Hi Mentees! Welcome to another electronic tutorial about the 555 Timers. We are working on Proteus and in the present experiment, we'll design the circuit of Pure Sine Wave Inverter. Inverters are the opposite devices to rectifiers. We'll show you the meaning of this sentence in action Yet, before experimentation, we have to learn some predominant concepts about the experiment. So, We'll go through the following topics:
Introduction to Pure Sine Wave Inverter.
Components used in the circuit of Pure Sine Wave Inverter.
Working of the circuit of sine wave inverter.
Circuit simulation of pure sine wave inverter in Proteus.
Introduction to Pure Sine Wave Inverter
In electronics, we examine the output of devices in the form of waves. Basicall ...
Hello friends, I hope you all are happy, healthy, and, content. Today, our discussion is all about "Diodes". Whoever has been a science student, knows about diodes. Although it seems to be a tiny component of a circuit, apparently it is true but it has a lot of complexities or you can say, it's a storm in a teacup. You might have read a lot about diodes in physics, in today's discussion we would be moving step by step into the pool of diodes from definition to working of diodes, their types, and then lastly its applications. Let's get started!
Diode Definition
First things first, Let's define diode,
A diode is a basic discreet electronic component made up of semiconductor material, used in electronic circuits, which allows unidirectional c ...
There is no other area in the construction industry that needs a change more than resource management. Resource management is how you manage, plan, and allocate your workforce. Effective construction workforce management can help you understand aspects like:
Which construction project needs more hands?
Identify over and under-allocated staff.
Track experience and skills with project history.
Simply put, effective workforce management helps contractors coordinate work and people, ensuring that everyone has the details or information required to do their jobs. However, in order to maintain a productive workforce, contractors have to put in plenty of time and hard work.

Hello friends, Hope you are doing good and having fun. I am here with another article on the blockchain. Previously, we have discussed the blockchain, some of its concepts, and its characteristics, and today I will talk about transactions. We would also explore the concept of gas in this tutorial. So let’s start by defining a transaction.
What is Ethereum Transaction?
A transaction is a message signed by an account owner that is added to a block and recorded in the blockchain.
A transaction is initiated by an externally owned account and then it gets transmitted to the Ethereum network.
It can be originated only by an externally owned account (an account owned by a human) and not by a contract account.
Through transactions, one can inter ...
Hello friends, hope you are doing fine and doing great. In the previous tutorial for introducing Smart Contracts, I told you about Solidity. Solidity is a high-level programming language for writing smart contracts. It is the most popular programming language for Ethereum. So, in this article, I will explain the basic components of solidity. Let’s get started by revising the key points of solidity.
Solidity Programming
Solidity programming language is made for writing code for the Ethereum platform. These codes (smart contracts) help in executing different functions in Ethereum virtual machine (EVM).
It is easy to learn the language. If you are familiar with C and JavaScript, you can easily learn solidity.
The code written in solidity is con ...
Hello guys, hope you are doing good and enjoying your lives. Today, I am going to introduce you to the blocks of a blockchain. I gave you an understanding of blockchain, its characteristics, and some idea about accounts and wallets in my previous tutorials, and today my article is about the structure of a block in the blockchain.
I will first define the block before going into the details about its structure. So let’s start without any further delay.
Block in Blockchain
A block is actually the building block or the key element of a blockchain.
The definition of a blockchain is based on its blocks. As I defined in my previous posts, a blockchain is a chain of multiple blocks.
Blocks contain transac ...
Hello friends, I hope you are happy, healthy and content. We have been discussing embedded systems lately and this discussion would be incomplete without an in-depth discussion on Real time embedded systems. You might have observed their utility and their absolute need in our constantly changing external and internal environment, the ease of managing the room temperature with a single tap, generating several results with a single click and streaming videos and playing games anytime and anywhere are the blessings of real time embedded systems.
Definition of Real Time Embedded Systems
Real time embedded systems can be defined as;
"The embedded systems which respond to real time situation with the help o ...
LendInvest makes property finance simpler. Bridging loans, development finance, and buy-to-let mortgages for intermediaries, landlords, and developers made it easier.

Hello friends, Hope you are doing fine and having a good time in your life. The topic that I am going to discuss today is a very interesting and important one in the context of blockchain. I will discuss smart contracts in this article and I am sure you will learn the concept by the end of this tutorial. I have mentioned smart contracts in my previous articles and defined them before.
Before discussing smart contracts, let’s first revise what a contract is, and then we will talk about smart contracts.
Contract
When two persons or two parties want to carry out a deal or a transaction such as buying property, they need some proof for future reference.
So, a contract between two or more individuals is a legal document that serves as proof for t ...
Hello friends, hope you are doing fine and enjoying your life. In today’s article, I am going to discuss decentralized applications that are abbreviated as dApps. With the invention of blockchain technology and afterward Ethereum, the idea of decentralized applications has gained a lot of attention. So let’s get into the details and learn what a dApp is.
Decentralized Applications (dApps)
An application built on a decentralized platform such as Ethereum is called a Decentralized Application(dApp).
A dApp generally consists of a backend and a frontend.
The backend of a dApp is a smart contract mostly written in solidity language.
The front end of a decentralized application is the user in ...
