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 ...
Welcome back, guys! I hope you are well and having a great day. In today's tutorial, I will discuss the new topic "Basic Syntax and Rules in JavaScript".
Learning grammar for a spoken language is necessary before you start writing it. There are rules and regulations you have to follow to write. Similarly, all programming languages have their grammar/syntax and rules which you have to follow in order to execute.
JavaScript Is Case Sensitive
JavaScript is case sensitive programing language. Therefore variables, function names, language keywords and any other identifiers must have written with a consistent capitalization of letters.
Let me show you an example.
In this statement "alert" is case ...
Hi Guys! Glad to see you here. I welcome you on board. In this post today, I’ll be discussing Analog Vibration Sensor Library for Proteus. I have already shared the digital Vibration Sensor Library for Proteus, you should check that as well.
I’ve been adding brand new libraries for proteus covering sensors and Arduino boards. I’ve recently discussed Analog PIR Sensor Library for Proteus and Analog Flex Sensor Library for Proteus. You may be stuck into thinking I’ve previously shared those libraries but they were libraries covering digital PIR and digital Flex sensors, here we discussed analog libraries for both PIR and Flex sensors.
Before I pen down how to download and simulate Analog Vibration Sensor Library for Proteus, let’s discuss what is ...
Hello, I hope you all are doing well. In the previous tutorial, I shared a detailed introduction to JavaScript, where we discussed the basics. Today, I am going to tell you in detail How to Include Javascript Code in HTML Page and many more things that can help you understand JavaScript easily.
All right guys let's revise what we have learned in the past article, you saw me adding script & /script code at the bottom of the tags. Today, I will show you in detail what was the reason for adding the tags at the bottom and how can you add an external JS file. If you want to be an expert programmer, you should have a look at this Oracle Java Certification , it will surely excel your programming skills.
How to Include Javascript Code in HTML Page
We have two methods to include the JS ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP3055. TIP3055 is a silicon epitaxial-ignoble NPN transistor, which is assembled in TO-218 malleable parcels. It is the best device for power swapping circuits, parallel and series controllers (regulators), output phases and high power amplifiers. Its corresponding PNP transistor is TIP2955.
It is a universal device used in many industrial projects where audio amplification is required. Its structures are attractive much the identical excluding for the maximum power indulgence that is a slightly lesser. In today’s post, we will have a look at its fortification, smashup, prominence, proposals, etc. I will also share some links ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at a detailed Introduction to HC-12. It is a wireless data transmitter and receiver module, that uses 433 megahertz frequency and can communicate to one thousand meter distance. It can communicate with more than one microcontroller. This module operates from 3.2 volts to 5.5 volts.
This Bluetooth module is installed in industries to control different processes and machines. It is also used in the circuitry of different security systems. This module uses silicons LABs Si4463 for (radio-frequency) RF data transmission. In today's post, we will look at its working, features, pinout and applications in detail. So let's get started with Introduction to HC-12.
Introduction to HC-12
HC-12 is an RF mo ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at What is Bistable Multivibrator and how it can be used in different circuits. In this type of multivibrator, the circuitry can operate in any state according to a signal provided at its input while it does not happen in a monostable multivibrator. This arrangement is also defined as a flip flop because flip flop also operates at more than one condition. It also has the ability to store a single bit of information so it is mostly used in logic circuits and in computer data storage part.
This vibrator like other vibrators is used for the production of square waves with providing some delay. These circuits are constructed with numerous kinds of semiconductor components. The most used semiconductor dev ...
Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at What is Monostable Multivibrator. It is a simple electronic circuit, used to produce a pulse at its output also known as one shot. It generates output pulses according to corresponding circuitry requirements. Its main feature is that after the generation of the output pulse, it regains its stable state and does not produce any further output pulse till not triggers again.
This circuitry can be considered as a biased form of multivibrator (such circuitry that is used for implementation of 2-state modules like timers) that is (on) operating in the starting condition till the triggered point and then becomes unstable on its own. In today's post, we will have a look at its circuitry, construction, wor ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at detailed Introduction to Darlington Transistor. It was named "Darlington" as its inventor's name was Sidney Darlington, who was an electrical engineer and belonged to the United States of America. Such a circuit configuration that consists of 2 PNP or NPN transistor makes Darlington configurations. This transistor configuration is used for amplification and switching circuits.
The signal amplified by the first transistor also amplified by the second transistor & due to this two-time amplifications, this arrangement provides a high gain output signal. This transistor operation is similar to normal single transistor that has a base, emitter and collector. ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP122. It is a Darlington braces NPN transistor. It works like an ordinary NPN transistor, but as it consists of a Darlington pair it has a decent collector current assessment of nearby 5 amperes and it's gain is around 1000. This transistor can bear 100 volts around collector and emitter terminals due to this feature it can be used for high loads.
This is a common purpose transistor it used in different industrial projects. It manufactured for less time taking switching submissions. In today’s post, we will have a look at its protection, wreck, distinction, entitlements, etc. I will also share some links where I have connecte ...
