ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on another ESP32 application in the field of IoT.
Hello readers, I hope you all are doing great. In the previous tutorial, we learned how to send sensor readings from ESP32 to the cloud (ThingSpeak webserver).
In this tutorial, we will learn to send HTTP POST requests from the ESP32 board to ThingSpeak and IFTTT APIs.
What is HTTP?
Fig. 1 Hypertext Transfer Protocol
HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text transfer protocol was invented alongside HTML (Hypertext markup language) to create the first interactive, text-based web browser: the original www or World Wid ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a simple tutorial on Image zooming with bilinear Interpolation in MATLAB. We have seen many software in which there's an option of zooming an image. For example, if you have used paint or photoshop then you have seen that you can zoom your image quite easily by clicking a button. Today's we are gonna do the same thing but in MATLAB and we will have a look at the code behind this feature.
Now, when we are zooming some image then in fact we are increasing the pixels of that image and in order to do that we have to fill those extra pixels with the color of their neighbor pixel. This thing is know as interpolation. There are many different techniques for in ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at Flow Switches And Flow Meters. There are a lot of flow meters and flow switches types on the market today. Thus, it is sometimes troublesome to choose the ideal device for your demands.
So, why is learning the different types of flow meters and flow switches, as well as their differences, essential? You might wonder why you need to know about this. Well, it is necessary to understand how flow switches differ from flow meters as this impacts your business. There is a lot to consider in choosing the right fit for you and not knowing how it works might cost you another expense.
When you are choosing flow meters and flow switches, it is essential to know ...
Welcome to the tenth lesson of our python course. In the previous tutorial, you learned about syntax errors in Python, and in this lesson, we will look at one more error notice that is given by Python when there is an error in your code. So, without further ado, let's get started.
Any time an exception is thrown in your code, Python shows you the stack trace. If you don't know what the traceback output is showing you, it can be a little overwhelming. Python's traceback, on the other hand, provides a goldmine of information that can assist you in figuring out why an exception was triggered in your code and fix it. It's essential to learn how to use Python traceback to become a better coder.

Hello Friends, I hope you all are fine and doing great in your lives. Today I am going to tell you about the essential things you need to know for learning embedded system programming. An embedded system relies heavily on its program so it is very important to know the programming basics. First, let’s define embedded systems before going into the details of embedded system programming. In my last two articles, we have seen What is Embedded Systems ? in which we have learn the basics of Embedded Systems and after that we threw some light on What is Embedded Computer ? So, if you guys haven't read them yet then I would suggest you to must read them first because they will give you the basic idea of Embedded System Programming.
An embedded system is ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to elaborate you about Introduction to L298. L-298 is an Integrated Circuit (IC) available in two type of packages now a days which will be given later. L 298 is a dual full bridge driver that has a capability to bear high voltage as well as high current. It receives basic TTL (Transistor Transistor Logic) logic levels and is able to operate the different loads such as DC motors, stepper motors, relays etc. You should also have a look at Introduction to L23D.
L-298 has two enable input to control any device by enabling or disabling it. L 298 IC is most commonly used to make motor drivers or motor controllers. These motor controllers can be controlled by any ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
With the ever-advancing technology, the number of industries turning to remote working is rapidly increasing. Jobs previously requiring workers to work from the office can now be effectively performed remotely. Remote engineering is also on the rise, with different engineers able to work from home.
Whether you are designing infrastructure, coding software, or creating new machinery, the shift towards remote work offers engineers more balance in their profession and personal lives. There are numerous opportunities for remote jobs, from software engineers to mechanical engineers and civil engineers to electrical engineers.
This article explores different types of engineers who can work remotely.
Software Engineers
Software engineering is the most delocalized class of engineering in this ...
Hi Friends! Hope you’re well. In this post today, we’ll discuss What is Raspberry Pi Zero? We’ll also cover Raspberry Pi Zero Pinout, Specs, Projects & Datasheet.
Developed by Raspberry Pi Foundation, Raspberry Pi Zero is a tiny single-board computer, initially introduced to teach basic computers in schools. Later, it rose to popularity due to its low cost and open source design. Now it is widely used in robotics and embedded systems to develop IoT projects. This device is among the bestselling British single-board computers. I suggest you read this post all the way through as I’ll cover Raspberry Pi Zero in detail. Let’s get started.
