Hey guys! I aspire you a prosperous life filled with joy and happiness. Today, I am going to uncover the details on the Introduction to 2n4402. It is basically a PNP (Positive-Negative-Positive) silicon transistor where N doped layer lies between the two P doped layer. It consists of three terminals i.e. emitter, base, collector. Here N represents the base of the transistor and two P layers represents the emitter and collector respectively. I'm going to cover all aspects related to this transistor. Let's hop on the board and dive in the details of this silicon transistor.
Introduction to 2n4402
2n4402 is a bipolar silicon transistor, where one layer of N doped semiconductor is sand-witched between the two layers of P doped semiconductor.
It w ...

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Create a New Model in ASP.NET MVC. It's 5th tutorial in ASP MVC series. We have already seen the basic concept of Model in ASP.NET MVC in our second tutorial. Models are used to communicate data from SQL Database to respective Controllers, which is then displayed by the Views to the user.
When you are designing some professional website then it happens a lot that you need to place different data in your databases, normally this data is coming from users. So, in such cases you have to create new models and then assign respective controllers to them. So, today we will see How to do the first ...
Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server.
In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service.
IFTTT is used as a third-party web service to integrate Google sheets with ESP32.
Fig. 1
Creating an IFTTT Account for Integrating ESP32 with Google Sheets
We are going to create an applet (on the IFTTT server) that is responsible to integrate the Webhooks and Google Sheets services.
While operating with the IFTTT server there are some services/utilities that we are going to deal with like Applets an ...
Traditional concrete can develop cracks through recurring freeze-thaw cycles over time. Cracks expand as it freezes, potentially letting water seep in further pulling it apart. Just as concrete deteriorates, steel structures do too due to inevitable corrosion. The rusted steel eventually wears the entire structure, threatening a crash if not inspected by a safety engineer. Innovations in building materials are rapidly disarming hazards posed by old materials—a British steel company patented a new form of colour-coated steel, galvanized steel, being used as additional protection against adverse environmental factors. Read more here.
Researchers have pondered whether materials could be made as such to bounce back from harsh conditions and vulnerab ...
Hi, my friends and welcome back. I am happy to meet you again with a new tutorial of our PLC ladder logic programming series tutorials. Today we will complete what we started the last tutorial on the Elevator control project. We have a bunch of duties to complete together today. So let’s save time and jump into work immediately.
Project description:
Figure one shows the details that might help me describe the project between our hands. We have an elevator car that travels up and down and can stop on one of four floors based on the passengers’ requests. We have 6 push buttons on the wall next to the elevator door that can send requests to call the elevator. In addition, there is a control panel inside the elevator cabinet in which there are push buttons to request stations to reach floors ...
Hello everyone, I hope you all are doing great. Today, I am going to share with you about "How To Calculate Liquidated Damages in Construction?" In almost all construction contracts that will be a clause that provides that the contractor will pay liquidated damages to the owner of the project in case there is a breach of contract. In construction, a breach of contract, which leads to the owner claiming liquidated damages, usually relates to a failure to complete a project in contractual time (that is, failing to complete works and handing over the house to the client at the date agreed on the contract).
When calculating liquidated damages, the client bases them on a daily or weekly rate – the amount a contractor is required to pay will depend on t ...
Hey, everyone, hope you are doing great. In today's article, we are going to explore C# Checked ListBox Control. In the previous article, we discussed in details about C# TextBox, C# Label, C# ListBox, C# ComboxBox and C# Button. C# Checked ListBox plays very important role in Point Of Sale applications. In some words, we can say this is a combination of check boxes and list. C# Checked ListBox is used to gain specific information from end-user. It's mostly used in survey-based application to gain the voting for a specific purpose.
We will work with Checked ListBox same as we have worked with ListBox & ComboBox. You can use C# Checked ListBox for multiple purposes. You can use this as the attendance taker to mark the attendance of students.
C# ...
Hello friends, hope you all are fine and enjoying in your life. In the previous post, we have seen How to use Oscilloscope in Proteus ISIS, today I am going share a new and a very important Tutorial which is How to Design a 5V Power Supply in Proteus? This project is very simple and of basic level but importance of this project is that it is used as a base in almost all large electronics project, designed now-a-days. When I start working on any project then the first thing, I need to design is this DC power supply, because without powering up the components, we can't use them. :)
While designing a 5V Power Supply in Proteus ISIS, we will be using Voltage Regulator IC, which is commonly known as 7805. This voltage regulator is used to regulate or c ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you detailed discussion on Introduction to LM2904. LM 2904 consists of two builtin amplifiers. These amplifiers have high gain and they are internally frequency compensated. These amplifiers are designed for the operation from a single power supply for a large range of voltages. We can also operate them from multiply power supplies as well.
LM-2904 operates on 3.3V power supply, it is the most common power supply in digital systems. LM 2904 is also available in small sizes i.e. they are available in the latest technology DSBGA. LM-2904 has a lot unique features in comparison to the other standard amplifiers. These features include large DC voltage ga ...
Hello friends, I hope you all are doing great. Today, I am going to share the 10th chapter in the PCB learning series. So far, we have studied the basics of PCB i.e. What is PCB? Main Types of PCB, techniques to mount components on PCB etc. Now, we are ready to have a look at the complete PCB Fabrication Process.
So, in today's tutorial, I am going to share a detailed guide on PCB Fabrication Process. We will discuss everything related to it i.e. How PCB boards are manufactured? Which material is used to fabricate printed circuit boards? etc. But before starting the Fabrication PRocess, we first have to understand a few terms/features. So, let's get started:
PCB of DVD player:
RoHS-compliant P ...
