Hello friends, hope you all are fine and having fun with your lives. In today's tutorial, we are gonna see Color Detection in Images using MATLAB. In the previous tutorial, I have posted about How to Detect Circles in Images using MATLAB in which we have detected objects based on their geometrical figure means either they are circle or not but today we are gonna distinguish objects based on their color i.e. whether they are red colored or green colored etc. Its a quite simple tutorial and comes in the basic category. We will first detect the color and then will create a boundary around that object and will also show its XY coordinates as well.
Image processing is an important tool of MATLAB. We can quite easily do the image processing in it using ...
Hello guys, hope you are doing good and enjoying your lives. Today, I am going to introduce you to the blocks of a blockchain. I gave you an understanding of blockchain, its characteristics, and some idea about accounts and wallets in my previous tutorials, and today my article is about the structure of a block in the blockchain.
I will first define the block before going into the details about its structure. So let’s start without any further delay.
Block in Blockchain
A block is actually the building block or the key element of a blockchain.
The definition of a blockchain is based on its blocks. As I defined in my previous posts, a blockchain is a chain of multiple blocks.
Blocks contain transac ...
Hi Guys! hope you are doing great today! We come this time with a complete project to work out together starting from the point at which we sit with the client and receive the logical narratives that represent what they want to implement. We are going to start with a simple project this time and continue increasing the scale and complexity of the requirements through the incoming tutorials. The project we are going to implement today is one of the most common tasks that we can find in every place in our real life which is the control of the garage door. That could be found in private property or commercial buildings or public garages. Too many things need to be controlled in garage doors and several scenarios could come to your mind. However, take it as a rule of thumb that we design our p ...
Hello friends, I hope you all are doing great. In today's tutorial, I will show you how to perform Simplest Half Wave Rectification in Proteus. In this tutorial, we will design a simple Proteus simulation, where we will use a diode for half-wave rectification.
Before designing the Proteus simulation, we will first have a theoretical overview of Half Wave Rectification as it's always the best approach to read theory before practical (Proteus Simulation). So, let's get started:
What is Rectification ???
Rectification is an electrical process, used to convert Alternating(AC) Voltage into Direct(DC) Voltage using a circuit called rectifier.
The Rectification process is always carried out using diodes, as we know diodes allow the current to flow in one direction only, thus t ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Namespaces in C#. Namespaces are considered as libraries in C#. If you have worked on any other programming language then you must be aware of the term library which contains all classes & methods etc. In C#, this functionality is performed by namespaces.
In 12th tutorial, we have seen Introduction to Methods and in 13th part, we have seen Classes in C#. Methods are simple storage units and stores code only, Classes are slightly bigger storage units and can store methods. Now Namespaces are giant storage units, which can save anything in them i.e. classes, methods, namespaces etc. So, let's have a look at them in detail:
Int ...
This is the third tutorial in our Raspberry Pi programming course. In the previous chapter, we learned how to install Raspbian on our Raspberry Pi mini-computer. In this chapter, we'll learn how to use a VNC server to remotely control and see its desktop from our computer.
What is VNC?
Computing over a network is known as "virtual network computing," or "VNC." To remotely control another computer, you can use this screen-sharing technology, which works on all major operating systems. As a result, a remote user can interact with a computer's display (screen, keyboard, and mouse) as if they were sitting right in front of it.
VNC takes advantage of the client/server concept. Rather than installing a VNC s ...
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 s ...
Hello friends, hope you all are fine and having fun with your lives. In today's tutorial, I am gonna show you How to Configure NI MyRio on Wifi. In our previous tutorial, Getting Started with NI MyRio I have show you how to get started with NI MyRio and control LEDs of NI MyRio but you have seen that we have done that over USB. In simple words, we have controlled the LEDs and gyroscope of MyRio over USB but in today's tutorial, first of all, we are gonna configure NI MyRio on Wifi and then we are gonna control all those things over Wifi instead of USB.
If you have a project on MyRio then its my recommendation to use Wifi instead of USB for upload and testing your codes because Wifi is quite flexible in use and you no more restricted to use the USB ...
Hey, everyone, hope you are doing great. In today's article, we are going to explore C# Checked ListBox Control. In the previous article, we discussed in details about C# TextBox, C# Label, C# ListBox, C# ComboxBox and C# Button. C# Checked ListBox plays very important role in Point Of Sale applications. In some words, we can say this is a combination of check boxes and list. C# Checked ListBox is used to gain specific information from end-user. It's mostly used in survey-based application to gain the voting for a specific purpose.
We will work with Checked ListBox same as we have worked with ListBox & ComboBox. You can use C# Checked ListBox for multiple purposes. You can use this as the attendance taker to mark the attendance of students.
C# ...
Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B20, DHT11, BMP280 etc. We will first discuss the basics of this Internal Temperature Sensor and then will design a code to monitor the change in temperature by changing the frequency of the ESP32 CPU.
