Hello Friends! I hope you all are doing well. Today, I am going to share with you a very basic and detailed tutorial on What is Chemistry? We will also discuss Chemistry types, popular Chemistry books, famous Chemists and their great inventions in the field of Chemistry etc. When you hear the word Chemistry, you may think, it is only concerned to the study of chemicals, dangerous substances etc. But let me surprise you, Chemistry is also known as the Central Science means it is the insight study of almost everything around us. I just remembered very comprehensive Chemistry definition by American Chemical Society, “Everything you touch, see, smell and hear involves Chemistry and chemicals”.
Scientist divided Physical sciences in 5 major discipline ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to design a Proteus Simulation for Automatic Plant Watering System using Arduino. We have designed this project for engineering students as it's a common semester project, especially in electrical, electronics and mechatronics engineering.
The two most significant hazards to the agriculture industry are the need for extensive labor and a scarcity of water. According to the World Wildlife Fund (WWF) organization, water shortages might affect two-thirds of the world's population by 2025, putting both the ecosystem and human health at risk. The use of automatic plant watering systems eliminates both of these problems by watering plants at specified times and amounts whil ...
Hello everyone, I hope you are having a good day. In today's tutorial, I am going to tell you about "Variables in JavaScript".
The topic, I am going to highlight today, is how to declare variables in JavaScript and types of Variable? JavaScript has variables too as many other programming languages, so let's get started with it:
What are Variables In JavaScript
Variable means anything that can vary(change). In JavaScript, Variable holds the data value, in simple words, JavaScript variables are containers and can store the data value. Variable in JavaScript are declared with var (reserved keyword).
It is the basic unit for holding or storing the data.
A variable value can change at any time.
Variable must have a unique name.
Syntax
var (Vari ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at what is difference between PCB and PCBA. The printed circuit board (PCB) is a circuitry board that used to construct engineering projects and electronic devices circuits. The invention of this board has reduced complicated wiring circuits that were used before its creation, the circuits manufactured by the complex wiring were very difficult to handle in sense of fault detection and reconstruction. The printed circuit board is manufactured by a substrate material that is constructed by material such as glass fibre, epoxy resins.
On this board, a large number of conductive paths are designed on which different symbols of electronic components are sketched so w ...
Hi Friends! I welcome you on board. Thank you for clicking this read. In this post today, I’ll document the Introduction to D13003K.
The D13003K is an NPN silicon transistor mainly employed for switching and amplification purposes. It comes with a power dissipation of around 50W which demonstrates the amount of energy this device releases during the functioning of this device. As this is an NPN transistor as here electrons are the major charge carriers. The collector current is 1.8A which means it can support load under 1.8A. The emitter-base voltage is 9V which means it needs 9V to bias this device and start the transistor action.
I suggest you read this post all the way through as I’ll walk you through the complete Introduction to D13003K covering pinout, datasheet, power ratings, ...
Hello friends, I hope you all are fine. Today, we are starting a new tutorials series on Ladder Logic Programming, used in PLC. It's our first tutorial in this series, so we are going to have a look at the detailed introduction to PLC and ladder logic. After welcoming every one of engineers, technicians, students, and hobbyists who have come to read this article willing to learn PLC programming, I would like to introduce one of the most used programming languages of PLC. The language we introduce here is a visualized language that connects and combines graphical symbols in logical flow same as the way we wire electrical circuits and that is the secret behind its simplicity not only in implementation but also in diagnosing problems.
Ladder Logic Pro ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a simple tutorial on Image zooming with bilinear Interpolation in MATLAB. We have seen many software in which there's an option of zooming an image. For example, if you have used paint or photoshop then you have seen that you can zoom your image quite easily by clicking a button. Today's we are gonna do the same thing but in MATLAB and we will have a look at the code behind this feature.
Now, when we are zooming some image then in fact we are increasing the pixels of that image and in order to do that we have to fill those extra pixels with the color of their neighbor pixel. This thing is know as interpolation. There are many different techniques for in ...
Hey Fellas! Hope you are enjoying life and getting most out of it. I am back to give you daily dose of information so you can excel and grow in your relevant field and keep coming back for what we have to offer. Today, I am going to uncover the details on the Introduction to 2n5457. It is an N Channel JFET (Junction Field Effect Transistor) which is mainly designed for audio and switching applications. It consists of drain, source and gate which are denoted by D, S and G respectively. I'll try to cover every aspect related to this transistor so you don't need to go any where and find all information in one place. Let's dive in and explore what is it about and what are its main applications.

ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on another ESP32 application in the field of IoT.
Hello readers, I hope you all are doing great. In the previous tutorial, we learned how to send sensor readings from ESP32 to the cloud (ThingSpeak webserver).
In this tutorial, we will learn to send HTTP POST requests from the ESP32 board to ThingSpeak and IFTTT APIs.
What is HTTP?
Fig. 1 Hypertext Transfer Protocol
HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text transfer protocol was invented alongside HTML (Hypertext markup language) to create the first interactive, text-based web browser: the original www or World Wid ...
