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 readers! Welcome to the easiest explanation of the current divider circuit. I hope you are doing well. In electrical and electronic circuits, the current distribution among different components and branches is the fundamental concept and it must be crystal clear in mind to understand the circuit working. One key concept that helps to understand this flow is the current divider rule, which is purely related to the parallel circuits. It is the method of determining electrical current flow into multiple paths of the parallel connection circuit.
Today, we’ll shed light on the basic introduction of the current divider and the discussion will start from scratch. You’ll see the basic concepts of the circuits, working, derivation, and applications of the current divider in the circuit. Mo ...
Hello friends, I hope you all are well and doing great in your lives. In today's tutorial, I am going to share the Introduction to Inverters. An inverter converts DC voltage or current to AC voltage or current. You can also say that it transfers or converts power from a DC source to an AC load. The aim of this circuit is to supply AC power similar to the one that we receive at homes.
Firstly, I am going to share some basic information related to inverters. In the second section, I will give you the basic configuration or parts of it and in the last section, I will tell you the types and applications. Let's now get started with the Introduction to Inverters:
Introduction to Inverters
An inverter is connected to a DC source and it converts it in ...
Product-development cycles keep speeding up, parts supply chains feel tighter than ever, and regulatory gates are multiplying. Picking the right product-lifecycle-management (PLM) backbone in 2026 is no longer a back-office IT decision—it is mission-critical engineering infrastructure.
The global PLM market hit USD 27.88 billion in 2025 and is on pace to reach USD 53.74 billion by 2034 (7.7% CAGR). The good news: the tool landscape has never been richer. The bad news: feature sheets all sound identical if you do not know where to look.
Below is an engineer-focused shortlist of the six best PLM software for hardware teams most likely to survive a hard-nosed technical evaluation this year. We scored each option on speed to deploy, out-of-the-box integrations, cost to scale, AI automation, ...
Hey everyone how are you, hope you are doing great. In this article I will guide you about the C# comboBox. In my previous article, I have explained about C# button control and their features. C# ComboBox is quite similar to button control but its major properties are different. The combo box can hold multiple values at the same time, it's like drop-down box in appearance and you can select any value inside it. Most of the time, combo box is used to give the user multiple selection options. But in signup forms, it's used for country selection where you have to select your country from drop down. You can use combo box according to your requirements.
You can add the combo box from the toolbar and drag it on the form. When you drag that you can set t ...
Deep learning is an important subfield of artificial intelligence and we have been working on the modern neural network in our previous tutorials. Today, we are learning the transformer architecture neural network in deep learning. These neural networks have been gaining popularity because they have been used in multiple fields of artificial intelligence and related applications.
In this article, we will discuss the basic introduction of TNNs and will learn about the encoder and decoders in the structure of TNNs. After that, we will see some important features and applications of this neural network. So let’s get started.
What are Transformer Neural Networks
Transformer neural networks (TNNs) were first introduced in 2017. Vaswani et al. h ...
Most hardware engineering teams hit the same wall at the same point in a project. The CAD model is ready. The BOM is locked. Firmware is running on a dev board. Then comes the mechanical work: a test fixture, an aluminium housing, a custom bracket — and suddenly the question of how to actually get that part made becomes the blocker.Designing for manufacture is covered in textbooks. Finding a reliable shop to make your part on schedule, at the right tolerance, and without requiring a procurement department behind you is not. That gap is where a lot of prototype-to-production timelines fall apart.This article covers what hardware and mechanical engineers need to understand about the practical realities of sourcing CNC milled components — particularly from China, where the majority of high-vo ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new tutorial which is Interfacing of Flame Sensor with Arduino. I have recently posted a tutorial in which I have shared the Flame Sensor Library for Proteus. Now in this tutorial, I am gonna use that Flame Sensor Library and will interface this Flame Sensor with Arduino. So, if you haven't downloaded this file then I suggest you to download this Flame Sensor Library so that you can easily simulate this flame Sensor in Proteus.
I am sharing interfacing of this Flame Sensor with Arduino today, but soon I will also post a tutorial on Interfacing of Flame Sensor with PIC Microcontroller. If you guys have any questions then ask in comments. I have also ...
Hi Guys! We always keep on working to find useful ways that give you quick and economical solutions to your needs. Today, I am going to give a quick review about WellPCB and why you prefer them if you intend to making high quality PCBs with reasonable price.
Where there is a need of electronic devices, there is a need of PCB. Joining number of components on board using old conventional with end to wiring is becoming obsolete that happened to cover more space, carry heavy weight and turned out to be expensive with the ability to performing less number of functions. This led to the introduction to printed circuit board.

PCB is an integral part of most of the electronic devices, specially when you are looking to make som ...
Hey guys! I hope you are doing good and having fun. Today, I am going to unlock the details on the Introduction to Resistors. Resistor is a two terminal component that is used to restrict the flow of current. Resistors are widely used in electrical circuits. They come in different forms ranging from variable resistors to fixed resistors. Depending on the feature of resistors, both are used in many applications. I am going to cover all aspects relating to resistors. Let's get started.
Introduction to Resistors
A resistor is a two-terminal device that is used to resist the flow of current. It is one of the most commonly used components in electrical circuits.
Resistance of any resister is described in ohms. Ohm is denoted by the Greek letter om ...
