Hello guys, I hope you all are doing great. In today's tutorial, I am gonna give you a detailed introduction of Modified Sine Wave Inverter with code. In this inverter series, I have first explained the Basics of Inverters with Topology in which we have seen the Introductionof inverter and its different types. After that, we have discussed the Major Components of Inverter which are essential for its designing. Now in today's post, I am gonna explain the modified sine wave inverter. I have used AVR microcontroller in this project. Before starting on modified sine wave inverter, you should also read this Pure Sine Wave Inverter. I tried my best to keep it simple but still if you guys got stuck at any point ask in comments and I will remove your quer ...
Hello friends! How are you today? Today we're going to discuss a project that is interesting and also useful in our everyday life. You see QR codes almost everywhere, right? They are printed on almost every product's package, leaflets, newspapers, and brochures.
Perhaps, you often use QR code scanners on your mobile device. What about making such a program by yourself? Yes! That is exactly what we are going to do today. We will make a QR code scanner using the ESP32-CAM. For image processing, we will use the OpenCV library.
If you’ve ever wanted to create a real-time QR code scanner using a low-cost, wireless camera module, you’re in the right place. In this tutorial, we’ll walk through setting up an ESP32-CAM to stream video and using OpenCV to detect and decode QR codes in real time.

Hello Everyone! Happy to see you around. In this post today, we’ll cover the 2SC2240 NPN Transistor. We will have a look at the 2SC2240 Datasheet, Pinout, Power Ratings, Equivalents & Applications.
Electrons are the majority charge carriers in this NPN transistor, in contrast to PNP transistors, where holes are the majority carriers. The 2SC2240 comes with a power dissipation of 0.3W, the amount of energy this transistor dissipates while operating in the forward-biased state, while the collector current is 0.1A means it can support load up to 0.1A.
This NPN transistor contains 3 terminals, named:EmitterCollectorBase
If the voltage at the base terminal is above 0.7V, the transistor will get forward-biased and the current will start flowing from Collector to Emitter terminal. If the ...
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 everyone, I hope you are doing great. In this article, we will talk about C# TextBox Control. In the previous articles, you have already get familiar with C# Button Control & C# Label Control, this is the sequence of those. In short C# TextBox Control is just same as the other expect some few changing. Before getting started with C# TextBox you must have knowledge of previous concepts. It's not essential but it will give you the edge to understand the advanced elements of C#.
C# TextBox is used to get input from users or it can also be used to display some values to the user. The textbox is a container for text blocks, you can take inputs or show the text as you required in the form of paragraphs. If you used TextBox as the input field t ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM339. LM339 belongs to the family of devices having 4 independent voltage comparators. Each comparator is designed in such a way that it is capable of operating from a single power source over a wide range of power supplies. It can also operate for split power supplies. There is a unique characteristic of comparators, Input Common-Mode Voltage Range (ICMR) includes a ground even when it is operating from a single power supply voltage.
Basically, LM339 is a comparator IC having four built-in comparators. The basic purpose of a comparator is to rotate the signal between analog and digital domains. At its input termina ...

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 everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Calculating Values of Trigonometric Functions in MATLAB. Trigonometric function have a great importance in latest mathematics. There are six types of trigonometric functions out of which first three are used more frequently in comparison to the other three. Trigonometric functions are important in the study of triangles.
Trigonometric functions show the relationship between the angles of the triangle and the lengths of its sides. The positive and negative signs with the trigonometric functions indicate the portion of the quadrants. Well known theorem of mathematics i.e. Pythagoras Theorem is used in case of the right angle triang ...
Milling machines are the backbone of any workshop, whether you're crafting aerospace parts or tuning up motorcycle brackets. With the sheer range of options out there, it’s easy to get lost in the noise.
Still, you must understand that choosing the right milling machine is a crucial investment that must be done carefully. The machine determines your precision, productivity, and long-term shop performance.
Your project needs, material type, and budget all shape the right fit. Key factors include the machine type (CNC, manual, vertical, or horizontal), spindle power, and available workspace.
This guide breaks down the fundamentals to help machinists, hobbyists, and production operators make confident decisions based on real needs.
Understand Your Milling Needs
Start with the ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to LM35. LM35 is a type of commonly used temperature sensor, that can be used to measure temperature with an electrical output compared to the temperature in (°C). In can measure temperature in a better way than a thermistor.
LM35 is used in industries and commercial buildings where high accuracy of temperature measuring is needed. I will give you a detailed overview of this temperature sensor in today’s post where we will have a look its pinout, working, protocol, etc. I will also share some links of projects where I have interfaced it with Arduino or other microcontrollers. If you have any questions please ask in the comments, I will resolve your queries and will gu ...
