Hello readers, I hope you all are doing great. In this tutorial, we will learn how to update a webpage using Server-Sent Events and the ESP32 web server. What is Server-Sent Events (SSE)? It is a server push technology that enables the client devices to receive automatic updates from a server over HTTP (Hypertext Transfer Protocol) connection. SSE also describes how the server can initiate data transmission towards the client once an initial connection with the client has been established. We have already posted a tutorial on how to implement Web socket protocol with ESP32 which is also a protocol used to notify events to a web client. Both the Server-Sent Events (SSE) and Web-Socket technologies seem to be quite similar but they are not. The major difference between the two is that SSE is ...
Product designers nowadays have access to various technologies for creating multiple prototypes. These include traditional methods such as pen-and-paper sketching and cutting foam blocks, as well as more modern technologies such as 3D printing and CNC machining service. However, today we will focus on the additive manufacturing technique and what you should look for during your search. Numerous businesses embrace the technology by delegating tasks to professional 3D printing services . In the globally competitive environment, adding a supply partner to the company's value chain is the way to go because the technology is capital-intensive to implement. To help more businesses adopt the technology, we've created a simple guide to help them select the best 3D printing solutions partners. Avai ...
3D printing is one of the most promising technologies in recent breakthroughs. One of the most inherent benefits of 3D printing is additive innovation; it opens up an entirely new way of creating products and provides numerous benefits over traditional fabrication techniques. Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online ) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project? Affordability One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of money spent on building a structure. Whene ...

So far, the 2020s are turning out to be an era when engineering advances have come to the rescue of everyda ...
Welcome to chapter 8 of our python tutorial. In the previous chapter, we learned about Python numbers and how to use them in expressions. Throughout this chapter, you'll look at frequent examples of incorrect Python syntax and learn how to fix them. At the end of this tutorial, you will: Distinguish incorrect syntax in Python Get familiar with SyntaxError tracebacks Fix improper syntax or avoid it altogether In Python, what is an invalid syntax? Before transforming your Python code to Python byte code, the interpreter parses it. The parsing stage is where the interpreter searches for any instances of improper syntax in the program. Using the wrong syntax in your Python code will lead the interpreter to be unable to decipher it. The interpreter will try to show you exactly where the issue o ...
ESP32 module comes with multiple inbuilt features and peripheral interfacing capability is one of those features. ESP32 module also consists of an inbuilt temperature sensor, but that can only measure the temperature of the ESP32 core not the temperature of the surrounding environment. So it is required to use a peripheral sensor to measure the temperature of the surrounding environment like home, garden, office etc. Hello readers. I hope you all are doing great. In this tutorial, we will learn how to interface DHT11 (temperature and humidity sensor) with the ESP32. Later in this tutorial, we will discuss how to share the sensor readings obtained from the DHT11 sensor to a web server. Before moving towards the interfacing and programming part, let’s have a short introduction to the DHT11 s ...
Public cloud computing systems enable businesses to complement their data centers with worldwide servers that can scale processing capabilities up and down as required. In terms of value and security, hybrid public-private clouds are unparalleled. However, real-time AI applications demand substantial local processing capacity, frequently in areas distant from centralized cloud servers. speedpak tracking is among the services including AI for the safety of your goods and parcels. Moreover, some workloads demand low latency or data residency and must stay on-premises or specified locations. That is why many businesses use edge computing to implement AI applications. Instead of storing data in a centralized cloud, edge computing saves data locally in an edge device. Moreover, the gadget may f ...
The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet. To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers. Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications. Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR se ...
Welcome to the fourth lesson of this python course. Our previous session taught us how to utilize the print function in python , so we have a firm grasp of the terminology and the functions themselves. In this lesson, we'll cover a few more Python terms, such as: Strings Operators Input function Also, we'll build a simple program to print out an imagined dog so that we may better grasp how these concepts are employed. So, let's get started now. Why do we need to understand these terms? Programming is a lot like building a structure out of blocks. Even with just a few types of children's toy blocks and some time and imagination, you can build anything. Because we'll be utilizing these phrases all the time in programming, it's critical that you know what they mean and how to use them. What e ...
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, TVs, etc. There ...
