Hello friends, I hope you all are doing great. Welcome to the 11th lecture of Section-III in the Raspberry Pi 4 Programming Series. In the previous tutorial, we discussed the interfacing of the Fingerprint sensor with Raspberry Pi 4. Today, we are going to discuss another sensor named the Pulse rate sensor and will interface it with Raspberry Pi 4.The field of healthcare monitoring has long been seen as a potential use
case for IoT i.e. examining the health
instead of regular checkups and local doctors. Using sensors,
your vital signs can be monitored and transmitted in real time, allowing
a physician on the other side or even an AI to analyze the data and
provide an accurate diagnosis. That does seem somewhat futuristic.
However, we are making steady progress in that direction ...
Hello everyone, hope you all are fine and having fun with your lives. In today's post, I am going to share How to generate PWM in 8051 Microcontroller. PWM is an abbreviation of Pulse Width Modulation and is used in many engineering projects. It is used in those engineering projects where you want an analog output. For example, you want to control the speed of your DC motor then you need a PWM pulse. Using PWM signal you can move your motor at any speed from 0 to its max speed. Similarly suppose you wanna dim your LED light, again you are gonna use PWM pulse. So, in short, it has numerous uses. If you are working on Arduino then you should read How to use Arduino PWM Pins.
PWM, as the name suggests, is simply a pulse width modulation. We take a pu ...
Hello friend. In this article, I will cover essential points related to fluid kinematics, i.e., what fluid kinematics is and how the motion of the fluids can be explained without describing the forces acting on them. Further, I will explain Lagrangian and Euler about the motion of fluid and a lot more. So buckle up, and let’s start.
What is Fluid kinematics?
The definition of fluid kinematics is as follows:
Fluid kinematics is related to fluid motion without considering the forces responsible for the motion.
The following are some essential key points related to fluid kinematics:
The nature of fluid motion is categorized into two types: Lagrangian Euler.
I will extensively explain both types in upcoming topics.
The acceleration, velocity ...
Everyone is talking about Flutter, and if you are looking for Flutter developers for hire, you’ll know how competitive and difficult the recruitment process has become. It’s not surprising by any means. If you want to invest in app development, you have to hire Flutter developer - and quickly. This process will take time and careful planning on your part, but once you’ve assembled your dream team, you’ll realize that it was worth it. Large companies all around the world - including Netflix and Facebook - are using Flutter to successfully build their apps. It’s worth considering for your business or start-up.
In this step-by-step guide, we’ll look at all aspects of hiring Flutter app developers for your business, including interviewing, do’s and do ...
Hello everyone, I hope you all are doing great. Today, I am going to start this new series on ASP.NET Core and it's our first tutorial in this series. I will start from basics and will slowly move towards complex concepts. So, if you haven't worked on ASP.NET then you don't need to worry about that but you must have some basic knowledge of C# and object oriented programming.
I will use Visual Studio 2019 for these tutorials, it's community version is free to use and I will use C# language for developing ASP.NET Core web applications. So, let's first have a look at what is ASP.NET Core:
Introduction to ASP.NET Core
ASP.NET Core (originally deemed as ASP.NET xNext & was going to named as ASP.NET 5) is ...
Hello friends, I hope this article finds you happy, healthy, and content. Today, we are about to discuss one of the most commonly known types of transistors which you might have heard of many times when reading about transistors, the transistor under study is none other than the “Bipolar Junction Transistor’’, also known as BJT . In this article, we will go through the basics of the bipolar junction transistor including its meaning ,definition, types, characteristics, and applications. So, let's get started.
Definition of BJT
A BJT in its full form is written as bipolar junction transistor and we can define it as,
"A bipolar junction transistor is a three-terminal semiconductor device which is made up of two PN junctions within its structure a ...
Traditional concrete can develop cracks through recurring freeze-thaw cycles over time. Cracks expand as it freezes, potentially letting water seep in further pulling it apart. Just as concrete deteriorates, steel structures do too due to inevitable corrosion. The rusted steel eventually wears the entire structure, threatening a crash if not inspected by a safety engineer. Innovations in building materials are rapidly disarming hazards posed by old materials—a British steel company patented a new form of colour-coated steel, galvanized steel, being used as additional protection against adverse environmental factors. Read more here.
Researchers have pondered whether materials could be made as such to bounce back from harsh conditions and vulnerab ...
Hi Friends! Hope you are doing well. In this platform we mainly cover information related to engineering and technology, no matter if you are a newbie or experts, you'll find something handy that may resonate with your field of interest. Today, I'll unlock the details on the Introduction to PIC18F4520. It is an 8-bit enhanced flash PIC microcontroller that comes with nanoWatt technology and is based on RISC architecture. Many electronic applications house this controller and cover wide areas ranging from home appliances, industrial automation, security system and end-user products.
This microcontroller has made a renowned place in the market and becomes a major concern for university students for designing their projects, setting them free from t ...
Carbon monoxide is produced whenever combustion is incomplete, and its hazard comes as much from its invisibility as from its chemistry. OSHA sets the permissible exposure limit at 50 ppm as an 8-hour time-weighted average, with a ceiling of 200 ppm. NIOSH places the immediately dangerous to life or health threshold at 1,200 ppm — a concentration that can be reached within minutes in a poorly ventilated enclosed space. The gap between those two numbers is where industrial CO incidents tend to happen: slow enough that workers don't notice until symptoms appear, fast enough that there's little time to respond once a process goes wrong.
The case for fixed detection over portable monitoring comes down to one thing: fixed systems don't depend on human behavior. Portable detectors are appropria ...
Learning Management Systems have gained popularity with technological advancements.
The curiosity to learn NEW made the information available with just a few clicks away. That’s how e-learning was born!
Now, it has become inevitable for every business to adapt to the trend. When it involves developing a course from scratch, you need LMS.
Well, by what norms do we identify LMS vendors for my business?
Here are five checkpoints you should know when choosing an LMS vendor.
The background
It is quite common when you are choosing an LMS vendor; you look for the price. Beyond the quote they are offering, you need to verify their track record.
Ask the following questions to acquire the vendor’s level of the business.
