Hello readers, I hope you all are doing great.
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT.
Project Overview
In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32.
Fig. 1
To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD).
We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to displa ...
Hello friends,I hope you all are doing great and having fun with your lives. In today's tutorial, we are gonna have a look at Model Binding in ASP.NET MVC. It's our 13th tutorial in ASP.NET MVC series. Today, we are gonna discuss a new concept in ASP.NET MVC and it's more of a luxury as it automates the job and makes our work easy.
Suppose, in your application, you want to create a registration form and thus you need to pass this data from View to your model, so that it could be saved in your database. So, in order to bind this HTTP request data from View to Model, we use Model Binding. Let's have a look at Model Binding in ASP.NET MVC in detail:
Model Binding in ASP.NET MVC
Model Binding in ASP.NET MVC is used to bind the data sent by the HTTP ...
Hello everyone, I hope you all are doing great. Today, we are gonna have a look at IF Loops in C# and it's 8th tutorial in C# series. So far, we have discussed some basic concepts in C# and now we are ready to get our hands on Loops in C#.
C#, as any other programming language, supports a lot of loop structures, we will discuss each one of them separately in our coming tutorials. Today, we will discuss the simplest of them all, which is IF loop, so let's get started with How to use IF Loop in C#:
How to use IF Loop in C#
IF Loop in C# takes a Boolean expression as a condition and if this condition is TRUE, the compiler executes the code inside IF loop { } and if the condition is wrong, the compiler simply ignores the code.
Here's the syntax o ...
Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server.
In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service.
IFTTT is used as a third-party web service to integrate Google sheets with ESP32.
Fig. 1
Creating an IFTTT Account for Integrating ESP32 with Google Sheets
We are going to create an applet (on the IFTTT server) that is responsible to integrate the Webhooks and Google Sheets services.
While operating with the IFTTT server there are some services/utilities that we are going to deal with like Applets an ...
Hi Mentees! Welcome to another electronic tutorial about the 555 Timers. We are working on Proteus and in the present experiment, we'll design the circuit of Pure Sine Wave Inverter. Inverters are the opposite devices to rectifiers. We'll show you the meaning of this sentence in action Yet, before experimentation, we have to learn some predominant concepts about the experiment. So, We'll go through the following topics:
Introduction to Pure Sine Wave Inverter.
Components used in the circuit of Pure Sine Wave Inverter.
Working of the circuit of sine wave inverter.
Circuit simulation of pure sine wave inverter in Proteus.
Introduction to Pure Sine Wave Inverter
In electronics, we examine the output of devices in the form of waves. Basicall ...
Hi readers! Hopefully, you are having a great day and exploring to learn something new. Heat is the silent killer in power electronics, and thermal vias are the unsung heroes that keep your circuit cool under pressure.
As electronic devices are miniaturized and powered with higher power, the amount of heat generated by high-speed and high-power devices has increased significantly. Proper thermal management is now one of the greatest challenges of modern-day PCB (Printed Circuit Board) design. Whether it is power supplies and LED light systems, or processors and RF modules, all electronic circuits are heat-generating. Unless treated carefully, such heat can cause degradation of components, reduced performance, signal instability, and even irreparable system damage.
To prevent such issues, ...
Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss What is Electromagnet. In 1820 physicist of Denmark Christian Orsted first time in the world found that the current produces the magnetic field. After four years of the Christian's theory in 1824 another physicist William Sturgeon who was United Kingdom native work on the findings of the Christian and created the electromagnet. It was created by the piece of iron whose design was like horse-show when the almost eighteen turns of the copper windings were rapped on the iron. The piece of iron was separated from the copper windings by insulation element.
After making these arrangements William Sturgeon connect the battery with the terminals of the copper windings, th ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to show you How to add new Library in Proteus 8 software. As we all know that Proteus doesn't have all the components in its database so if you want to add a new component in Proteus and want to use it in your simulation, then you have to add or install the Proteus library first.
On our blog, we have posted many Proteus Libraries for Engineering Students, I have given Proteus library zip file download link in each post and I hope you guys have enjoyed those libraries. But I was constantly getting this complaint from students that they are unable to add Proteus Library, especially in Proteus 8 software. So, that's why I thought of writing this tutorial, although it sa ...
Hi readers! I hope you are well and finding some thrilling advancement. In the high-speed electronic world where accuracy cannot be compromised and error is unthinkable, the Flying Probe Test is the unsung hero of PCB integrity. Today, the topic of our discourse is the Flying Probe Test and its use in PCB Fabrication.
In the complex realm of contemporary electronics, the dependability of a printed circuit board (PCB) can either make or destroy a product. With devices shrinking in size, speeding up in performance, and becoming increasingly feature-dense, the need for unflinching quality and accuracy in PCB manufacturing has grown stronger. Getting each trace, via, and connection perfectly manufactured is no longer a choice; it's a necessity. That's where Flying Probe Testing (FPT) comes in ...
