Hello readers, I hope you all are doing well. Welcome to the Section 2 (ESP32 Features) of the ESP32 Programming Series. ESP32 is equipped with numerous built-in features and in each chapter of this Section 2, we will explore one of these ESP32 features in detail.
In the previous Section(Section 1: ESP32 IDEs), we installed different software IDEs to program ESP32 boards. Among these IDEs, we are going to use Arduino IDE for programming ESP32. So, I hope all of your tools are configured properly and you are ready to explore the built-in features of ESP32.Today's the 1st Chapter of Section 2, and here we will discuss How to communicate with ESP32 Bluetooth Classic from a smartphone using Arduino IDE.
Here's the video tutorial for ESP32 Bluetooth Classic:

The most in-style web of Things (IoT) devices vary from wearable technical schools to exotic home appliances. Our advanced algorithms monitor and shield over one billion devices, which needs us to exactly establish the categories, models, and configurations of active devices. These device intelligence algorithms are the rationale behind the us having a number of the foremost precise information regarding the important quality of IoT products. The percentages provided here represent the recognition of IoT products among all connected devices, together with good phones and computers, to administer readers a clearer read of the important scale IoT devices have within the online shopper scheme. the 2 dominant device classes – computers and good phones – together compose around sixty-two of al ...
The SPI (Serial Peripheral Interface) protocol, or rather the SPI interface, was originally devised by Motorola (now Freescale) to support their microprocessors and microcontrollers. Unlike the I2C standard designed by Philips, the SPI interface has never been standardized; nevertheless, it has become a de-facto standard. National Semiconductor has developed a variant of the SPI under the name Microwire bus. The lack of official rules has led to the addition of many features and options that must be appropriately selected and set in order to allow proper communication between the various interconnected devices. The SPI interface describes a single Master single Slave communication and is of the synchronous and full-duplex type. The clock is transmitted with a dedicated line (not necessari ...
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! We hope you are very well! Today we are here for complementing our knowledge with one of the most important topics in PLC programming and practice its implementation in PLC ladder logic programming. Our topic today is about counters which help us to know the production size at any time, the repetition of specific tasks and events. Many real-life situation problems need counter like garage capacity should be tracked by using counters to report how many cars are inside and if there is room for incoming cars or it's full. Another critical problem is to count the repetitive tasks and events in manufacturing. Furthermore, counting products and pieces for taking an action like performing maintenance, stop operation, turn over to next prod ...
Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming
Fig. 1 ESP32 OTA
OTA programming is the mean by which a product manufacturer or product service provider can update the features or functionality of the device wirelessly or over the air, after the device has been deployed in the field where connecting a cable or uploading the code serially is difficult.
One key advantage of OTA is that a single central node can send an update to multiple ESPs on the same network.
The device must have a provisioning client capable of receivin ...
Hello friends, I hope you all are doing great. Today, I am going to share the 10th chapter in the PCB learning series. So far, we have studied the basics of PCB i.e. What is PCB? Main Types of PCB, techniques to mount components on PCB etc. Now, we are ready to have a look at the complete PCB Fabrication Process.
So, in today's tutorial, I am going to share a detailed guide on PCB Fabrication Process. We will discuss everything related to it i.e. How PCB boards are manufactured? Which material is used to fabricate printed circuit boards? etc. But before starting the Fabrication PRocess, we first have to understand a few terms/features. So, let's get started:
PCB of DVD player:
RoHS-compliant P ...
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 ...
Hi Geeks, welcome to our new project. Our new project is one of the most common issues you’ve seen in your cities. In this project, we are going to make a car parking system with automatic billing. In the entire world, there are an estimated 1.4 billion cars on the road, which is absolutely great news if we are considering the development of the Automobile industry. But the most serious issue is that the number of cars exceeds the number of available parking places, resulting in traffic congestion. Damaged cars due to this lack of space, fewer parking locations, lack of parking signage, informal parking, and overcharging for parking are just a few of the issues.
People are still choosing manual parking methods, which have a number of drawbacks, suc ...
Hello everyone, I hope you all are doing great. Today, we are going to share the 9th chapter in the PCB learning series, where we will have a look at the difference between Through-hole and Surface-mount technology.In our previous lectures, we studied both THT and SMT methods separately and have seen that both are used for components mounting on the PCB board. So, today, we will have a look at the difference between the two techniques. So, let's get started without wasting any time.
Through-Hole vs Surface-Mount
Let us know have a look at these differences and get to know the way forward when it comes to the process of component selection whether SMT or DIP.
Definition - THT vs SMT
THT stands for through-hole technology.
In Through-hole technology, components are mounted by ...
