Hello friends, I hope you all are performing well in your life. In today’s tutorial, we will have a look at detailed The Role of Search Engines in Our Society. this digital world, where the most advanced technologies are shaping our lives every day, search engines have become increasingly important for our everyday life. Search engines like Google are the first place where people go to find anything and everything they need.
From entertainment and fun to work, working, education, medicine, and more, search engines are our online universities and libraries of knowledge where people can get any information they need within mere seconds.
Then, there's also the fact that we're exposed to information anywhere we look or go. T-shirt slogans, traffic s ...
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 ...
Science, technology, engineering, and math are the foundations of our daily lives. They are the tools that professionals use to get things done and get them done right. That’s just one reason that STEM education is so important. Over the past few decades, a sea-change in educational theories has swept through academic institutions. Old ideas about a liberal arts education as a path to success have slowly been replaced by a growing determination to emphasize STEM education and encourage students to pursue STEM paths and STEM careers to develop the next generation of professionals.
In this article, we’ll look at some of the reasons that STEM education is so important. To do so, we’ll need to think about traditional education and why it’s now outdated ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention.
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32.
We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is the Current Source. In an electrical system, there are two main sources first one is a voltage source and the other one is the current source. There are further two types of current sources real and ideal current source. The current produced by the ideal current source has the same value irrespective the variation in the circuitry voltage. As the current of the ideal source does not depend on any parameter of circuitry like the voltage, resistance, so it also called independent source.
The current source is the correspondent of the voltage source. In today's post, we will have a look at its working, types, circuits, ideal sources and some other related fact ...
Hello everyone, I hope you all are fine and having fun. In today's tutorial, we are gonna have a look at How to add Button Control in VB database 2010. I have posted the first part of this tutorial few days ago in which I have shown that How to Create a Database in Microsoft Visual basic 2010. If you have missed that part then you can't understand the today's lecture. Today we will continue with the same application which we created in the last part and will add few new features in it.
Creating database is difficult but adding features in it is very easy job and its also a must requirement of the application because user wants an easy control of application. So in order to make the application user friendly its necessary to add few features ...
Hello students! I hope you are doing great. Today, we are talking about the decoders in the proteus. We know that decoders are the building blocks of any digital electronic device. These electronic circuits are used for different purposes, such as memory addressing, signal demultiplexing, and control signal generation. These decoders have different types and we are discussing the 3 to 8 line decoders.
In this tutorial, we will start learning the basic concept of decoders. We’ll also understand what the 3-to-8line decoders are and how we connect this concept with the 74LS138 IC in proteus. We’ll discuss this IC in detail and use it in the project to present the detailed work.
What is a 3 to 8 Line Decoder?
A three to eight line decoder is an electronic device that takes three inputs and ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to BC547. It is an NPN bipolar junction transistor (BJT), mainly used for switching and current amplification.
Its maximum current gain is around 800. So, let's have a detailed overview of BC 547.
Introduction to BC547
BC547 is a 3-Terminal NPN Bipolar Junction Transistor(BJT), mostly used for switching purposes and current amplification.
BC547 Pins(Terminals) from left to right are called:
Collector.
Base.
Emitter.
Depending on the voltage applied at Base Terminal, BC547 can operate in two states, named:
Forward Biased.
Reverse Biased.
BC547 as Reverse Bias ...
Hello Everyone! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to CD4035.The CD4035 is a shift register that is mainly used in counters, control circuits, and registers. It contains clocked signal serial chip that is a four-stage register. Synchronous Parallel inputs are provided to each stage and serial inputs are offered to the first stage via JK logic.
I suggest you read this post all the way through as I’ll detail the complete introduction to CD4035 covering datasheet, pinout, features, alternatives, and applications. Let’s jump right in.

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
