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 ...
We've all heard that clicking on links or attachments can lead to identity theft of sensitive, personal information. And while it's true - if you're not careful, you could be leaving yourself open to hackers and other dangers. But what most people might not know is the difference between "hacking" and "data theft". In this post, we outline the steps data security engineers recommend you take to protect yourself from these different types of threats.
What do data security engineers recommend for people who don't work in security?
Data security engineers are not your everyday IT professionals, so what do they recommend for parts of the population who aren't working in IT?

Hello learners! Welcome to the next episode of the arrays, in which we are moving towards the details of the arrays at an advanced level. In the previous lecture, we covered the introductions and fundamentals of arrays, dimensional arrays, and array operations. One must know that the working of the arrays does not end with simple operations, and there is a lot to learn about them. Arrays and their types are important topics in programming, and if we talk about Python, the working and concepts of the array in Python are relatively simple and more effective. The details of the advanced types of arrays will prove this statement. We have a lot of data to share with you, and for this reason, we have arranged this lecture. It is important to understand the reasons behind the reading of this lect ...
Hello friends, I hope you all are ding great. In today's tutorial, I am going to show you How to use Arithmetic Operators in Python. It's our fourth tutorial in Python series. Arithmetic operators are required in mathematical problem solving.
We will first have a look at the arithmetic operators and after that, we also discuss different builtin arithmetic functions in Python Math module. So, let's get started:
Arithmetic Operators in Python
Arithmetic operators ( +, -, *, /, ^ etc. ) are used to perform simple arithmetic operations in python.
So, let's open up your PyCharm and perform a simple task using these operators, as shown in below figure:
I used a single star for multiplication and a doub ...
Our next step in the Raspberry Pi training program is to get zero tiers up and run on a Raspberry Pi 4. How to utilize a Raspberry Pi to measure internet speed and store the results in Grafana or Onedrive was the topic of the last piece. During the project, you will discover how to install ZeroTier on a Raspberry Pi and get it up and running. We will also learn how to set up a firewall to secure our network.
Components
Raspberry pi 4
Power supply
Ethernet or wifi
What is zeroTier
ZeroTier is a software that provides a streamlined web-based interface for constructing virtual networks connecting various gadgets. Somewhat akin to configuring a virtual private network on a Raspberry Pi, these networks exist only in cyberspace. The process o ...
Welcome to the tenth lesson of our python course. In the previous tutorial, you learned about syntax errors in Python, and in this lesson, we will look at one more error notice that is given by Python when there is an error in your code. So, without further ado, let's get started.
Any time an exception is thrown in your code, Python shows you the stack trace. If you don't know what the traceback output is showing you, it can be a little overwhelming. Python's traceback, on the other hand, provides a goldmine of information that can assist you in figuring out why an exception was triggered in your code and fix it. It's essential to learn how to use Python traceback to become a better coder.

Cryptocurrency trading is a popular way to get started with cryptocurrency. It's also a great way to multiply your funds if you're an experienced trader. In this post, we'll give you the basics of how cryptocurrency exchanges work and help you choose an exchange.
What is Cryptocurrency Trading?
Cryptocurrency trading is the process of buying and selling cryptocurrency on an exchange. Cryptocurrencies are digital assets that can be exchanged for other cryptocurrencies, for example, you can exchange eth for sol
, or for fiat currency (US dollars).
You can use a cryptocurrency exchange to trade your coins, or you can buy them directly from another person. Some exchanges offer both options: they allow users who want to trade coins with one another and also serve as platforms where people ...
Welcome to the next tutorial of our Raspberry Pi programming course. In our previous tutorial, we learned how to create a timelapse video with still images and understand how phototimer and FFmpeg work. In this lesson, you'll make a button-controlled "music box" that plays different sounds depending on which buttons are pressed.
What you will learn
Connect button pushes to function calls using the Python gpiozero package and uses the Python dictionary data structure
Components
Raspberry Pi
Breadboard
Buttons
Jumper wires
Speaker
Set up your project
For this project, you'll need some audio samples. On Raspbian, there are many audio files; however, playing them with Python can be challenging. You can, however, transform the audio files ...
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 Python programmers! Welcome to the engineering projects where you will find the best learning data in a precise way. We are dealing with Python nowadays, and today, the topic of discussion is the arrays in the language. We have seen different data types in Python and discussed a lot about them in detail till now. In the previous lecture, we saw the details of the procedures in dictionaries. There are certain ways to store the data in the different types of sequences, and we have highlighted a lot about almost all of them. It is time to discuss the arrays, but before this, it is better to understand the objectives of this lecture:
Introduction to arrays
Difference between contiguous and non-contiguous memory locations
One-dimensional arrays
Functions in arrays
What are Arra ...
