Hey readers! I hope you are doing good and learning something. Have you ever thought about electric vehicles, which are rechargeable and run on a battery? Now, it is possible, and today, we will discuss electric vehicles.
All over the globe, EVs have made a major difference by being a cleaner and cheaper way to travel than gasoline and diesel cars. Unlike cars with engines, electric cars are environmentally friendly because their engines use rechargeable batteries and give out no emissions. The rise in buyers and producers of EVs is thanks in part to new kinds of batteries, better motors, and certain actions taken by the government.
Because of their various operating systems, Battery Electric Vehicles (BEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Hybrid Electric Vehicles (HEVs), and ...
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, hope you are doing good and enjoying your life. Today, I am going to introduce you to Ethereum accounts. I have given you an introduction to blockchain in my previous tutorials, so let’s get started on the essentials of this technology. I am going to start with accounts.
Ethereum Accounts
An account is an important component of the Ethereum system.
It is the main building block and has a balance in ether (ETH) (Ethereum currency).
An account is capable of sending transactions on the Ethereum network.
The interactions between different accounts create transactions that are stored in the distributed database.
Each transaction involves the sender account, receiver account and contract account.
An account can be controlled b ...
Hey Guys! I hope you all are doing great. Today, I am going to give a detailed Introduction to Data types in C#. It's our 3rd tutorial in C# series & it's a theoretical tutorial so you just need to read it once.
I'll try to cover every aspect related to Data types in C# so you get a clear picture of what are data types and why we need them? So, let's get started with Introduction to Data types in C#:
Introduction to Data types in C#
Data Types in C# are used to inform the compiler about the type, size & nature of data that can be stored in a variable.
Whenever we need to declare a variable, we need to inform the compiler about the data size & type of the variable.
There are 3 types of data types available in C# programming, ...
Hey pals! Welcome to the next article where we're studying a gas sensor from the MQ sensor series. Today, we’ll understand the MQ-6 LPG butane gas sensor and will know the basic information about this product. This sensor has sensitivity for gases like LPG, isobutane propane etc and it is widely used to check any leakage of these gases. These are the commonly used gases but any leakage or excessive use may be harmful and even life-threatening. In such cases, sensors like MQ-6 are proved one of the most important devices.
In this article, we’ll start the discussion with the introduction of the MQ-6 LPG butane gas sensor. After that, we’ll move towards the datasheet of this product in which we’ll study the specifications, features, and some graphs that will show its working. After that, we ...
Hello everyone, I hope you are having a fine day. In today’s tutorial, I am going to discuss the if-else statement in JavaScript and what are conditional statements in detail.
In programming, while writing a program there may be an occasion where you need to adopt one out of a given set of paths. In such a case, you need to use conditional statements that allow your program to make the correct decision.
Conditional statements
Conditional statements are used to run a specific action based on the result of the different conditions (true or false). If the condition would be true one action would be performed and if the condition is false then another action would be performed.
A few examples of JavaScript conditional statements:
Verify the loca ...
Hi friends, I hope you are all well. Today we can talk about the dimensions of all physical quantities which include the base quantities and the derived quantities. Dimensions of physical quantities are the fundamental part that helps us understand the physical and natural properties of any physical quantity. In modern science and technology, in engineering, and in different fields of physics where physical quantities units are used, the dimensions of these units help to derive a new formula and are also used in derivations. Dimensions of physical quantities also convey the detail of the types of physical quantity.
Dimension of physical quantities also helps to check the correctness of the equation and the formula that we can derive or use to solve the problems. Dimension of the phy ...
Hello learners! I hope you are doing good. Today, we are learning about an important member of the gas sensor family, which is the MQ-2. When it comes to detecting or measuring smoke or gas, the MQ series gas sensors are widely used components in circuits. These sensors come with an operational amplitude comparator and a digital output pin therefore, they have applications in multiple fields of life. Mostly, it is used in Arduino projects where it senses the gas and the information is fed into the Arduino to allow the circuit to work according to its digital output.
In this article, we are going to discuss the basic introduction of this sensor in detail, along with the datasheet. Moreover, we’ll know its pinouts in detail and will see some important circuit diagrams. Moreover, we’ll try ...
Hello friends, i hope you all are fine and enjoying. Today i am going to share a new tutorial which is Interfacing Arduino with HC05 Bluetooth module. First of all lets have a little introduction about HC-05 Bluetooth module. HC-05 is a bluetooth module, which was designed for wireless data communication. This little module is capable of both sending and receiving data but it performs only one thing at a time, which means at a particular time it can only send or receive data but can't do the both tasks.
In order to send or to receive data, you have to make one module as a master and the other module as a slave. If both the modules are acting as master then, data will not transmit and if both the modules are acting as a slave then, again data will ...
Hey Geeks! Welcome to The Engineering Projects. We hope you are having a reproductive day. We know that sirens are the special sounds that are the symbol that something unusual is occurring or about to occur. You may have experienced the Siren of the Walkthrough Gates at the airport when a person having the knife or other forbidden material pass through it. Or you have heard the Siren of the ambulance and seen that all the traffic gives the way to the ambulance when they hear the special Siren of the Ambulance. The same is the case with the police Siren.
The Police sirens are the special sound and it is set with the help of 555 Timer Integrated Circuit. You will learn how can one design a Police siren using the 555 Timer circuit in this tutorial. ...
