Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...

If you want to monitor the utility usage in real-time and if you want to optimize the business utilities, you should make use of the energy monitoring system. It is the software that monitors the utility consumption online like the energy, fluids, gas, and so on. This system helps to calculate the consumption per area like the departments and production lines. It also helps in calculating the consumption per the production like the orders and the items that further helps in calculating the real production cost. With the help of the best type of energy monitoring tool, you can forecast the energy usage in several sectors and then create the alarm if it finds that the site has reached the contractual capacity.
The energy management system will furth ...
Hello friends, I hope you all are fine. Today, we will discuss What is an Embedded System? We will also have a look at Embedded Systems definition, examples, applications, types & development. For most of you, this term would have been quite familiar & normally people confuse it with a computer or Industrial PC etc. A computer is an application of high-performance Embedded computing but it's not an embedded system itself.
In my article, I am going to tell you all the basic information, need to know about Embedded Systems. What is an embedded system? How is it different from our personal computers? What are its main features? How can we enhance the performance of Embedded Systems? What are the main components of Embedded Systems? What would ...
Hello friends. In this lecture, we are going to have a look at the different kinds of MATLAB data types.
As we have already seen in previous lectures, MATLAB stands for MATrix LABoratory and allows us to store numbers in the form of matrices.
Elements of a matrix are entered row-wise, and consecutive row elements can be separated by a space or a comma, while the rows themselves are separated by semicolons. The entire matrix is supposed to be inside square brackets.
Note: round brackets are used for input of an argument to a function.
A = [1,2,3; 4,5,6; 7,8,9];
An individual element of a matrix can also be called using ‘indexing’ or ‘subscripting’. For example, A(1,2) refers to the element in the first row and second column.
A larger matrix can al ...
Marketing is the cornerstone of any business. Yet, so many business owners struggle to find new and innovative ways to promote their business to potential consumers. In an ever-evolving economy, marketing your endeavor is going to involve plenty of thinking outside the box. We no longer live in a world were a simple ad-campaign or coupon promotion is enough to drive eyeballs to a site or feet through the door. If you’ve been looking for new ways to market your business without breaking the bank, there is one new method you should try: text to speech technology. Not only is it one of the freshest ways to market your business, but it is one of the most affordable. Let’s take a look at how text to speech technology can be used to market your business. ...
Hi Guys! Hope you are getting along with life pretty well. I feel pleasure to guide you with valuable information related to engineering and technology that helps you make a final decision before selecting the relevant component or service for your next project. Today, I'll unlock the detailed Introduction to PCBWay - PCB Solution at Your Doorstep.
The introduction to PCB has revolutionized the electrical field drastically where different components are to be placed on a single board with flawless wiring connection without compromising the quality of the board.
PCBWay - PCB Solution at Your Doorstep
It is good practice to shape your project using breadboards when you are in the initial stages of your project and testing different methods to mee ...
Hi Friends! I hope you are doing fine. Today, I am going to give you a detailed Introduction to Arduino Nano. We will also discuss Arduino Nano Pinout, datasheet, drivers & applications. It is a Microcontroller board developed by arduino.cc and based on Atmega328p / Atmega168.
Arduino boards are widely used in robotics, embedded systems, automation, Internet of Things(IoT) and electronics projects. These boards were initially introduced for students and non-technical users but nowadays Arduino boards are widely used in industrial projects.
Any kind of technical support and help is readily provided by the Arduino community. I have also designed this video tutorial on Arduino Nano:
Here's the figure showing the key points of Arduino Nano:

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Web Server with ESP8266 using SPIFFS.
We've already seen how to create a web server and how to provide an HTML page on our ESP8266. We use the PROGMEM command to store an HTML code in FLASH memory. For a simple page, this works fine, but what if we have a more complex webpage? With a better style? What if we want to include images?
Today we will learn how to use SPIFFS with ESP8266 to store files (regardless of type) in FLASH memory.
What is SPIFFS?
SPIFFS (SPI Flash File System) is a system designed for managing SPI flash memory in embedded devices. Its main goal is to use minimal RAM to access files. It's very useful when using pen drives ...
Signal and systems is an essential subject in electrical engineering and it is not just limited to this particular branch of engineering but students of many other branches such as computer engineering learn and practice this subject in their field. For design and analysis, all engineering topics make use of models of real-world things. Signals and systems provide you with the ability to take on the challenge of getting the job done.
Signal and system are two terms that, when studied and performed together, form a fantastic visualization of different phenomena. Have a look at these two terms.
What is the signal?
A signal is defined as the description of comparing two parameters and how they vary with each other. Signals are the representation of some sort of information with the help of ...
