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 ...
Hi friends and hope you are doing very well. Today we would like to take one tutorial which is very essential in the industry which is analog input processing for handling analog measurements of physical signals like temperature, humidity, pressure, distance, flow and level of liquids, etc. Typically, sensors produce two types of analog signals to represent the equivalent measured signal which is current and voltage signals. The currently produced signals would be within the range of 4-20 mAwhile voltage signals are in the range of 0-10 v. because, that output signals represent physical signals, the limits of output signals are 0 to 10 v for voltage based sensors and 4 to 20 mA for current-based sensors, these values should be scaled to represent ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an Introduction to LM741. It belongs to the series of general purpose amplifiers. It supports larger range of input voltages. LM741 provides high gain and short circuit protection as well. Its pins configuration is very similar to UA709 and there is no need of frequency compression in LM 741.
LM741 can be used as a comparator in order to determine the levels of applied input voltages i.e. either smaller or larger input voltages are applied at its input terminal. LM741 is an op-amp IC having 8 different pins, which will be explained later in this tutorial. LM-741 has a very wide range of applications e.g. function generator, comparator, DC amplifie ...
Data-driven design is a powerful tool that can help you create an effective product. By leveraging data to inform your decisions, you can ensure that the design of your product will be tailored to meet user needs and preferences. This in turn leads to increased engagement and satisfaction among users, as well as more successful products overall. In this article, we'll look at how to use data to inform your product design decisions – from understanding your data sources and analyzing user behavior & feedback all the way through refining the design based on feedback and results. With these tips in hand, you'll be well-equipped to create a successful product with a great user experience.
1. Understand Your Data Sources
Comprehend Your Information Sour ...
In the previous post Logical Gates in Ladder Logic for PLC, we had an overview of what is Ladder Logic programming and we have also implemented three basic Logical gates in Ladder Logic form. Today, we are gonna have a look at some complex Logical Gates in Ladder Logic for PLC. So, I hope till now you guys have basic knowledge of Ladder Logic and can implement complex logical gates in it. If you haven't read the previous post then must read because without that knowledge you won't understand this post.
In today's post we are gonna implement few complex logical gates. Its not gonna be much difficult if you have the basic concepts. I am just pointing out few important points here. While implementing any gate in ladder logic, always consider rung as ...
Industries from sales to healthcare rely on data to make business decisions and project key metrics. Tracking troves of customer, purchasing, and logistical data reveals trends that can boost revenue or uncover missed savings.
Storing and analyzing big data is essential for process audits. For example, a company’s ongoing shipping audits explained several issues, including patterns of overcharges and delayed deliveries. A customer experience audit can yield similar findings by noting bottlenecks in the customer journey. All of these processes require the input of large sets of readable data.
Businesses need a data normalization process to store and filter raw data into useful information that can inform these valuable processes.
What is Data N ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to start this new series on ASP.NET MVC Framework. I am gonna start from basics and will slowly move towards professional projects. I will share all the codes during this series and if you got into any trouble then ask in comments and I will help you out.
One of our Team Member has already designed videos on ASP.NET MVC and I will keep on embedding the respective videos throughout this tutorial series. In our first tutorial, we are gonna have a look at How to Setup your First Project in ASP.NET MVC Framework. So, let's get started with it:
Setup your First Project
I will use Microsoft Visual Studio 2015 and I hope that you have already installed it.
If you are usin ...
Hi readers! I hope you are doing great. We are learning about modern neural networks in deep learning, and in the previous lecture, we saw the capsule neural networks that work with the help of a group of neurons in the form of capsules. Today we will discuss the graph neural network in detail.
Graph neural networks are one of the most basic and trending networks, and a lot of research has been done on them. As a result, there are multiple types of GNNs, and the architecture of these networks is a little bit more complex than the other networks. We will start the discussion with the introduction of GNN.
Introduction to Graph Neural Networks
The work on graphical neural networks started in the 2000s when researchers explored graph-based semi-supervised learning in the neural network. The ...
Hello friends, I hope you all are fine and enjoying yourself. Today I am going to share a new project titled Interfacing of temperature sensor LM35 with Arduino UNO in Proteus ISIS. So far, I have only worked on temperature sensor DS18B20 for temperature measurements and I have also uploaded a tutorial on Interfacing of Temperature Sensor 18B20 with Arduino.
Recently I got a chance to work on a project regarding temperature sensing but the condition of this project was that to use only LM35 for temperature detection. Then, I get to know much about LM35, its operating conditions and features. So I thought I should also upload its tutorial as it will also be advantageous for engineering students. Because learning new things is always a charm.
An exc ...
Hello friends, I hope you all are fine and having fun with your lives. In today's tutorial, I am going to show you How to use Arduino Serial Monitor. It's not gonna be a very big post but its really very essential if you wanna learn Arduino coding. Because Arduino Serial Monitor is a great debugging tool and it helps a lot in Arduino Projects. In the previous post we have seen How to use digitalRead in Arduino and if you recall that tutorial then you must remember that in it we have used some Serial printing. So that's what we are gonna cover in today's tutorial.
Before going into the details, I must suggest you to first read these two posts because in those tutorials I have shown the serial communication which is essential for Serial Monitor Work ...
