Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Add Basic Function in WordPress Plugin. In the previous tutorial, we have seen How to Create a Simple WordPress Plugin, and today we are gonna add some basic functions in it, which are kind of compulsory. You may not find them useful right now but they will come in handy when we will work on complex plugins.
It's the second tutorial in WordPress plugin creation series. If you got into any trouble then ask in comments and I will try my best to resolve them all. So, let's get started with these basic functions and add then in our newly created WordPress plugin:
Add Basic Functions in WordPress Plugin
As we have already created the class for our wordp ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new project which is Line Following Robotic Waiter. I hope you guys are gonna enjoy it. I have shared all the details below so that if you wanna design it then you can easily do it. I have designed this project for a client and it worked quite perfectly so I thought to share it with you guys as well.
I have designed this Line Following Robotic Waiter using Arduino UNO board. I have also shared the code below and have given all the instructions but still if you got into any problem then ask in comments and I will solve your problems. I have also shared a video below which will show you the working of Line Following robotic Waiter. So, let's get start ...
Hey Guys! I hope you all are doing great. Today, I am going to give a detailed Introduction to Data types in C#. It's our 3rd tutorial in C# series & it's a theoretical tutorial so you just need to read it once.
I'll try to cover every aspect related to Data types in C# so you get a clear picture of what are data types and why we need them? So, let's get started with Introduction to Data types in C#:
Introduction to Data types in C#
Data Types in C# are used to inform the compiler about the type, size & nature of data that can be stored in a variable.
Whenever we need to declare a variable, we need to inform the compiler about the data size & type of the variable.
There are 3 types of data types available in C# programming, ...
The Internet of Things ( or IoT) is a network of interconnected computing devices such as digital machines, automobiles with built-in sensors, or humans with unique identifiers and the ability to communicate data over a network without human intervention.
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send sensor readings from ESP32 to the ThingSpeak cloud. Here we will use the ESP32’s internal sensor like hall-effect sensor and temperature sensor to observe the data and then will share that data cloud.
What is ThingSpeak?
Fig. 1: ESP32 ThingSpeak
It is an open data platform for IoT (Internet of Things). ThingSpeak is a web service operated by MathWorks where we can send sensor readings/data to the cloud. We ...
Hello everyone, I hope you all are fine and having fun. Today's tutorial is a quick one and is about how to use C# Comments. Comment is an important part of any programming language, although its not a directly part but they indirectly help a lot especially in complex projects.
I have also shared a tutorial on How to use comments in c++, you should read that post as well because I have explained few basic concepts in it. You guys are also welcome to give us feedback about this new C# tutorial series. If you have any suggestions about it then do let us know in comments.
How to use C# Comments ???
Comments are simple documented text lines, completely ignored by the compiler and are used to explain or provide any additional information about codi ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about getting started with pixy camera. Now, the first thing comes in mind is what is Pixy Camera so let's first have a little introduction about Pixy Camera on which I recently worked. Pixy Camera is a small camera board which uses NXP microcontroller. Its a very powerful board and can get easily interfaced with simple Arduino UNO board. So, now we can do image processing even on Arduino UNO. Image Processing needs a powerful board that's why we can't interface simple webcam with Arduino UNO or mega etc. Before using pixy camera, when I need to do on board image processing I always used either Arduino YUN, Raspberry Pi or Arduino USB host shield but still it was ...
Hello learners, Welcome to another tutorial on signals and systems. We are learning about the responses of the signals. We all have experience in situations where the change in the frequency of a system, such as radios or control systems, results in a change in the working or result of that system. So we have the idea that frequencies play an important role in different types of systems. In the previous lecture, we saw the impulse response of the system. Our mission today is to learn about the frequency response of the LTI system. We will learn all the basic information about the topic and will revise some important points as well. To do this, have a look at today’s concepts:
What is the LTI system?
What is frequency response?
How is frequency response performed without the function i ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am going to share Interrupt based Digital clock with 8051 Microcontroller. In the previous post, I have explained in detail How to use Timer Interrupt in 8051 Microcontroller. We have seen in that post that we can use two timers in 8051 Microcontroller which are Timer0 and Timer1. Using these timers we can easily generate interrupts. So, before going into details of this post, you must read that timer post as I am gonna use these timer interrupts in today's post.
After reading this post, you will also get the skilled hand on timer interrupt and can understand them more easily. In today's post, I am gonna design a digital clock which will increment after every o ...
Hi Guys! We always keep on working to find useful ways that give you quick and economical solutions to your needs. Today, I am going to give a quick review about WellPCB and why you prefer them if you intend to making high quality PCBs with reasonable price.
Where there is a need of electronic devices, there is a need of PCB. Joining number of components on board using old conventional with end to wiring is becoming obsolete that happened to cover more space, carry heavy weight and turned out to be expensive with the ability to performing less number of functions. This led to the introduction to printed circuit board.

Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you an elaboration on Introduction to UA741. UA 741 is basically a general purpose operational amplifier. This amplifier is considered to be ideal for the voltage follower applications because latch-up operations are no there in its case and it moreover it has High Common Mode Input Voltage Range (HCMIVR). UA-741 is a high performance operational amplifier made up of single silicon chip.
UA 741 is stable without using external components, due to the internal frequency compensation and this device is safe from the short circuiting. In order to cancel the effect of offset voltages we can use a small valued potentiometer/resistor. UA-741 can operate in a temperat ...
