Hello readers, I hope you all are having fun in your lives. Welcome to the 2nd Chapter of Section-2 in the ESP32 Programming Series. In today's lesson, we'll go over another built-in feature of the esp32 module that helps it stand out from the competition: BLE or Bluetooth Low Energy. In the previous tutorial, we discussed the Classic Bluetooth in ESP32, which is considered the predecessor of Bluetooth Low Energy(which we are going to discuss today). We will first look at, what is BLE? and why is it used?, and then will design some examples to utilize the ESP32 BLE in Arduino IDE.
What is BLE?
There have been numerous adjustments and upgrades to Bluetooth's characteristics since its inception, where Bluetooth 4.0(also called BLE or Bluetooth Smart) is the most influential.
B ...
Hello readers, I hope you all are doing great. Today, we are going to start the second section of the ESP32 tutorial series and today's our first tutorial, where we will have a look at How to Create a Web Server with ESP32. In our previous tutorial, we introduced you to the basics of the ESP32 microcontroller. where we discuss How to set up Arduino IDE to program ESP32. In this tutorial, we will discuss creating a web server using the ESP32 module.One of the most interesting features of the ESP microcontroller series is its wireless connectivity via WiFi & Bluetooth. Wireless connectivity protocols supported by ESP32 are:
Wi-fi: 802.11b/g/n/e/i
Bluetooth : BLE(Bluetooth low energy) and V4.2
What is a Web server?
A web server is software or hardware that stores, processe ...
Hello friends, I hope you all are doing great. In today's tutorial, we will discuss what is Selective Laser Sintering, why is it used for.
Selective Laser Sintering is a popular 3D printing technology used to create durable prototypes and end-use parts from CAD files. Its one of the oldest and most popular forms of additive manufacturing techniques and thanks to further technological advances, its use is becoming widespread. In this guide, we will explore what SLS is and what it is used for.
How does Selective Laser Sintering work?
SLS uses a nylon or polyamide powder which is spread successively in thin layers with a high-powered laser that selectively sinters the powder according to data derived from digital models. This process is repeated la ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to design a Proteus Simulation for Automatic Plant Watering System using Arduino. We have designed this project for engineering students as it's a common semester project, especially in electrical, electronics and mechatronics engineering.
The two most significant hazards to the agriculture industry are the need for extensive labor and a scarcity of water. According to the World Wildlife Fund (WWF) organization, water shortages might affect two-thirds of the world's population by 2025, putting both the ecosystem and human health at risk. The use of automatic plant watering systems eliminates both of these problems by watering plants at specified times and amounts whil ...
Are you here to learn about Databases and CRUD operations in the C# programming language? If so, then you will be an expert in no time. Learning Databases and CRUD operations in C# is not a piece of cake. But, if you know all the terms and steps of CRUD operations and databases in C#, it will not be rocket science for you. This article contains all the information you should know regarding databases and CRUD operations. So, keep reading till the end!
C# Programming Language: An Overview
We know that you are already aware of the C# programming language. So, here is a quick overview of the C# programming language before we move to the actual topic:
C#, also known as C-Sharp, is an object-intended coding language that operates on the .NET Platform ...
Hello everyone, I hope you're all doing well. In the previous lecture(Chapter 0: ESP32 Pinout), we discussed the ESP32 features & specs in detail. Today, we are officially starting this ESP32 Programming Series. In this ESP32 Programming Series, we will start with basic concepts and
will gradually move towards complex topics. I will try to keep this
ESP32 series as simple as I can. But still, if you encounter any issues,
please ask in the comments, will try to resolve the issues as soon as
possible.As ESP32 has numerous features & applications, so I have divided this series into different sections. I have named the 1st section "ESP32 IDEs". In this section, we will discuss different IDEs used to program ESP32 boards. In each Chapter of this section, we will install one of t ...
Hello friends, I hope you all are doing great. In today's lecture, we will have a look at the I2C Communication with STM32 Microcontroller board. I am going to use the Nucleo board for today's lecture. In the previous lecture, we have discussed STM32 Serial communication both in Interrupt Mode and polling Mode. Today, we will study another way of communication(i.e. I2C) with STM32. So, let's first have a look at what is I2C Communication:
What is I2C Communication?
I²C (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits. Like any serial protocol, one of its advantages is that of using only two lines that transmit or receive a sequence of bits, the limit is the communication speed which has been improved over the years.
The bus was conceive ...
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 ...
USART is the acronym for Universal Synchronous-Asynchronous Receiver-Transmitter, and is the advancement of the old UART that was unable to handle synchronous communications; in computers, it deals with the management of communication via the RS-232 interface.
Generally, in the communication between devices, there is a transmitter and receiver that can exchange data bidirectionally, thus it happens for example in the communication between the microcontroller and third-party peripherals.
What is Serial Communication?
In serial communications, the transmitting device sends information (bitstream) through a single channel one bit at a time. Serial communications are distinguished from parallel communications where the bitstream is sent over several d ...
Hello friends, I hope you all are fine. Today, we are starting a new tutorials series on Ladder Logic Programming, used in PLC. It's our first tutorial in this series, so we are going to have a look at the detailed introduction to PLC and ladder logic. After welcoming every one of engineers, technicians, students, and hobbyists who have come to read this article willing to learn PLC programming, I would like to introduce one of the most used programming languages of PLC. The language we introduce here is a visualized language that connects and combines graphical symbols in logical flow same as the way we wire electrical circuits and that is the secret behind its simplicity not only in implementation but also in diagnosing problems.
Ladder Logic Pro ...
