Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at detailed Introduction to Entity Framework Core. It's our 16th tutorial in ASP.NET Core series. So far, we have covered the the MVC architecture and few concepts related to object oriented programming and now we are ready to get our hands on Databases.
So, today we will cover data handling in detail, which is done by Entity Framework Core in .NET Core applications. So, let's first understand this Entity Framework Core:
Introduction to Entity Framework Core
Entity Framework Core ( normally called EF Core ), designed by Microsoft, is an open source, flexible, extensible, lightweight and cross-platform framework, whic ...
Thank you for being here for today's tutorial of our in-depth Raspberry Pi programming tutorial. The previous tutorial demonstrated the proper wiring of the photoresistor sensor to the GPIO pins. Finally, we learned how it might be included in a Python script for data collection and analysis needs. We also looked at the functions of each component in the circuit. However, I'll walk you through installing a Pi 4 Print Server in this guide. While installing the program is straightforward, setting it up so that a Windows network can locate the print server requires a little more effort. Rather than spending hundreds of dollars upgrading to a laser printer, you may easily upgrade your current USB printer to laser quality by installing a print server.
Because of this software, you no longer ha ...
Our next step in the Raspberry Pi training program is to get zero tiers up and run on a Raspberry Pi 4. How to utilize a Raspberry Pi to measure internet speed and store the results in Grafana or Onedrive was the topic of the last piece. During the project, you will discover how to install ZeroTier on a Raspberry Pi and get it up and running. We will also learn how to set up a firewall to secure our network.

What is zeroTier
ZeroTier is a software that provides a streamlined web-based interface for constructing virtual networks connecting various gadgets. Somewhat akin to configuring a virtual private network on a Raspberry Pi, these networks exist only in cyberspace. The process o ...
Hey peeps! Welcome to the Engineering Projects where you are learning the basics of Python in detail. We are working a lot with the arrays as these are important concepts in most of the high-level programming languages till now, the numeric data was used in the arrays but for our practice, we are moving towards the next step where the focus will be on the string data type. The practice is done on the Jupyter notebook and every step is going to be explained well without skipping any concepts but to keep things easy, we are not emphasising unnecessary details and concepts. So, before going deep into the topic, have a look at the list of the contents that will be discussed in this lecture:
What are the strings?
How do we use the string in arrays?
What is the list?
How do we extract the ch ...
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 ...
Hello friends, hope you all are fine and having fun with your lives.In today's post, we are gonna see How to use timer interrupt in 8051 Microcontroller.8051 Microcontroller comes with timer as well. They normally have two timer in them named as Timer0 and Timer1. These timers are used for counting purposes like you want to start some countdown in your project then you can use these timers or you wanna create some clock then in that case as well you need timers. So, in short there are numerous uses of timers in a project. Timers are also used for delays like you wanna create some delay of 10 sec but you dont wanna use the delay function in your project so you can use timers. You start the timer and then when it comes to 10 seconds then you can do ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4. This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work.
What is time-lapse?
When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras.
Components
Raspberry pi 4B
Pi camera
Connect to the Raspberry Pi
Cameras that can be used with the Raspberry Pi are a bit limi ...
Hey, peps! Welcome to the new tutorial on the Jupyter notebook. As we are moving towards a higher level of Python, therefore, it is important to understand other ways of doing the same task. As we read in the previous lecture about 2D arrays, this time it is going to be done with the help of a famous library in Python. This time, you are going to learn different, engaging, and advanced-level concepts that not only help you deal with the 2D array but also the installation and working of the unique library of Python, which is NumPy. This lecture is going to be very useful and interesting, and therefore, we suggest you have a glance at all the goals of this lecture.
Getting the introduction to NumPy
Successfully installation of NumPy and knowing different methods for it
Using the arrays wi ...
Hey peeps! Welcome to the new tutorial for the Python programming language, where we are at the point where we are going to learn about the loops. Loops are fundamental concepts in programming, and if we talk about Python, there is a smaller variety of loops in it, but the most important ones are available to practice in Python. In the last session, there was a long discussion about the while loop in detail. We had seen some examples and the details of the statements that can be used within the while loop. In the present lecture, we are going to discuss the second type of loop in Python, that is, the for loop. You will go through the training of every important and basic step about this loop, but first of all, you have to look at the basic list:
Why do we prefer for loop over some other c ...
PWM stands for Pulse-Width Modulation. Once the switching frequency (fsw) has been chosen, the ratio between the switch-on time (TON) and the switch-off time (TOFF) is varied. This is commonly called duty-cycle (D). The duty cycle can be between 0 and 1 and is generally expressed as a percentage (%).
D = TON / (TON + TOFF) = TON x fsw
The variation of the pulse width, made at a high frequency (kHz), is perceived as continuous and can be translated into a variation of the rotation speed of a motor, dimming a LED, driving an encoder, driving power conversion, and etc. The use of PWM is also widely used in the automotive sector in electronic control units (ECU - Electronic Control Unit) to manage the energy to be supplied to some actuators, both fix ...
