Introduction
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.

Following this, we will configure bitwarden and host it on our Raspberry Pi 4. The last tutorial discussed utilizing a Raspberry Pi to install and run zeroTire on pi 4. By the end of the project, you will have learned how to set up a Raspberry Pi 4 with the necessary software for password management, including bitwarden, docker containers, and portainer, and how to configure their respective user interfaces.

An effective password manager is a must-have. For the past decade-plus, I've relied on a password manager. The catch is that not all security-focused apps are created equal. Initially, I relied on password managers in my browser, but I soon switched to KeePass. It was an intelligent move ten years ago. The export f ...
Welcome to today's article on our comprehensive Raspberry Pi 4 programming guide. As we saw in the previous article, the Raspberry Pi 4 may power a single seven-segment display. In addition, we also interfaced a Raspberry Pi with 4 Seven-Segment Display Modules to display the time. However, this guide will show you how to construct a Raspberry Pi 4 crypto miner that uses very little electricity.
Cryptocurrencies have been the subject of widespread conversation for some time now. It's possible to use your computer to create them, and they can be used as currency. Because of this, the Raspberry Pi can also be used for Bitcoin mining. It's also possible to mine other cryptocurrencies. One drawback of mining is that the cost of electricity often excee ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to use IF Else in Python. It's our 5th tutorial in python series. In our previous lectures, we have covered the detailed Introduction to Python and then we have also discussed Data Types in Python & How to use Strings in Python. So, now it's time to move on a little further.
In today's tutorial, we will cover If else statement in python and its not that difficult to understand but quite an essential one as its use a lot in programming projects. So, let's get started with How to use IF Else Statement in Python:
How to use IF Else Statement in Python
IF Else Statement in python takes a Boolean Test Expressio ...
Hello peeps! Welcome to the new episode of the Python tutorial. We have been working with different types of data collection in Python, and it is amazing to see that there are several ways to store and retrieve data. In the previous lecture, our focus was on the basics of dictionaries. We observed that there are many important topics in the dictionaries, and we must know all of them to make our base of concepts solid. For this, we are now dealing with the dictionaries in different ways, and this tutorial is going to be very interesting because we will pay more heed to the practical work and, by choosing a few cases in our codes, we will apply multiple operations to them. So have the highlights of today’s learning, and then we will move forward with the concepts.
What are nested diction ...
To become familiar with the world of microcontrollers it is necessary to have a development board (also known as a kit), which generally allows you to start working on it easily. Fortunately, the ST provides a wide portfolio of development boards. In this guide, we will describe and use the Nucleo board.
The Nucleo has been introduced a few years ago and its line is divided into three main groups:
Nucleo-32;
Nucleo-64;
Nucleo-144.
Nucleo-32 Development Board
The number of pins available, so the package, gives the name to the board: Nucleo-32 uses an LQFP-32 package; Nucleo-64 and LQFP-64; Nucleo-144 an LQFP-144. The Nucleo-64 was the first line introduced and counts 16 different boards.
The Nucleo boards have interesting advantages compa ...
The choice of operating system for a virtual private server depends on the needs of a particular company. But if you are looking for a reliable, efficient, and flexible solution to host your web projects, in most cases it will be Windows VPS. In this article, we'll analyze why many people prefer Microsoft solutions, and what benefits and limitations you can expect if you decide to buy a Windows VPS
.
What is a Windows VPS and what it is used for?
Windows VPS is a virtual private server that uses Windows Server as the underlying operating system. Windows VPS functions effectively as a cloud server with elastic scalability. This means that you get a dedicated server resource that you can use as you see fit, and you can easily add resources as ...
Artificial intelligence is becoming more and more important for data security. In this post, we'll look at how AI may assist businesses in anticipating and thwarting threats. But before going ahead we will explain the terms artificial intelligence and machine Learning.
What Is Artificial Intelligence
Artificial intelligence (AI) is a discipline of computer science that focuses on making electrical equipment and software intelligent enough to do human activities. AI is a broad concept and a basic subject of computer science that may be used to a variety of domains including learning, planning, problem solving, speech recognition, object identification and tracking, and other security applications.
Artificial intelligence is divided into n ...
We will use for our examples STM32CubeIDE released by ST and completely free. STM32CubeIDE is a development tool and supports multi operative system (SO), which is part of the STM32Cube software ecosystem. STM32CubeIDE allows using a single platform to configure peripherals, to generate/compile/debug the code for STM32 microcontrollers and microprocessors. The framework used is Eclipse®/CDT, as tool-chain for the development is used GCC toolchain and GDB for the debugging.
To start the project, you must first select the MCU and then initialize and configure the peripherals the user wants to use. At this point, the initialization code is generated. At any time, the user can go back and change initializations and configurations, without affecting t ...
Hello peeps. Welcome to the next tutorial on deep learning. You have learned about the neural network, and it was an interesting way to compare different types of neural networks. Now, we are talking about deep learning frameworks. In the previous sessions, we introduced you to some important frameworks to let you know about the connection of different entities, but at this level, it is not enough. We are telling you in detail about all types of frameworks that are in style because of their latest features. So before we start, have a look at the list of concepts that will be covered today:
Introduction to the frameworks of deep learning.
Why do we require frameworks in deep learning?
What are some important deep learning frameworks?
What is TensorFlow and for which purpose of using Ten ...
