction to 2N2222. It is the most commonly used Negative-Positive-Negative (NPN) Bipolar Junction Transistor (BJT) available in the market now a days. 2N2222 can be used for different purposes e.g. switching and amplification of analog signals. I hope you have enjoyed the previous post on Introduction to ULN2003.
The major functional area of 2N2222 is enclosed in TO-18 package. Due to the low cost and small size it is the most commonly used transistor. One of its key features is its ability to handle the high values of currents as compared to the other similar small transistors. Normally it is capable of switching a load current of 800mA whic ...
Hello friends, I hope you are are doing well. In today's tutorial, I am going to discuss Bachelor of Science. The Bachelor of Science is a three to four years undergraduate academic degree offered at universities worldwide. It enables the students to develop his or her interests in a science subjects by choosing major. However, the main aim of Bachelor of Science degree is to develop and enhance student’s mathematical, analytical, problem-solving skills. Today, in this article, you will get to know the detail of popular BSc programs of 2021, their duration, benefits and career opportunities.
Bachelor of Sciences
Students have the option to choose their major subject with other science subjects according to their interest. Research abilities are mos ...

Hello friends, I hope you all are doing great. In today's tutorial, I am going to give you a detailed introduction to the C++ Programming language. In cross-platform programming languages, C++ is the most popular that can be used to work on low and high-level applications. Bjarne Stroustrup was the founder of C++. He modified C language to develop C++ language. Control over system resources and memory can be attained by using C++. In 2011, 2014, and 2017 it was modified to C++11, C++14, and C++17. C++ is a middle-level language. It is advantageous to both programming languages low-level (drivers, kernels) and higher-level applications (games, GUI, desktop apps etc.).
Uses of C++
C++ is one of the world's most famous programming languages. It is u ...
Hi Guys! I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to 1n4004.The 1n4004 is a diode that allows the current to flow in one direction only. It blocks the flow of current in the opposite direction. It comes with two terminals called anode and cathode and current always flows from the anode terminal to the cathode terminal. This device comes with a reverse peak voltage of around 400V and it can support loads under 1A.
I’d recommend reading the Introduction to 1n4007 that I’ve uploaded previously. This diode is almost similar to the device 1n4004 that I’m going to stretch in this post.
I suggest you buckle up as I’ll discuss the complete introduction to 1n4004 covering datasheet, pinout, features, equivalents, and applicati ...
Hello friends, i hope you people are fine and enjoying. Proceeding to my previous tutorial, in which i explained Brushless DC motor in detail. Now in this tutorial i am going to explain in detail the second type of DC motor which is Brushed DC motor. In this tutorial, we will see what is in fact a Brushed DC motor, how it works and what are the advantages and practical application of this type of motor on some other type of motors.
Brushed DC motors are also known as commutated DC motors. Reason is that these motors contain commutator and carbon brushes for rotor excitation. I will explain all these terminologies in detail, later in tutorial. These are the most important type of motors designed to run directly on DC power supply. These were the ve ...
The choice of operating system for a virtual private server depends on the needs of a particular company. But if you are looking for a reliable, efficient, and flexible solution to host your web projects, in most cases it will be Windows VPS. In this article, we'll analyze why many people prefer Microsoft solutions, and what benefits and limitations you can expect if you decide to buy a Windows VPS
.
What is a Windows VPS and what it is used for?
Windows VPS is a virtual private server that uses Windows Server as the underlying operating system. Windows VPS functions effectively as a cloud server with elastic scalability. This means that you get a dedicated server resource that you can use as you see fit, and you can easily add resources as ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at What is Hall Effect Sensor and how to use for measurement of electromagnetism. As we can easily find the value of current flowing through any elements, by using ammeter, and galvanometer. But it is very challenging for us to measure the strength of the magnetic field. If we ask someone to find the magnetism and tell us its value. He will not have an answer to this question.
In 1879 an American physicist invented the hall effect sensor for the measurements of the electromagnetism. After the invention of Hall effect sensor, almost twenty years scientists were thinking about how we can use the Hall effect practically. With the simplification of the semiconduct ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to Ethereum accounts. I have given you an introduction to blockchain in my previous tutorials, so let’s get started on the essentials of this technology. I am going to start with accounts.
Ethereum Accounts
An account is an important component of the Ethereum system.
It is the main building block and has a balance in ether (ETH) (Ethereum currency).
An account is capable of sending transactions on the Ethereum network.
The interactions between different accounts create transactions that are stored in the distributed database.
Each transaction involves the sender account, receiver account and contract account.
An account can be controlled b ...
Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B20, DHT11, BMP280 etc. We will first discuss the basics of this Internal Temperature Sensor and then will design a code to monitor the change in temperature by changing the frequency of the ESP32 CPU.
