Data science is a rapidly growing field that is revolutionizing the way businesses and organizations operate. With the explosion of data in recent years, there is a high demand for professionals who can analyze, interpret, and make decisions based on large amounts of complex data. Pursuing a degree in data science can provide you with a variety of benefits, including high-demand job opportunities, diverse skill sets, strong problem-solving skills, interdisciplinary learning, and the ability to innovate. Some of the key benefits are explained below.
High Demand
Obtaining a degree in data science is a smart career move, especially considering the high demand for qualified professionals in this rapidly growing industry. One of the most significant b ...
PWM stands for Pulse-Width Modulation. Once the switching frequency (fsw) has been chosen, the ratio between the switch-on time (TON) and the switch-off time (TOFF) is varied. This is commonly called duty-cycle (D). The duty cycle can be between 0 and 1 and is generally expressed as a percentage (%).
D = TON / (TON + TOFF) = TON x fsw
The variation of the pulse width, made at a high frequency (kHz), is perceived as continuous and can be translated into a variation of the rotation speed of a motor, dimming a LED, driving an encoder, driving power conversion, and etc. The use of PWM is also widely used in the automotive sector in electronic control units (ECU - Electronic Control Unit) to manage the energy to be supplied to some actuators, both fix ...
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 friends, hope you all are fine and having fun with your lives. Today's post is about Interfacing of LCD with 8051 Microcontroller. In my previous post, we have seen How to do Serial Communication with 8051 Microcontroller, which was quite a basic tutorial and doesn't need much hardware attached to it. Now today we are gonna have a look at Interfacing of LCD with 8051 Microcontroller. LCD is always the basic step towards learning embedded as it serves as a great debugging tool for engineering projects.
LCD is also used almost in every Engineering Project for displaying different values. For example, if you have used the ATM machine, which you must have, then you have seen an LCD there displaying the options to select. Obviously that's quite a ...
Web scraping is an invaluable skill in today's data-driven world. However, it must be performed responsibly and efficiently for optimal results. Here are our top 9 best practices that promise smooth execution of your upcoming web scraping projects.
Setting the Stage: Understanding Basic Rules of Python-based Web Scraping
Diving into web scraping can be a truly exciting venture, but it's crucial you understand the basic rules first, and have a handle on Python itself
. Before coding your web scraping script in Python:Do enough research on the site or API you intend to scrape.Know what kind of data is available and how that data is structured.Analyzing websites also aids in understanding the HTML tags for effective extraction.Have clarity on wheth ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at Filters in ASP.NET MVC. It's our 9th tutorial in ASP.NET MVC series. It's also a new concept which is essential to discuss as it's used almost in every form submission.
We have already understand Controllers in ASP.NET MVC and we know that Controllers have action methods in it which are directly assigned to respective Views, which are then displayed to the user. But in some cases, we have to place some checks (called Filters) before or after this action method called. So, let's have a look at these Filters in ASP.NET MVC in detail:
Filters in ASP.NET MVC
Filters are attributes which we can use before or after action method called in a Controller.
C ...
Hello friends, I hope you all are doing great. Today, I am going to share the Raspberry Pi 4 Library for Proteus. In our previous tutorial, we shared the Raspberry Pi 3 Library for Proteus and as we mentioned in that tutorial, these Raspberry Pi libraries will have dummy modules i.e. We have just designed the exterior but these boards won't be able to read the Python code. Although just for fun, we have added the Arduino firmware in these boards, so we can upload the Arduino code in it. As the legends say, something is better than nothing. We have given these boards an unofficial name "Arduino Pi".You can use these Pi boards to design your circuit diagram or can also use it in your presentation/demonstration of your projects. I hope you will enjoy these simulated Raspberry Pi boards. Befor ...
Hello friends, I hope you all are having fun with your lives. In today's tutorial, we are gonna have a look at Action Selectors in ASP.NET MVC. It's the 11th tutorial in ASP.NET MVC series and if you have covered so far then that means you really want to learn this language. Action Selectors are also new for you as we haven't discussed them yet but they are not that difficult to understand.
Action Selectors are built-in attributes of ASP.NET which are directly applied to action methods of Controllers. We use Action Selectors to influence on Controller's action methods. In simple words, we use Action Selectors to guide URL Routers in selection of correct action method. Let's have a detailed overview of Action Selectors:
Action Selectors in ASP.NET ...
This is the next lesson in our Python course. Previously, we looked at an overview of the different data types in python such as dictionaries, Boolean and sets. This tutorial will focus on Python sets to get a deeper understanding of this data type, so let's get started. During your schooling, there is a good chance you learned about sets and set theory. Venn diagrams may even be familiar to you:
Don't worry if you don't recognize this! You should still be able to access this tutorial without any problems. Rigidly defining a set in mathematics can be both abstract and difficult to understand. A set is thought of as a well-defined group of unique objects, which are sometimes called "elements."
Python's built-in set type facilitates the grouping of ...
Welcome to chapter 9 of our python tutorial. In the previous chapter, we looked at frequent examples of invalid Python syntax and learned how to fix them. Up to this point, you are well aware of errors that may occur in your Python program and how you can solve them easily and quickly. Therefore, in this tutorial, we will look at a few more causes of syntax errors and zero-error divisions.
Mistaking Dictionary Syntax
As you learned before, omitting the comma from a dictionary element can result in a syntax error. In Python dictionaries, the equals symbol (=) is used instead of a colon to separate key and value pairs.
This error message is once again useless. In this case, the repeated line and caret come ...
