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 ...
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 ...
Hello friends! I hope you all had a great start to the new year.
In our first lecture, we had looked at the MATLAB prompt and also learned how to enter a few basic commands that use math operations. This also allowed us to use the MATLAB prompt as an advanced calculator. Today we will look at the various MATLAB keywords, and a few more basic commands and MATLAB functions, that will help us keep the prompt window organized and help in mathematical calculations. We are also going to get familiar with MATLAB’s interface and the various windows. We will also write our first user-defined MATLAB functions.
MATLAB keywords and functions
Like any programming language, MATLAB has its own set of keywords that are the basic building blocks of MATLAB. These 20 building blocks can be called by simply ...
Are you a new architect or aspiring to become an architect? If the answer is "yes," you will need to have the best programs to make a mark in this industry. Well, the two most important categories of software in architecture are building information modeling (BIM) and computer-aided design (CAD). Which one should you use? Keep treading as we dig deeper into each category and highlight key examples for you to consider.
What is CAD?
CAD, shortening for computer-aided design, is the use of computers to help create, modify, and optimize building design. CAD programs are developed to help people design and document their models using advanced computer technology. CAD files are particularly useful where multiple parts are required to fit precisely in a ...
Hello Friends! I hope you all are doing great welcoming 2022. With the start of the New Year, we would like to bring to you a new tutorial series. This tutorial series is on a programming language, plotting software, a data processing tool, a simulation software, a very advanced calculator and much more, all wrapped into one package called MATLAB.
We would welcome all the scientists, engineers, hobbyists and students to this tutorial series. MATLAB is a great tool used by scientists and engineers for scientific computing and numerical simulations all over the world. It is also an academic software used by PhDs, Masters students and even advanced researchers.
MATLAB (or "MATrix LABoratory") is a programming language and numerical computing environm ...
Greetings and welcome to today’s lecture. Today, we are going to focus our discussion on the Surface Mount Technology of PCB components mounting. It's our 8th tutorial in the PCB learning series and is going to be a very interesting and interactive class. In Surface-mount technology, SMT components(having small pads) are
placed on the surface of the PCB board and their pads are soldered on
the same side of the board.
As we discussed in our last lecture on Though-Hole Technology, there are two main methods used to mount components on PCB boards. We studied THT in the last lecture and today, we will focus on
Surface Mount Technology (SMT), we will discuss SMT classifications, types, applications, advantages and disadvantages in detail.

The Internet of Things ( or IoT) is a network of interconnected computing devices such as digital machines, automobiles with built-in sensors, or humans with unique identifiers and the ability to communicate data over a network without human intervention.
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send sensor readings from ESP32 to the ThingSpeak cloud. Here we will use the ESP32’s internal sensor like hall-effect sensor and temperature sensor to observe the data and then will share that data cloud.
What is ThingSpeak?
Fig. 1: ESP32 ThingSpeak
It is an open data platform for IoT (Internet of Things). ThingSpeak is a web service operated by MathWorks where we can send sensor readings/data to the cloud. We ...
We all have heard of this term by now. IoT or the Internet of Things is an ingenious yet innovative technology that is the support system for uncountable apps in almost all sectors.
With the ever-increasing demand for higher technology, there has been a rapid growth in the field of IoT. You would require a professional IoT app development company for implementing the correct connected technology solution for your business.
As we are moving towards and becoming the tech generation, it's exciting to know how IoT Application Development has a huge Market Potential - wondering how it is possible? Let us tell you more.
Do You Know?
Let us tell you a fun fact. Worldwide there are about 9 billion Internet of Things (IoT) devices connected in 2020, which ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B20, DHT11, BMP280 etc. We will first discuss the basics of this Internal Temperature Sensor and then will design a code to monitor the change in temperature by changing the frequency of the ESP32 CPU.
