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 ...
Welcome to today's article on our comprehensive Raspberry Pi 4 programming guide. As we saw in the previous article, the Raspberry Pi 4 may power a single seven-segment display. In addition, we also interfaced a Raspberry Pi with 4 Seven-Segment Display Modules to display the time. However, this guide will show you how to construct a Raspberry Pi 4 crypto miner that uses very little electricity.
Cryptocurrencies have been the subject of widespread conversation for some time now. It's possible to use your computer to create them, and they can be used as currency. Because of this, the Raspberry Pi can also be used for Bitcoin mining. It's also possible to mine other cryptocurrencies. One drawback of mining is that the cost of electricity often excee ...
Hello friends, I hope you all are doing great. In today's tutorial, I will give you a detailed overview of Distance Education and How Did It Grow for The Last Years. The time when the only acceptable education involved sitting in class for hours is long gone. Society as a whole realized the irrelevance of physical presence when it comes to getting an education.
As a result, we’re seeing more and more renowned experts who gained their knowledge through distance education. How did this happen exactly? The change in the educational landscape happened due to a series of different circumstances.
In this article, we will take a look at all the societal and educational reasons that lead to the growth of distance education. With fewer students opting for ...
Demand of PCB is on the rise in recent electronics where devices are becoming more compact and composed. PCB came into spotlight a while ago and made a renowned name in the development of advance technology within few years. Recent PCBs used in many electronics allow you to get rid of most conventional ways of connecting different components on the boards. Poor fabrication and board design can scare the hell out of your customers and severely effect your overall reputation in the market. Taking proper measurements and following ideal protocols can help you save bunch of time in the early stages of a project. What company you choose for fabricating your PCB widely impacts the overall nature and quality of your project. These are many fabrications ...
GitHub’s Octoverse 2024 puts a clear number on India’s developer momentum: more than 17 million developers in India are on GitHub in 2024, up 28% year over year and GitHub projects India could become its largest developer community by 2028.That matters for Web3 because the first step isn’t becoming a blockchain person. It’s becoming the kind of engineer who can ship, explain and collaborate in public.To keep one foot in the real world while you build, pick one asset page to sanity-check basics like wallets, networks and onchain transfers. For example, checking the XRP price now and then gives you a concrete reference point for what a token is and how people talk about it, with live market data commonly available on Binance. Yi He, Binance Co-Founder, put the bigger shift simply: "Crypto is ...
Hi readers! Hopefully, you are well and exploring technology daily. Today, the topic of our discourse is the FMCW Radar Sensor Optimized for IoT Applications and Health Care Devices. You might already know about it or something new and different.
FMCW radar sensors are becoming one of the leading technologies in non-contact sensing and are very widely used nowadays in IoT and healthcare devices. In general, they have more accuracy, lower power consumption, and good performance on different surfaces. Hence, they can be highly versatile by emitting a continuous wave signal with frequency modulation, capable of detecting motions, measuring distance, and monitoring the presence of people with exceptional accuracy. This non-contact capability is an important feature for applications wher ...
Hi readers! I hope you are doing well and exploring something new. When power collides with simplicity, and toughness doesn't require sacrifice, welcome to the PETG universe, the 3D printing material changing the game. Today, we will discuss PETG Filament.
In the increasingly vast 3D printing universe, selecting the correct filament can be the difference between a perfect print and a mind-bending failure. Make your move, PETG (Polyethylene Terephthalate Glycol-modified), the new kid in 3D printing that mixes toughness, flexibility, and simplicity better than all others. Many praise PETG for being an excellent middle-ground between gentle-but-fragile PLA and tough-but-unstable ABS.
What pet owners like most about PETG is its special power to balance mechanical strength with superior print ...
Hello Mentees!, I hope you have a productive day. Welcome to The Engineering Projects. In the previous lecture, we discussed the XOR Logic Gate and designed its circuit using basic logic gates i.e. AND, OR and NOT. Today, I am going to explain another Logic Gate named XNOR Gate in detail.We are going to discuss these concepts in today's lecture:
What are Exclusive NOR Gates
Experimental Proof in Proteus ISIS.
How Truth Table of Exclusive NOR Gate is designed.
How is its Timing Diagram?
Circuit of Exclusive NOR Gate in Proteus Simulation
Applications of Exclusive NOR Gates
XNOR Gate
The exclusive NOR Gate(also called XNOR Gate) simply inverts the output of the XOR Gate(we discussed in the last lecture).So, if we simply place a NOT Gate in front of the XOR Gate, we wi ...
Hello friends, I hope you all are having fun. In today's tutorial, we will create our First Web Application in ASP.NET Core. It's our 2nd tutorial in ASP.NET Core series and in our previous tutorial, we have had a detailed Introduction to ASP.NET Core.
We have also installed Microsoft Visual Studio Community Edition 2019 in our previous tutorial and today we will create our first web application in it. After creating this web application, we will also have a look at its files and will understand the contents. So, let's create our First Web Application in ASP.NET Core:
Creating Web Application in ASP.NET Core
First of all, start your Visual Studio which we have installed in previous tutorial.
A pop up window will open up, where you can open yo ...
