Hello readers, today we will learn about the messaging protocol supported by ESP32(called MQTT protocol), which is used for IoT applications. The communication protocol to be used for data transmission and connectivity in web-enabled devices depends upon the type of IoT application.
The Internet of Things (IoT) is a network of interconnected computing devices like digital machines, automobiles with inbuilt sensors, having unique identifiers and the ability to communicate data over a network without the need for human intervention.
Before implementation, let's first have a look at what is MQTT Protocol?
What is MQTT?
MQTT stands for Message Queuing Telemetry Protocol and is a messaging or communication protocol used for IoT applications.

Companies usually outsource electrical engineering when internal capacity and project demand no longer align. A firm can be staffed well enough and still come under pressure once a few permit sets, coordination rounds, and late design revisions land at the same time. In that situation, outside support is less a strategic slogan and more a delivery decision.
Sometimes that help comes from a freelance electrical engineer brought in for a defined package. Sometimes it comes from a larger external team that can handle production work at scale. The appeal is fairly straightforward. A project keeps moving, the internal team has room to think, and the firm does not have to solve a short-term workload spike with a long-term hiring commitment.

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through Cloud Computing Services.
The requirement to process and store data varies from business to business. Some organizations can handle data in on-site data centers. They have a team of experts who handle IT infrastructure and install, maintain and upgrade hardware based on the availability of data. This approach is expensive, no doubt. Some companies, however, don’t accept this model. They prefer cloud computing which is the availability of on-demand IT infrastructure over the internet. This model sets them free from handling and managing on-site data centers, instead, everything is managed and controlled by the cloud service providers. End users only pay for the computing services they use. ...
You don’t have to be a coder to be a DIY kind of guy. You can even use something as simple as Java or Swift to get your projects up and running. But sometimes, things don’t go as planned no matter how many times you debug. Those are the times when the Swift hits the fan and the project comes to a grinding halt. That is when you hear the voice of Luke Skywalker pushing you to stop running around in circles and just use the force. You roll up your sleeves and that is when the magic begins.
Electronic tinkering is for people of all skill levels. Here are a few projects that reflect different skill levels:
As a Youngling, you can build your own Bluetooth speaker. - simple concepts, accessible supplies, low time commitment
Once you advance to Padawan, you will be ready to build your own g ...
You can use a multimeter to figure out what's wrong with the electrical system in your car. Most of the time, if you check for voltage and continuity, you can figure out where the problem is coming from. This article will show you how to use a multimeter on a car.
First, make sure the multimeter isn't on. Then connect the positive lead to the positive terminal on the battery. Connect the negative lead to a metal piece on the frame of the car. The last step is to turn on the multimeter and read the results. If it says 0 volts, it means that no electricity is moving through the circuit. If the voltage is 12 volts or more, then there is a current in the circuit.
A multimeter can be helpful if you can't figure out what's wrong with your car's electrics. You should be able to fix many c ...
Hello friends, I hope you all are fine and enjoying good health. Today's tutorial, as the name shows, is on Introduction to PLC. PLC is an abbreviation of Programmable Logic Controller. Recently I worked on a project in which I have to design a Automated coffee Mixing Machine Using PLC. It worked quite good and I had a great time while working on it. After completing that project, it occurred to me that I haven't posted any tutorial on PLC. So I thought of starting this tutorial. This tutorial is not gonna cover in single post so my plan is to divide it in parts.
Today. I am gonna give an overview about PLC. We will have a look on basics i.e. what is PLC? Why we use PLC instead of microcontroller like Arduino or PIC Microcontroller? What's its adv ...
Hello, dear tech savvies! We hope everything is going fine with you. Today we’re back with another interesting project. Do you ever wonder how amazing it would be to have a text reader that would be able to read texts from pictures and videos? Think about a self-driving car that can read the road signs meticulously and go to the right direction. Or imagine an AI bot that can read what is written on images uploaded to social media. How nice it would be to have such a system that will be able to read vulgar posts and filter them even when they are in picture format? Or imagine a caregiver robot that can read the medicine bottle levels and give medicines to the patients always on time. Now you understand how important it is for AI solutions to recognize texts, right?Today, we are going to ...
Hi Friends! I hope you are enjoying your life and getting most out of it. We are here to give you daily dose of useful information so you can excel and grow in your relevant field and stand out from others. Today, I'm going to uncover the details on the Introduction to SG3525. It is a pulse width modulated control circuit that is used to control switching power supplies and particularly helps in providing lower external parts count and improved performance. I'll try to cover every aspect and properties related to this modulated control circuit so you get clear idea what is it about and what are its main applications. You can also have a look at Introduction to SG3524 which is mainly used in regulation power supplies and switching regulators.

3D printing is one of the most promising technologies in recent breakthroughs. One of the most inherent benefits of 3D printing is additive innovation; it opens up an entirely new way of creating products and provides numerous benefits over traditional fabrication techniques.
Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project?
Affordability
One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of ...
Welcome to the fourteenth chapter of our python tutorial course. In the last lesson, we looked at sets and operations done to sets, including union and intersection. In this tutorial, we'll take a closer look at lists and tuples to see how they're used. Python's most versatile and useful data types are lists and tuples. A non-trivial Python application will nearly always have these.
What will you learn?
Lists and tuples have a number of significant features that you'll learn about. In this course, you'll understand the definitions and applications of these terms. By the time you're done, you'll know when and how to employ different Python object kinds.
What are lists?
In other words, Lists are similar t ...
