Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to HC-SR501. HC-SR501 is a motion detector sensor, that uses infrared waves for the detection of an object. It is an automatic control device, and also has large sensitivity and high reliability. It is used in auto-sensing control devices, where we need to perform motion detection.
HC-SR501 is used in industrial projects and buildings for security purposes. In today's post, we will have a look at its pinout, working, protocol, circuit diagram, etc. I will also share some links to projects where I have interfaced it with Arduino and some other microcontrollers. Friends if you have any questions please ask in the comments I will try my best to solve your problems and I w ...
Hi Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll discuss how to calculate PCB trace width?
The PCB (printed circuit board) is a mechanical layout that electrically connects different components on the board using conductive copper traces that maintained current throughout the circuit board. Different electrical components are placed on the non-conductive substrate which are soldered from the other side of the board. On the non-conductive side of the board copper traces electrically connect these components.
Earlier end-to-end wiring was used in place of PCB boards but now it’s become obsolete. Needless to say, PCB has revolutionized the modern electronics that are precise and com ...
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on another ESP32 application in the field of IoT.
Hello readers, I hope you all are doing great. In the previous tutorial, we learned how to send sensor readings from ESP32 to the cloud (ThingSpeak webserver).
In this tutorial, we will learn to send HTTP POST requests from the ESP32 board to ThingSpeak and IFTTT APIs.
What is HTTP?
Fig. 1 Hypertext Transfer Protocol
HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text transfer protocol was invented alongside HTML (Hypertext markup language) to create the first interactive, text-based web browser: the original www or World Wid ...
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, ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to MAX30100. MAX30100 is a heart pulse rate monitor sensor. This sensor consists of two Light Emitting Diodes (LEDs), (one emits infrared light and the other emits red light) modifiable optics, low noise signal processor that detects heart pulse rate signal. Its operating voltage is from 1.8v to 3.3v.
The MAX30100 is used in different industrial and medical equipment such as fitness measurement devices, medical devices, and different wearable instruments. In today's post, we will have a look at its working, pinout, protocol, features, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have any questions about it please ask ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create a Custom Filter in ASP.NET MVC. It's our 10th tutorial in ASP.NET MVC series. In our previous tutorial, we have cleared our concepts about Filters in ASP.NETMVC and we have also implemented one built-in filter of ASP.NET MVC.
Now, its time to have a look at How to Create a Custom Filter in ASP.NET MVC, in which you can specify your own authentications or handling etc. In our ASP.NET applications, we have use custom built filters a lot for different purposes. So, let's have a look at How to Create a Custom Filter in ASP.NET MVC:
Create a Custom Filter in ASP.NET MVC
In ASP.NET MVC, custom filters are handled by a base class named as ActionFil ...
Hi friends, I hope you are well and doing good in your fields. Today we can discuss the main topic of displacement which plays a fundamental role in the motion of the object. In simple words to study and understand the motion of objects, the concept of displacement is fundamental. When the object can moved it can change its position and cover some distance and displacement. Both quantities represented the quantitative information or description of the motion of an object. Sometimes both quantities of distance and displacement are understood the same but they are not similar to each other because in distance we can describe the motion of an object as the object can be moved from one position to another position but in displacement we can measure the distance with time.To understand the disp ...
Hello everyone, I hope you all are doing great. Today's tutorial is about the benefits of a good web host and this tutorial is especially for those engineering students who want to earn online from their website or blog. Web hosting is a service that makes it possible for individuals and organizations to post web content onto the Internet. However, the question still remains, are all web hosting exactly the same, and if not, what are the advantages of using a good host?
Although bad web hosting does exist, there are multiple ways in which your brand, business or website can flourish with the help of a good web service.
Good Uptime and Performance Speed Will Gain More Credibility
It might already be obvious but your profits will increase when your ...
Hyperconverged infrastructure becomes the go-to option for enterprise-level companies and startups looking to scale fast. While server virtualization is a mature technology, HCI continues to be one of the hottest trends in the IT industry right now. HCI offers businesses improved reliability, reduced deployment time, lower maintenance costs, and easy scalability. If you are thinking about purchasing a hyperconverged infrastructure solution, take a look at what your competition is doing. If other companies in your market are adopting HCI, maybe it's time you should, too. Let's take a look at the current state of the industry and the global HCI market growth.
The State of the Industry
HCI is a great way to reduce operating costs and simplify IT by ...
Knee milling machines are fundamental to many engineering and fab shop floors. To appreciate their usefulness, first define them by their unique Z-axis architecture. Unlike a bed mill where the head travels over a fixed bed, a knee mill is a vertical mill where the workpiece table is attached to a large cast iron knee.
The knee moves up and down along a column, exposing the X-axis (left/right), Y-axis (forward/back) from the horizontal table on top of the knee, and the spindle with the cutting tool hanging down from above. The spindle is held in a quill that can move up and down independent of the knee mill’s Z-axis. The knee is the primary vertical adjustment, but the quill carries out the detailed vertical motion of the cutting tooling. This mechanical layout gives knee milling machines ...
