Introduction
Hello friends, I hope you are doing very well. Today we are going to learn and practice the master control reset (MCR)! So what is that MCR? Well! This is a tool you might use to control a group of devices with one push button for performing fast emergency responses with one click for a group of devices in one zone. In another word, you divide the program into zones and put this zone between a master control to control their operation as one unit by one contact. This technique is useful for applying emergence stops and also protecting some equipment by applying a safety restriction to not operate when that condition is in effect.
The concept of the master control reset (MCR)

Hello friends, I hope you all are doing great. Today, I am going to share the 6th lecture in the Raspberry Pi 4 Programming series. We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. In today's guide, I'll show you how to interface a 16x2 LCD screen with Raspberry Pi 4.
So, let's get started:Interface LCD 16x2 with Raspberry Pi 4Today, we are going to interface a 16x2 LCD screen with Raspberry Pi 4. At first, we will print the "Hello World" text on the LCD, and in the last section, we will implement the scrolling and blinking of text on the LCD.Here's the video tutorial on LCD interfacing with Raspberry Pi 4:Components RequiredWe will need the following components for today's project:Raspberry Pi 4.M ...
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 ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a project named as DTMF Decoder using MATLAB. In this project, I have designed a keypad in MATLAB using the GUI functionality of MATLAB. After designing the keypad, I have assigned a tune to each of these buttons. Obviously the tune attached to each button is different and when we press any of these buttons, then the MATLAB recognizes the respective button.
This project is designed in MATLAB and I have tested it on MATLAB 2009 and MATLAB 2014 and it works fine on both of them. Code is given below in this tutorial for download. f you got problem in it then ask in comments and I will try to resolve them. So, let's get started with DTMF decoder in MATLAB.

Although 3D printing feels like a relatively new development, there are lots of promising projects underway. A scheme to build 46 eco-homes has been approved in the UK’s first 3D printed development
, for example, and the same is happening in Australia to provide housing for remote indigenous communities in rural areas
.
But how can 3D printing be applied in business? Here’s a breakdown on how it can be used and the opportunities it creates.
What is 3D printing?
3D printing refers to technology that can form materials using computer designs. The earliest signs of 3D printing came about in 1981. Dr. Hideo Kodama created a rapid prototyping machine that built solid parts using a resin and a layer-by-layer system.
Using a bottom-up technique, the material is layered until a tangib ...
Hello everyone, I hope you all are fine and having fun with your lives. Today's topic is about the Evolution of Capacitors and I have tried my best to explore all about Capacitors. A Capacitor is one of the passive elements. It is a two-terminal electrical component. It stores energy in the form of an electric field. The physical appearance of the practical capacitors varies depending upon their usages. The basic capacitor has two electrical conductors that are separated by a dielectric. The material used in electrical conductors is a conductive electrolyte, thin films, sintered beads of metal and thin foils. And, the material used in the dielectric is plastic, glass, ceramic, Vacuum, mica, paper, oxide layers, etc. A capacitor is also called a con ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about How to Reset Arduino Programmatically. Sounds a bit weird, yes it is :) but literally in some cases, this technique is the only choice you have. It recently happened to me in one of my projects, that's why I know How important it is. Before going into details, let's first have a look at the resetting feature of Arduino.
If you have worked on any Arduino board, then you must have noticed the RESET pin in Arduino and you may wonder what's the use of this pin. So, today this pin is gonna get useful. Moreover, you have also noticed that when you upload the code to your Arduino board then the Arduino resets, another way of resetting Arduino is by opening the Seri ...
Hello friends, hope you all are fine. In today's project, we are gonna design Electronic Quiz Project with 8051 Microcontroller. I have done this project recently in which we need to design a quiz project game using 8051 Microcontroller. It was quite a big project and we have to work quite hard to make it done. In this project we have used many components on which I have already post tutorials so that you guys first get introduction to those components. So, first of all you should read Interfacing of LCD with 8051 Microcontroller, after that you must check Interfacing of Keypad with 8051 Microcontroller and finally get your hands on Serial communication with 8051 Microcontroller. These tutorial are must to read because these are all gonna use in t ...
The eCommerce industry, which has already experienced year-over-growth for the past five years, gained a monumental boost after the pandemic made online shopping mainstream. Today, there are more than 20 million eCommerce businesses operating worldwide, and new companies open shops every day.
The majority of these companies need skilled developers and engineers to build safe and robust eCommerce sites to house their businesses. If you are interested in specializing in eCommerce development, you would be remiss to ignore the advantages and disadvantages of each payment gateway option.
Payment gateways allow online customers to purchase products seamlessly and securely. However, they are not all created equal. As an engineer or site developer, you s ...
The digital industry is evolving day by day. Today, computers and phones are no longer heavy. They are sleek, powerful, and very light. Actually, some smartphones are more powerful than laptops. All this is possible because of the miniaturization of the electronic gadgets' printed circuit boards (PCBs).
Printed Circuit Boards or PCBs are categorized into several types based on design specifications, manufacturing processes, and application requirements. They are used in various sectors such as automotive, medical, defense, and other areas, you can learn more information at PadPCB.
Before you select a PCB, there are several factors you need to consider. Moreover, it is essential to seek advice from professionals. Although there are several types of ...
