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 ...
Hey, everyone, hope you are doing great. In today's article, we are going to explore C# Checked ListBox Control. In the previous article, we discussed in details about C# TextBox, C# Label, C# ListBox, C# ComboxBox and C# Button. C# Checked ListBox plays very important role in Point Of Sale applications. In some words, we can say this is a combination of check boxes and list. C# Checked ListBox is used to gain specific information from end-user. It's mostly used in survey-based application to gain the voting for a specific purpose.
We will work with Checked ListBox same as we have worked with ListBox & ComboBox. You can use C# Checked ListBox for multiple purposes. You can use this as the attendance taker to mark the attendance of students.
C# ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create ViewModels in ASP.NET Core. It's our 9th tutorial in ASP.Net Core series. We have already covered Controllers, Models & Views in our previous lectures and now it's time to understand this fourth pillar of MVC architecture.
ViewModel is not an integral part of MVC architecture and can be ignored in simple projects but in complex applications, we have to use ViewModel as it adds flexibility in the project. So, let's have a look at ViewModels in ASP.NET Core:
ViewModels in ASP.NET Core
ViewModels in ASP.NET Core ( also called Data Transfer Objects [DTO] ) are used to send Models data from Controll ...
Hello! Welcome to the next lesson in this Python course. In the last session, we learned about python tracebacks and how to deal with them. A dictionary, like a list, is a collection of items, and we'll look at that in this tutorial as well.
What will you learn?
This tutorial introduces you to the fundamentals of dictionaries in Python and teaches you how to work with dictionary data. After reading this article, you should be able to tell when and how to utilize a dictionary as a data type.
Characteristics of Dictionaries and lists
Both can be changed (mutability).
A dynamic relationship exists between them. When needed, they're able to expand and contract.
Both are nestable. Another list can be ...
Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we implemented a speech recognition system using raspberry pi and used it in our game project. We also learned the fundamentals of speech recognition and later built a game that used the user's voice to play. However, this tutorial will integrate a real-time clock with our raspberry pi four and use it to build a digital clock. First, we will learn the fundamentals of the RTC module and how it works, then we will build a digital clock in python3. With the help of a library, we'll demonstrate how to integrate an RTC DS3231 chip with Pi 4 to keep time.
Real-Time Clocks: What Are They?
RTCs are clock units, as the name ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hello friends, I hope you all are having fun. In today's tutorial, we are going to have a look at How to handle Static Files in ASP.NET Core. It's our 4th tutorial in ASP.NET Core series. If you inspect your localhost page displaying Hello World, then you will see that there isn't any HTML code in it. Instead, it's just displaying Hello World in text format.
In today's tutorial, we will have a look at How to add HTML, JavaScript, CSS or any other static file in ASP.NET Core. In our previous tutorial, we have discussed Middleware in ASP.NET Core, so if you haven't studied that then have a look at it first, as we are gonna use some new middleware components today. So, let's get started:
How to handle Static Files in ASP.NET Core
By default, ASP.N ...
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 ...
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 ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to configure our raspberry pi for voice control. We also discussed some methods of reducing vexing noises so that the voice command program understands you. However, in this lesson, we will learn how to tweet from Raspberry pi.
What will we learn?
Assume you wish to add tweeting into a Raspberry Pi software you're developing. This article will show you how to build a Twitter app, get access privilege tokens, and post a tweet. On our Raspberry Pi, we'll make a simple program that tweets the result of the uptime command. This is a made-up example, but it demonstrates what is needed to tweet from a raspberry pi.
For this session, a repo has been set up. Because we'll be referring to code wit ...
