Hello everyone, I hope you all are doing great. In today's tutorial, we will have a look at the Air Conditioning revolution brought by HVAC. Air conditioning is a mainstream engineering wonder, and much of the world relies on their HVAC for comfort and day-to-day living. Unfortunately, as a study in the Journal of Energy and Buildings found, HVAC systems come with a high environmental cost amounting to 40% of energy consumption in all residential sectors. This comes chiefly from heat transfer, but also from air cleaning processes and lost energy. Clearly, huge efficiencies need to be found in the HVAC/air conditioning sector – and innovation is providing.
The air we breathe
A large component of the inefficiency of HVAC is through the air filtration ...
Hey pupils, Welcome to another lecture of this series on signals and systems, and this is the time to learn an interesting topic in which you are going to learn about the convolution of the signals. In the previous sessions, we have learned basic operations on the signals, and this time, you are going to know the convolution of the signals and different criteria that are related to this topic. Have a quick view of the concepts that will be clarified in this lecture: What is convolution? What are some basic types of convolution? How can you define the properties of linear convolution? How can you implement convolution in MATLAB using function and without function? What is the difference between linear and circular convolution? What is the convolution of signals? Convolution is ...
Hi readers! I hope you’re having a great day and finding something thrilling. Imagine being able to solve a problem in seconds that would take the fastest supercomputers millennia, that is, quantum computing. Today, we will cover Quantum Computing.
Quantum computing is a relatively new technology that can present a new way of thinking about how information may be processed using the laws of quantum mechanics. Classical computing uses bits, which are either 0 or 1, while processing information, whereas quantum computing uses qubits and has the possibility of being a bunch of things at the same time by virtue known as the “superposition”. In addition to "superposition", qubits can be connected across space through a property known as "Entanglement", which allows quantum computers the potent ...
Hello readers, I hope you all are doing well. Welcome to the Section 2 (ESP32 Features) of the ESP32 Programming Series. ESP32 is equipped with numerous built-in features and in each chapter of this Section 2, we will explore one of these ESP32 features in detail.
In the previous Section(Section 1: ESP32 IDEs), we installed different software IDEs to program ESP32 boards. Among these IDEs, we are going to use Arduino IDE for programming ESP32. So, I hope all of your tools are configured properly and you are ready to explore the built-in features of ESP32.Today's the 1st Chapter of Section 2, and here we will discuss How to communicate with ESP32 Bluetooth Classic from a smartphone using Arduino IDE.
Here's the video tutorial for ESP32 Bluetooth Classic:
ESP32 Wireless Features ...
Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss What is Electromagnet. In 1820 physicist of Denmark Christian Orsted first time in the world found that the current produces the magnetic field. After four years of the Christian's theory in 1824 another physicist William Sturgeon who was United Kingdom native work on the findings of the Christian and created the electromagnet. It was created by the piece of iron whose design was like horse-show when the almost eighteen turns of the copper windings were rapped on the iron. The piece of iron was separated from the copper windings by insulation element.
After making these arrangements William Sturgeon connect the battery with the terminals of the copper windings, th ...
Hi Friends! Happy to see you here. I welcome you on board. In this post, I’ll walk you through the Introduction to BC639. BC639 is a high current gain bipolar junction transistor that falls under the NPN transistor family. It constitutes a high collector current and low collector-emitter saturation voltage and is widely used for amplification and switching purposes. It is used to drive load under 500mA. Collector Dissipation is 0.625W while DC Current Gain (hfe) ranges from - 40 to 160 with transition frequency 200MHz. In this post, I’m going to discuss all nitty-gritty of the BC639 transistor covering pinout, working, power ratings, alternatives, applications, and physical dimensions.

Hi readers! I believe you are doing fine and continuing to learn something new every day. This day marks the discussion about the diagnosis of a faulty MAP (Manifold Absolute Pressure). A MAP sensor is an important component in the engine management system of a vehicle, functioning to determine the absolute pressure inside the intake manifold and reporting back the real-time pressure to the Engine Control Unit (ECU), which then does the math to achieve an exact air-fuel mixture and timing of injection, allowing combustion to be smoother with all the variables at play and reduced emissions.
The MAP sensor detects the changes in air pressure inside the inlet manifold. The data relative to this pressure is used by the ECU to calculate fuel injection and ignition timing. The MAP sensor en ...
In the subject of electrical engineering, having precise calculations is essential to the process of creating systems that are both effective and safe. One such calculation that is extremely significant is called the voltage drop, it refers to the decrease in voltage that occurs when electric current flows through a circuit.
A great number of electrical engineers rely on a voltage drop calculator
to ensure that the circuits they design match the necessary criteria. This page provides an overview of the many approaches to calculating voltage drop, making it simpler for engineers to select the strategy that is most suited to their individual projects.
Voltage Drop Formula:
It is vital to have a solid understanding of the voltage drop formula before moving on to the automated approaches. ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to show you Why Vulnerable Chrome Extensions are a Cybersecurity Threat. It is probably no surprise that the majority of Google Chrome users have some kind of add-on or extension installed on their browser. Why? Chrome extensions are convenient and easy to use. However, what most fail to notice are the vulnerabilities that can leave users’ devices exposed to security risks. We’ll dig deeper into the benefits of finding the right VPN Chrome solution to avoid cybersecurity threats.
While certain Chrome extensions are safe to use, some of them are designed for malicious purposes such as data theft and unauthorized access. The bad news is, we can never be 100% certain whe ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to combine all of my previous tutorials for LCD Interfacing with Microcontrollers, at a single platform for your easiness. You will able to see and learn the interfacing of LCD with three different microcontrollers. Before going into any detail I would like to tell you a bit about the history of LCD. There are a lot of devices in the market now a days, which can be used as the displaying devices. LCD's are also among those devices and considered as the one of the most important devices specially for the microcontroller based projects. The word LCD is basically abbreviated from Liquid Crystal Display because it is made up of Liquid Crystal Technology. LCD is a ...
