Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us how to use a raspberry pi as a DNS server. We also looked at the benefit of this DNS server. This tutorial will teach us to set up Raspberry pi as a VPN server.
This is an excellent method for increasing your network security and getting access to your local area network from the world wide web, but setting up your VPN server might be a challenge. Pi VPN uses a guided install to turn your Raspberry into a low-cost, high-performance VPN server.
What is Pi VPN?
It is an OpenVPN server optimized for all Raspberry platforms above pi 2. It allows you to access your home network over the internet safely and securely. Smart devices and your network can ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention.
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32.
We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
Hi Friends! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through the Top 10 Workflow Automation Software.
Running a business is not an easy job. It requires a lot of deliberate effort and careful attention to run business processes successfully. Some tasks involved are repetitive and time-consuming, making it difficult for you to do them manually. This is where workflow automation comes in handy that doesn’t require human intervention and can be used to effectively manage and execute business processes.

Hi Guys! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through Types of Cloud Computing.
Cloud computing is not a new term. Companies have been using this infrastructure for the past two decades. You might be familiar with this term, in case you don’t, cloud computing is the on-demand availability of computing resources over the internet. Simply put, you can process, store and manage a large amount of data using this architecture. The companies offering these services to end-users are called Cloud Service Providers (CSP). And most of these services offer the pay-as-you-go model which means you can ask for only those computing resources required for your business; you don’t pay for the resources you don’t use in the cloud computing model. This ...
Hello, Students here I am present to cover an article on a series of Electronic devices and circuit theory. The foremost article of this series is Ideal diode vs practical diode. I try to elaborate on basic to modern theory related to the diode. This component act as fundamental to many important circuit devices such as rectifiers, transformers, etc. The question which we cover in this article are;
What is a diode?
How a diode is formed? Which methodology manufacturer utilized while the formation of the diode?
What is the concept of doping and PN junction in diode theory?
How does a Diode work?
What type of biasing allows a diode to conduct? Under which situation of biasing diode offers a restriction while conducting?
Upon which cha ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
The Industry 4.0 market size will reach $267.01 billion by 2026. Industry 4.0 depends on the secure, fast, and cost-effective data transfer between IoT devices. IoTA is designed to ensure secure communication between two devices within the IoT(internet of things) framework. Let's have a detailed look at the role of IoTA in industrial IoT.
Understanding IoTA- how it's different from blockchain
The terms MIOTA and IoTA together make up the term IoTA. While MIOTA is a cryptocurrency, IoTA is a non-profit foundation. Since its inception in 2015, IoTA has formed joint ventures with firms like
Fujitsu
Samsung
Telekom
Volkswagen
IoTA is technically different from blockchain in terms of the underlying technology. IoTA works on a technology ca ...
Hello readers, I hope you all are doing great. This is the second tutorial of the Raspberry Pi programming series. In our previous tutorial, we discussed the basic features and hardware architecture of Raspberry Pi Pico.
In this tutorial, we will discuss the various available development environments for programming the Raspberry Pi Pico. Later, in this tutorial, we will also discuss the installation of Visual Studio Code for Pi Pico programming.

RP2040 supports multiple programming languages like C/C++, Circuit python, and MicroPython cross-platform development environments. Raspberry Pi Pico module consists of a built-in UF2 bootloader enabling programs to be loaded by drag and drop and floating point routines are bake ...
This is the third tutorial in our Raspberry Pi programming course. In the previous chapter, we learned how to install Raspbian on our Raspberry Pi mini-computer. In this chapter, we'll learn how to use a VNC server to remotely control and see its desktop from our computer.
What is VNC?
Computing over a network is known as "virtual network computing," or "VNC." To remotely control another computer, you can use this screen-sharing technology, which works on all major operating systems. As a result, a remote user can interact with a computer's display (screen, keyboard, and mouse) as if they were sitting right in front of it.
VNC takes advantage of the client/server concept. Rather than installing a VNC s ...
Hello friends, I hope you all are doing great. Today, I am going to start a new tutorial series on Raspberry Pi 4. It's our first lecture today, so I will explain the basics of Raspberry Pi boards. In this tutorial series, I will teach you each and everything about Raspberry Pi and its programming. I have designed this guide for beginners, so we will start from the very basics and will slowly move toward complex concepts. Python programming language is used in Raspberry Pi boards, so we will study Python as well. So, we will learn both programming and hardware circuit designing in this tutorial series. Let's first have a look at What is Raspberry Pi?
What is Raspberry Pi?
Raspberry Pi is a series of Single Board Computer, developed by the Raspberry Pi Foundation in England, to teach co ...
