Hello pupil! We hope you are doing well with object-oriented programming with Python. OOP is an extremely important topic in programming, and the good thing about Python is that the concept of OOP can be implemented in it. In the previous lecture, we made a basic introduction to all the elements that are used in the OOP, and right now, we are moving forward with the detail of each concert with examples. The imperative nature of the OOP is useful for us because it uses the statements to change the programming state, and in this way, the working of the code becomes easy and effective. To use the applications of Python, the imperative nature of OOP will give us the tools we need to get the perfect results by using our creativity. We will prove this in just a bit, but here are the highlights o ...

We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.

Hello everyone, I hope you guys are having fun with your lives. In today's tutorial, we are gonna have a look at How to use Button in C# Windows Form. In our previous tutorials, we have first discussed the Introduction to C# Windows Forms in which we have created our first C# Windows Forms Project. After that we have discussed How to add C# Controls in Windows Form, in which we have added different C# controls in that Windows form.
So, now we are gonna add back end programming in those Controls one by one. In today's tutorial, I am gonna add the code for the Buttons and you will see that it won't be any difficult to use them in your projects. So, let's get started with How to use Button in C# Windows Form.

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 ...
Hello Python programmers! Welcome to the engineering projects where you will find the best learning data in a precise way. We are dealing with Python nowadays, and today, the topic of discussion is the arrays in the language. We have seen different data types in Python and discussed a lot about them in detail till now. In the previous lecture, we saw the details of the procedures in dictionaries. There are certain ways to store the data in the different types of sequences, and we have highlighted a lot about almost all of them. It is time to discuss the arrays, but before this, it is better to understand the objectives of this lecture:
Introduction to arrays
Difference between contiguous and non-contiguous memory locations
One-dimensional arrays
Functions in arrays
What are Arra ...
USART is the acronym for Universal Synchronous-Asynchronous Receiver-Transmitter, and is the advancement of the old UART that was unable to handle synchronous communications; in computers, it deals with the management of communication via the RS-232 interface.
Generally, in the communication between devices, there is a transmitter and receiver that can exchange data bidirectionally, thus it happens for example in the communication between the microcontroller and third-party peripherals.
What is Serial Communication?
In serial communications, the transmitting device sends information (bitstream) through a single channel one bit at a time. Serial communications are distinguished from parallel communications where the bitstream is sent over several d ...
Hi Everyone! Hope you all are doing great. We always love when you keep coming back for what we have to offer. Today, I am going to give you a Introduction to C# Classes. We have already seen Introduction to Data Types in C# which includes boolean, integer, char and double. However, if you want to make complex custom type, you can make use of classes. I'll give you a brief introduction to classes so you don't have to go anywhere to find information regarding classes in C#. Let's hop on the board and dive in the details of classes.
Introduction to C# Classes
Class in C# is referred as a blueprint of complex data type that describes the behavior and data of type.
If you want to create complex custom type, we use class. What do I mean by complex ...
Thank you for joining us today for our in-depth Raspberry Pi programming tutorial. The previous guide covered the steps necessary to connect a fingerprint scanner to a Raspberry Pi 4. In addition, we developed a python script to complement the sensor's ability to identify fingerprints. Yet, in this guide, we'll discover how to interface a ws2812 RGB to a Raspberry Pi 4.
Bright, colorful lights are the best, and this tutorial shows you how to set up Fully Configurable WS2812B led strips to run on a Pi 4 computer as quickly and flexibly as possible. In that manner, you can have the ambiance of your home reflect your tastes.
In most cases, when people talk about a "WS2812B Strip," they mean a long piece of extensible PCB with a bunch of different RG ...
Welcome to the fourth lesson of this python course. Our previous session taught us how to utilize the print function in python, so we have a firm grasp of the terminology and the functions themselves. In this lesson, we'll cover a few more Python terms, such as:
Strings
Operators
Input function
Also, we'll build a simple program to print out an imagined dog so that we may better grasp how these concepts are employed. So, let's get started now.
Why do we need to understand these terms?
Programming is a lot like building a structure out of blocks. Even with just a few types of children's toy blocks and some time and imagination, you can build anything. Because we'll be utilizing these phrases all the time in programming, it's critical that you know what they mean and how to use th ...
Greetings Learners! Welcome to the new lecture on Python. Today we are moving towards an interesting and important concept. If you have come from a programming background, then you must know about the workings of loops. To make the repetition of the same sequence, we use loops. We are familiar with the sequences in detail as we have learned them in the previous lectures and have received the concept in the recent lecture. If you want to be a programmer, then you can not move forward without a solid base of loops; therefore, in this lecture, we will learn the concept of loops from scratch and then go on to a deep understanding of each loop in the next episodes. So have a look at the concepts that you will learn today.
What are the loops?
How do we understand the concept of loops from scra ...
