Greetings! This is the complete project of our Raspberry Pi 4 tutorials. In our previous tutorial, we learned to set up our raspberry pi as a virtual private network server. In this tutorial, we will design a smart attendance system using an RFID card reader, which we will use to sign in students in attendance in a class.
First, we will design a database for our website, then we will design the RFID circuit for scanning the student cards and displaying present students on the webpage, and finally, we will design the website that we will use to display the attendees of a class.
Components
RFID card kit
Breadboard
Jumper wires
Raspberry pi 4
I2C LCD screen
Design a database in MySQL server
Additionally, the Database server offers a DBMS ...
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 ...
Hey peeps! Welcome to the new lecture on the sequence data type, where we are discussing the range data type. We are interested in working on deep learning, and for this, we are learning the Python programming language from scratch. If we talk about the previous episode, we saw the byte and byte array methods that were amazing for converting the different data types into bytes. The current lecture will discuss the range data type, which is slightly different from the other types of sequences, so students will learn new and interesting concepts in the lecture; however, before we get into the details of our topic, take a look at today's highlights:
What is the range function?
How can you elaborate on the syntax of the range function in detail?
What are the three types of range functions ...
The "Hello, World!" program is a computer programming classic that has stood the test of time. For beginners, "Hello, World!" is a simple and full first program that introduces the basic syntax of programming languages and can be used to evaluate systems and programming environments.
The more you learn about Python, the more you may use it for your own purposes. Data analyst, application developer, or the ability to automate your work processes are all examples of jobs that can be automated.
This Python 3 tutorial will show you how to create a simple "Hello, World" program. Python's basic syntax and components include the following:
Variable-types
Data structures
Math operators
loops
Different function calls
Input and output functio ...
Hey learners! Welcome to the new tutorial on deep learning, where we are going deep into the learning of the best platform for deep learning, which is TensorFlow. Let me give you a reminder that we have studied the need for libraries of deep learning. There are several that work well when we want to work with amazing deep-learning procedures. In today’s lecture, you are going to know the exact reasons why we chose TensorFlow for our tutorial. Yet, first of all, it is better to present the list of topics that you will learn today:
Why do we use TensorFlow with deep learning?
What are some helpful features of this library?
How can you understand the mechanism of TensorFlow?
Show the light towards the architecture, and components of the TensorFlow.
In how many phases you can complete t ...
If you plan to run a start-up, it helps to have some basic understanding of IT management. Here are some key pointers on how best to manage your business IT systems:
You should know how your IT systems work and how they can be managed. This will help you keep them working well, which is especially important if your business depends on them for important functions like payroll or customer service. The earlier in the process that someone understands their role and responsibilities in running the company's technology, the better off they'll be when troubleshooting problems arise later on down the road.
How to Manage IT Management for Start-Ups
Make sure your hardware and software are secure.
Ensure that you have the right licenses for your ...
Hi there! I hope you are having a great day. The success of the field of deep learning is due to its complex and advanced neural networks. These networks can be broadly divided into traditional and modern neural networks. We have seen the details of traditional neural networks, and in the previous session, the basic introduction of modern neural networks and the details of their features were discussed. Today, we will talk about one of the most famous modern neural networks, the Kohonen Self-Organized Neural Network.
Modern neural networks are more organized and developed than traditional neural networks, but that does not make traditional neural networks less efficient than modern ones. All the networks are introduced for specific tasks, and this is one of the main reasons behind t ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to use String in Python. It's our 3rd tutorial in Python series. We have discussed strings in our previous lecture How to use Data Types in Python.
String is a most commonly used data type in python that's why I have created a separate lecture on it. Python has many built-in string operations, which we will discuss today in detail. So, let's get started with String in Python:
How to use String in Python
String Data Type is used to store or collect one or more characters or sequence of characters, we can place any alphanumerical or special character in a string.
Let's create a string in python, it has a simple syntax, as shown below:
first_var = "He ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Increase EF Core Performance for Saving Multiple Entities? EF Core works well for simple CRUD operations but for saving multiple entities EF Core provides poor performance. So, today we will use a third-party EF Core extension named "Z.EntityFramework.Extensions.EFCore", designed by ZZZ Projects, which will increase the EF Core performance significantly. I will be using a BulkSaveChanges Method of this library which is specifically designed for saving bulk data in an SQL database.
ZZZ Projects is a trusted company and has designed numerous .NET libraries, a few having downloads in millions. So, you can completely trust this extension library.
Here' ...

Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, a facial recognition system on a Raspberry Pi 4 was used to develop a smart security system. We also learned how to create a dataset using two Python scripts to train and analyze a series of photographs of a certain person. This tutorial will teach you how to install pi-hole on a Raspberry Pi 4 and use it to block advertisements from anywhere. This is a great initiative for folks who are tired of annoying pop-up adverts while browsing. First, we'll learn how to set up the pi-hole without the need for an environment, then we'll use Docker to install pi-hole, and ultimately we'll see how we can access it from anywhere.
