Hello everyone, I hope you are having a fine day. In today’s tutorial, I am going to discuss “Software Testing and Debugging”
During testing and debugging, seek advice for the various techniques of detecting and eliminating mistakes in a program, so that it produces the desired result. Every programmer needs to be aware of the truth that a program does not always run perfectly for the first time. It is consequently vital to make efforts in case you do stumble on the errors. First, determine and note any errors which are found during the very first building and running of the program.
Errors that Occur during Initialization of the Program
Many errors can occur when running a program, some apparent, and others are not. All these mistakes can be grou ...
We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. I will show you how to install and connect the RFID card chip to your Raspberry Pi through step-by-step instructions.
Modern security systems would only be complete using radio frequency (RFID) devices. To control who can enter a facility or which rooms they can access, RFID chips and card readers are employed. The RFID card's unique identification number can be read wirelessly with a wall-mounted RFID reader. A door will only unlock and allow entry if the RFID card's unique identification number matches a list of approved cards.
It's fun to tinker with this circuit, and it may be used in many other applications, from opening locks to taking a ...
Hi Geeks, welcome to our new project. Our new project is one of the most common issues you’ve seen in your cities. In this project, we are going to make a car parking system with automatic billing. In the entire world, there are an estimated 1.4 billion cars on the road, which is absolutely great news if we are considering the development of the Automobile industry. But the most serious issue is that the number of cars exceeds the number of available parking places, resulting in traffic congestion. Damaged cars due to this lack of space, fewer parking locations, lack of parking signage, informal parking, and overcharging for parking are just a few of the issues.
People are still choosing manual parking methods, which have a number of drawbacks, suc ...
Hello friends, I hope you all are feeling great today. In today’s tutorial, we will have a look at a detailed “While Loop In JavaScript” topic. It’s our 8th tutorial in JavaScript Series.
Loops are used in programming and they offer the easiest and quickest way to do a repetitive task. In this article, we will learn about While and do..while statements as they are the most basic type of Loops.
For example, if we want to display the same line “I am learning JavsScript” 10 times. Then this can be done with the help of loops easily rather than typing long code. It will save your time and energy.
While Loop in JavaScript
In JavaScript, while loops loop through a block of code until the specified condition is true. The condition is evaluated before ...
The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start.
Pressure
The definition of pressure according to fluid mechanics is as follows:
Pressure is the normal force applied by a fluid per unit area.
Unit of Pressure
The units of pressure Pascal is too small to deal with in practical cases. For instance,
Kilopascal: 1kPa=103Pa
Mega Pascal: 1MPa=106Pa
The three common pressure units used are standard atmosphere ba ...
Welcome back to another Python tutorial for the Raspberry Pi 4! The previous tutorial showed us how to construct a Raspberry Pi-powered cell phone with a microphone and speaker for making and receiving calls and reading text messages (SMS). To make our Raspberry Pi 4 into a fully functional smartphone, we built software in Python. As we monitored text and phone calls being sent and received between the raspberry pi and our mobile phone, we experienced no technical difficulties. But in this tutorial, you'll learn how to hook up the PCF8591 ADC/DAC module to a Raspberry Pi 4.
Since most sensors only output their data in analog values, converting them to binary values that a microcontroller can understand is a crucial part of any integrated electroni ...
Hello friends, I hope you all are doing great. Today, I am going to share the second tutorial in ASP.NET MVC series and I will explain the concept of Model in ASP.NET MVC. In our previous tutorial, we have seen How to Setup Your First Project in ASP.NET MVC.
So, before developing our web app, we first have to discuss some concepts in MVC Framework and Model is one of them, which we will cover in today's tutorial. So, let's get started with it:
What is a Model in ASP.NET MVC ?
In, ASP.NET MVC Framework structure, we have to understand 3 very simple blocks, which are:
Models
Controllers
Views
Model connects our web application with our SQL Database, it takes commands from the Controller and then get or set values in the Database an ...
Selecting the right BLDC motor for electric vehicle applications involves more than comparing specs — cooling method is one of the most consequential decisions in EV powertrain design.Most guides tell you water cooling is "better." That's not wrong — but it's also not useful. This guide gives you the actual decision boundaries: what each cooling method handles, where it fails, and how to match your choice to your specific vehicle and duty cycle.
Why Cooling Is a System-Level DecisionThe cooling method isn't just a motor spec — it affects your entire drivetrain. It determines weight distribution, maintenance intervals, IP rating requirements, and total system cost over three to five years. Choosing based on motor specs alone is one of the most common ...
Update: We have created a new version of this library, which you can check here: Soil Moisture Sensor Library for Proteus V2.0.
Hi Friends! Hope you’re well today. I welcome you on board. In this tutorial, I’ll be discussing the Soil Moisture Sensor Library for Proteus. You won't find Soil Moisture Sensor Library in Proteus and we’re going to share its Proteus Library very first time. I have previously shared many Proteus Libraries for digital and analog sensors and today I’m discussing something new. Excited to get a hold of the Soil Moisture Sensor Library? Me too. In the upcoming days, I’ll keep sharing different libraries related to sensors. If you’re curious to sneak into the nitty-gritty of sensors not available in the Proteus library alre ...
Hello friends, I hope you all are doing great. In today's tutorial, I am gonna show you How to Optimize Your Projector for Maximum Quality. A dark room is the best place to make a quality presentation because it facilitates the production of bright images. However, it is not always the best place since your audience requires light to take notes, interact and see their neighbors. For this reason, you need to optimize your projector to produce maximum quality. You can increase your image quality by controlling the room`s ambient light and the projector`s light output. There are five tips that can help you optimize your projector`s output.
Set your Projector in Its Brightest Mode
Video and cinema modes often reduce your projector`s light output. Th ...
