Hello readers, I hope you all are doing great. In this tutorial, we will learn how to update a webpage using Server-Sent Events and the ESP32 web server.
What is Server-Sent Events (SSE)?
It is a server push technology that enables the client devices to receive automatic updates from a server over HTTP (Hypertext Transfer Protocol) connection. SSE also describes how the server can initiate data transmission towards the client once an initial connection with the client has been established.
We have already posted a tutorial on how to implement Web socket protocol with ESP32 which is also a protocol used to notify events to a web client. Both the Server-Sent Events (SSE) and Web-Socket technologies seem to be quite similar but they are not.
The major difference between the two is that SSE ...
In several domestic, commercial, or industrial settings where gases or liquids have to be distributed or mixed, solenoid valves are used to ensure the accuracy and precision of all the control aspects. To help you understand the types and working principles of solenoid valves, selection criteria, and everything in between, we’ve covered all you need to know about these electrically controlled valves. You should also have a look at the Linear Solenoid.
What are Solenoid Valves and How Do They Work?
Solenoid valves are electromechanical devices that feature two major components: a valve body (G) and a solenoid (Figure 1). The solenoid is an electric coil (A) with a movable magnetic core that’s centrally located, also called a plunger (E). It’s also made up of an armature (B), a shading rin ...
Hello everyone! I hope you all will be absolutely fine and having fun. In the tutorial Declaration of variables in MATLAB, I will elaborate you that how to declare different variables in MATLAB and how to manipulate those variables without assigning them with the values. Before going into the details of this tutorial you must go through Introduction to MATLAB, because understanding MATLAB first is better. This will help you in better understanding of this tutorial.
Variable declaration is one of the most important and compulsory steps while writing the code to perform any task. Without the declaration of the variables we can not proceed further to perform our task properly. So, if we want to do the different tasks in a proper way we must need to ...
Sound off, scroll on.
Yes, now, silence is the new norm for videos. You have seen many people watching reels in silent mode while traveling, in a meeting, or sitting in a crowded place. According to research, around 80% of social media users watch video content without sound.
This shift from full-sounding videos to silent clips redefined how videos perform online. So, now, subtitles or automatic captions are not optional, but they are essential to keep viewers engaged and improve SEO. This not only helps viewers understand your content but also keeps them watching longer. Higher watch time means better engagement and improved retention.
Are you looking for an easy-to-use auto captions generator that takes less time? If yes, then Wondershare’s Filmora can be your great option. This AI-po ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new Gas Sensor Library for Proteus. I hope you guys are going to enjoy this one. We are all well aware of Gas Sensors which are used for the detection of different gasses in the atmosphere. These sensors are not available in Proteus so that's why I have designed a library using which now you can use these different gas sensors quite easily in Proteus software. You can interface this Gas Sensor with any Microcontroller i.e. Arduino, PIC Microcontroller or 8051 Microcontroller etc.
In this Gas Sensor Library for Proteus, I have added eight different Gas Sensors, which are used for the detection of different gases. As we all know that Proteus is a simula ...
Hello everyone, hope you all are fine and having fun with your lives. Today, I am going to share 8051 Microcontroller Projects. Recently, I have shared quite a lot of tutorials on 8051 Microcontroller which are not much arranged as a whole. So, today, I thought to arrange all those tutorials and place them here so that you can get all of them quite easily. I will upload more 8051 Microcontroller Projects and I am gonna add their links in this post so stay subscribed to this post if you are interested in learning 8051 Microcontroller.
8051 Microcontroller, as we all know, is another Microcontroller series just like PIC Microcontroller or Arduino etc. The benefit of 8051 Microcontrollers is that they are quite cheap and easily available so if you ar ...
Hello Everyone! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to CD4035.The CD4035 is a shift register that is mainly used in counters, control circuits, and registers. It contains clocked signal serial chip that is a four-stage register. Synchronous Parallel inputs are provided to each stage and serial inputs are offered to the first stage via JK logic.
I suggest you read this post all the way through as I’ll detail the complete introduction to CD4035 covering datasheet, pinout, features, alternatives, and applications. Let’s jump right in.
Introduction to CD4035
The CD4035 is a shift register that is a 16-pin device and is mainly used in control circuits, counters, and registers.
It is a four-stage register that ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at different Razor Layout Views in ASP.NET Core. It's our 10th tutorial in ASP.NET Core series. You must have noticed in websites that they have common sections, which remains the same throughout the website i.e. Header Section, Footer Section, Sidebar etc.
In today's lecture, we will have a look at how to design these default layouts of a website. We have already discussed the MVC architecture in detail so now it's time to start building our site's layout or basic structure. Today we will just discuss different files available in ASP.NET Core for default layout designing. So, let's get started with Layout View in ASP.NET Core:
Razor Layout View in ASP.NET Core ...
Good day peeps! Welcome to another episode of the MQ gas sensor series and today, the topic is the MQ214 natural gas sensor. We know that natural gas is inflammable and is utilised widely for cooking and other purpose in domestic areas as well as a fuel in multiple industries. The leakage of natural gas can be the reason for the accidents and its accumulation may even result in the explosion. Moreover, continuous inhalation of this gas can cause health issues such as nausea, dizziness, and headaches therefore, instant detection of its leakage is crucial. For this, one of the best options is MQ214 because it has a fast response time, low power consumption and is easily available.
In this article, we are discussing the fundamental points about this sensor. We’ll see its basic introduction ...
Hello everyone! I hope you will be fine and having fun. Today, I am going to give a detailed Introduction to Relay. In this tutorial, we will learn the basics of relays, the working principle of relays, the types of relays and their applications in detail. A relay is a simple automatic switch that opens and closes the circuit(either electronically or mechanically) based on its input signal. A relay is an electromechanical switch that uses electromagnetism from a small current or voltage to switch higher current or voltage for different appliances. When a relay is in a Normally Open (NO) state, no current passes through it and when the relay is energized, the current starts to flow and we can say the relay is in a Normally Closed state. You should also have a look at Relay Interfacing with ...
