Hello friends, hope you all are fine and having fun with your lives.In today's post, we are gonna see How to use timer interrupt in 8051 Microcontroller.8051 Microcontroller comes with timer as well. They normally have two timer in them named as Timer0 and Timer1. These timers are used for counting purposes like you want to start some countdown in your project then you can use these timers or you wanna create some clock then in that case as well you need timers. So, in short there are numerous uses of timers in a project. Timers are also used for delays like you wanna create some delay of 10 sec but you dont wanna use the delay function in your project so you can use timers. You start the timer and then when it comes to 10 seconds then you can do ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4. This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work.
What is time-lapse?
When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras.
Components
Raspberry pi 4B
Pi camera
Connect to the Raspberry Pi
Cameras that can be used with the Raspberry Pi are a bit limi ...
Welcome to the next tutorial on our raspberry pi four python programming. In the previous article, we built a system that recognizes when two people are in physical contact using OpenCV and a Raspberry Pi 4. We used the weights from the YOLO version 3 Object Recognition Algorithm to implement the Deep Neural Networks part. Regarding image processing, the Raspberry Pi consistently comes out on top compared to other controllers. A facial recognition program was among the earlier attempts to use Raspberry Pi for sophisticated picture processing. In today's world of cutting-edge technology, digital image processing has expanded rapidly to become an integral feature of many portable electronic gadgets.
Digital image processing is widely used for such t ...
Greetings! This is the complete project of our Raspberry Pi 4 tutorials. In our previous tutorial, we learned to set up our raspberry pi as a virtual private network server. In this tutorial, we will design a smart attendance system using an RFID card reader, which we will use to sign in students in attendance in a class.
First, we will design a database for our website, then we will design the RFID circuit for scanning the student cards and displaying present students on the webpage, and finally, we will design the website that we will use to display the attendees of a class.
Components
RFID card kit
Breadboard
Jumper wires

I2C LCD screen
Design a database in MySQL server
Additionally, the Database server offers a DBMS ...
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 ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create a Custom Filter in ASP.NET MVC. It's our 10th tutorial in ASP.NET MVC series. In our previous tutorial, we have cleared our concepts about Filters in ASP.NETMVC and we have also implemented one built-in filter of ASP.NET MVC.
Now, its time to have a look at How to Create a Custom Filter in ASP.NET MVC, in which you can specify your own authentications or handling etc. In our ASP.NET applications, we have use custom built filters a lot for different purposes. So, let's have a look at How to Create a Custom Filter in ASP.NET MVC:
Create a Custom Filter in ASP.NET MVC
In ASP.NET MVC, custom filters are handled by a base class named as ActionFil ...
Hey learners! Welcome to the following lecture on Python, where all the examples are practically explained with the help of the Jupyter notebook. We have been working with the data types for a long time, and now we know all the basics about them. There are certain concepts that are applicable to almost all sequences, but there are some rules for performing this function. Python has many concepts that are unique and simple, and if we talk about the slicing of the data type, other high-level languages such as C++ have the same concept, but Python gives the easiest way to do so. How we will work on different data types to check whether they support the slicing or not. In this way, we can revise the concept that we have been working on so far. Nevertheless, before that, you have to check the l ...
Hey peeps! Welcome to the new tutorial for the Python programming language, where we are at the point where we are going to learn about the loops. Loops are fundamental concepts in programming, and if we talk about Python, there is a smaller variety of loops in it, but the most important ones are available to practice in Python. In the last session, there was a long discussion about the while loop in detail. We had seen some examples and the details of the statements that can be used within the while loop. In the present lecture, we are going to discuss the second type of loop in Python, that is, the for loop. You will go through the training of every important and basic step about this loop, but first of all, you have to look at the basic list:
Why do we prefer for loop over some other c ...
Hello friends, I hope you all are doing great. This is the 7th lesson of our Python tutorial. We were introduced to Python numbers in the previous chapter and learned how they are utilized with expressions, so we have a good understanding of math operations.
We'll go over a couple more arithmetic functions and complex numbers in this lesson. I will try my best to keep it simple. Let's get started!
Python round function
You can work with numbers in Python using a few built-in functions. Three of the most common will be discussed in this section:
Rounding to a specific number of decimal places can be done with round().
abs(), which returns a number's absolute value.
pow(), which raises a number to a ...
Welcome to chapter 6 of our python course. Previously, we introduced integers and saw how they may be combined with strings and stored in variables. Today, we'll take a closer look at the python number types and how they're stored in variables to see what actions are possible.
What you'll learn in this tutorial is how to:
Add, subtract, multiply, and divide numbers.
Work with modular.
Use exponents.
Use expressions.
Use a predetermined number of decimal places to round numbers
Use strings to format and show numeric data.
With this in mind, let`s start.
How are integers created?
Integers can be created by simply inputting a number. For example, the tutorial variable is assigned the integer 6 in the following way:
