Hi Guys! Hope you’re well. I welcome you on board. Thank you for viewing this read. In this post today, I’ll walk you through the Introduction to BC557.
BC557 is a bipolar junction transistor with DC current gain 300. It falls under the category of PNP transistors where one N-doped layer stands between the two P-doped layers. The continuous collector current is 100mA means it can drive load under 100mA. BC557 comes in the TO-92 package and is mainly used for switching and amplification purpose.
Before I bore you to tears, let’s dive in and read the complete introduction to BC557 covering datasheet, pinout, working principle, power ratings, physical dimensions, and applications.

Hello friends! Hope you are doing well. Today, we will have a look at the detailed Introduction to ESP8266 WiFi module. ESP8266 is a very low-cost & user-friendly WiFi module, which develops a simple TCP/IP connection and can easily be interfaced with microcontrollers via Serial Port. The first chip in this series was ESP-01 which gained sheer attention in the market.
In this tutorial, we will discuss the ESP8266 WiFi module along with its pinout, features, specifications, applications and datasheet. Let's dive in and nail down everything related to this device.
ESP8266 WiFi Module
ESP8266 (also called ESP8266 Wireless Transceiver) is a cost-effective, easy-to-operate, compact-sized & low-powered WiFi module, designed by Espressif Systems, that supports both TCP/IP and Ser ...
Hey Guys! Hope you’re well. I welcome you on board. In this post today, I’ll walk you through PCBA (Printed Circuit Board Assembly) in detail. It's our 4th tutorial in the PCB learning series.
In the 1st tutorial, we studied printed circuit board(PCB) in detail and learned that PCB provides physical support and electrical connection through conductive copper layers for the electronic components placed on the board. We have seen in our previous tutorials that when we place our PCB order on some PCB fabrication house, they provide us with a PCB board without electronic components. We have to solder the electronic components on the board. But now these PCB companies also offer a service to provide finished PCB boards with electronic components attach ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through why cybersecurity in the healthcare industry is vital.
The days of keeping records with pen and paper and storing the information into a file cabinet are gone. Now, we can effectively keep confidential information since technology saves both space and time, and it is more accessible.
The only problem with this new trend seen in the last couple of decades is the security issue. The healthcare industry, one of the most important industries in the world, contains information that must stay in safe hands, away from the eyes of hackers.
Below are some reasons why healthcare and healthcare cybersecurity professionals are so mindful to protect this ...
Hey peeps! Are you excited to begin with the new chapter in Python? Till now, we have been learning the data types and their related concepts. Now, we are starting a new chapter where you will learn the details of Object Oriented Programming or OOP. We are moving towards the advanced level of programming in Python, and here, you will go through the complex but interesting concepts that will show us the fascinating results on the screen. This will be more clear when you will know the basic information about the OOP, but before going deep, we will go through the headlines of the lecture:
How do you classify the programming languages?
How do you introduce the OOP?
Why object-oriented programming is important in Python?
How do you define class and objects in OOP and how are they connected? ...
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 ...
Hello friends, I hope you all are having fun. In today's tutorial, we will have a look at detailed Introduction to Enums in C#. It's our 23rd tutorial in C# series and this C# concept is quite easy one. It's normally used to give better meanings/understanding to your project.
If you haven't studied lectures on C# Classes & C# Methods, then do read them first, as we are going to use them today. So, let's get started with Introduction to Enums in C#:
Introduction to Enums in C#
Enums in C# ( short for Enumerations ) is a value type datatype for constants, created by using keyword enum and can be controlled by the class Enum. ( keyword with small e, while class with capital E )
We can declare & implement Enums directly in C# Namespace, c ...
It’s 2019, and everyone’s wondering if PBNs or Private Blog Networks are still worth building. Some would say yes, while others say no. Looking back at how it started (who can forget how Google penalized two public blog network and made them a cautionary tale?), there will always be proponents and opponents of this SEO technique.
PBNs gathered steam in 2014, but people have been searching about them since 2005 based on Google Trends. It is highly likely that it has been used by many SEOs since then or even earlier.
When it became the go-to strategy for grey hat SEO, the conversation went from “maybe” to “how to use PBNs effectively”. In fact, deciding which is the best solution for hosting became a critical part of building PBNs. After all, the c ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM4040. LM-4040 is specially designed for an accurate micro-power shunt voltage reference. These voltage references includes the standards of 2.5V, 3V % 5V respectively. LM-4040 has three different grade A, B and C grades and they have o.1%, o.5% and 1% tolerances respectively.
This device is available in different packages and each package has different individual dimension which will be explained later. We can achieve an excellent performance from this device when it is operating at the current ranging from 60uA to 15mA and its temperature coefficient is 20 ppm per degree. In order to maintain good stability ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Write a Technical Research Paper. Research projects help scholars prove theories or contribute to the development of knowledge in their fields. They document their successful projects in research papers. It is crucial to document the project professionally.
With that, interested parties can enjoy learning from your research. The ability to read through the paper determines how much the reader gains from it. For a student, it is the key to good grades. Below are the steps to writing an excellent technical research paper:
1. Know what your readers want
The research should not target your supervisor alone. You should prepare it for a broader audienc ...
