Hello readers, I hope you all are doing great. Welcome to Section 5 of the ESP32 Programming Series. In this section, we are going to interface different Embedded Sensors with the ESP32 Microcontroller Board. ESP32 development board is featured with some inbuilt sensors(i.e. hall effect sensor, capacitive touch sensor) so, in the initial tutorials of this section, we will explore these built-in ESP32 sensors and in the later lectures, we will interface third-party sensors with the ESP32.
In today's lecture, we will discuss the working/operation of the ESP32 built-in Hall Effect Sensor. Hall Effect sensor is used to detect the variation in the magnetic field of its surroundings. So, let's first understand What's Hall Effect:
What is the Hall Effect?
The Hall Effect phenomenon was fir ...
Hello friends, I hope you are doing very well! In today's tutorial, we will set up a simulation environment for Ladder Logic Programming. It's our second tutorial in Ladder Logic Programming Series. In our previous tutorial, we have seen a detailed Introduction to Ladder Logic Programming and we have seen that this programming language is used for PLC controllers.
As PLC is an Industrial Controller, it comes with built-in relays/transistors(with protection circuitry) and thus is quite expensive as compared to microcontrollers/microprocessors i.e. Arduino, Raspberry Pi etc. Moreover, if you are working on a real PLC, you need to do some wiring in order to operate it. So, in order to avoid these PLC issues at the beginning, instead of buying a PLC o ...
The evolution of technology over the decades has helped almost all sectors to grow and flourish. And, the medical sector is no different. The way medicine was practiced a couple of decades ago has been completely changed today. This has obviously brought in multiple benefits to the patients. The treatment time has lowered and so has the accuracy increased. People now trust technology to get their treatments done.
This article highlights certain technologies that have transformed modern medicine.
Electronic health records
This is the prime example of how technology has transformed the way of conducting treatments and keeping records. The paper filing system of patients is now long gone. It is now replaced with electronic record-keeping. This ...
Hello readers, I hope you all are doing great. Welcome to the 3rd Lecture of Section 2 in the ESP32 Programming Series. In this tutorial, we are going to discuss another important feature of ESP32 i.e. PWM(Pulse Width Modulation).
Pulse Width Modulation is a technique to reduce the voltage by pulsating it. In today's lecture, we will first understand the basic concept of PWM, and after that will design two projects to fully grasp it. In the first project, we will control the brightness of an LED, while in the second one, we will control the speed of a DC Motor.
Here's the video demonstration of PWM Control in ESP32:
Before going forward, let's first have a look at the PWM working:
What is Pulse Width Modulation?
PWM is used to control the power delivered to the load by pul ...
In our previous article, we grasp knowledge about real-life examples of the Internet of things. Now in this article, we try to elaborate on real-life applications of the Internet of things. Now a question may arise in your mind what’s the difference between the application of the Internet of things and examples of the Internet of things. I would be happy if you may elaborate on your question in addition. Simply associate degree example shows how applications are also created. Like there are several functionalities on the market in terms of arthropod genus and strategies however with examples it might be additional clear. Even so these functionalities are also wont to produce one thing awe-inspiring. In short, examples of the Internet of things is a task that is performed to develop a skil ...
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:
ESP32 Wireless Features ...
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 ...
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 nearshoring phenomenon is a global economic trend that has been going on for decades. The phenomenon is defined as moving a company’s operations to a country that is in close proximity to the company’s home base.
Nearshoring offers many benefits in terms of cost savings, but it also has many drawbacks. It can have a negative effect on wages for local workers, and it can also have an impact on the environment if the process involves bringing in outsourced goods from overseas.
To conclude, nearshoring often benefits both companies and consumers who are looking for affordable goods at low prices. However, it can have a negative effect on wages and local jobs in the long run.
It's a great way for companies with smaller budgets to have more resour ...
Manufactured parts need a quality surface finish and visual appeal before releasing them to the client or market. Although there are different methods of applying the surface finish, anodizing aluminum colors produce the best results.
There is a wide range of aluminum anodizing colors to choose from; therefore, product developers need to know how to color match before releasing the end product. Let’s examine more on anodizing aluminum parts, how to color anodized aluminum and the common anodized aluminum colors.
What is Aluminum Anodizing?
Anodizing is an electrolytic process that produces excellent mechanical properties to enhance aluminum parts' durability and visual appeal. Manufacturers use the anodiz ...
