Hello friends, hope you all are fine and having fun with your lives. Today's post is about interfacing of RFID module RC522 with Arduino. RC522 is very simple yet effective module. It is an RFID module and is used for scanning RFID cards. Its a new technology and is expanding day by day. Now-a-days it is extensively used in offices where employees are issued an RFID card and their attendance is marked when they touch their card to rfid reader. We have seen it in many movies that when someone places ones card over some machine then door opens or closes. In short, its a new emerging technology which is quite useful.
I recently get a chance to work on a project in which I have to use RFID reader to scan cards. In this project I have used it for for s ...
Hi friends, I hope you are fine and having fun. In my last article, we have discussed Squirrel Cage Induction Motor which is a type of 3 Phase Induction Motor. Today, I am going to tell you about a Wound Rotor Induction Motor , which is also a type of 3 phase induction motor. This motor is the one which uses a wound rotor. I will tell about the construction of a wound rotor later in this article. A Wound Rotor Induction Motor is also known as slip ring induction motor.
I will tell you about the construction of Wound Rotor Induction Motor in the first section. In the second section, I would be throwing light on the operation and working principle of Wound Rotor Induction Motor. After that, I will tell you some of the key features and uses of Wound ...
Hi Friends! Happy to see you around. Thank you for clicking this read. In this post today, I’ll document a detailed guide on the PCB fabrication process.
PCB is commonly used in modern electronics. If you uncover the TV set and have a look inside, you’ll find a printed circuit board, electrically connecting components on the board. There are copper traces incorporated on the board to electrically connect the components and provide the current flow from one part to another.
These printed boards make devices precise and compact that are capable of doing more functions than the devices where the end to end wiring is used.
Circuit boards are divided into three main types. Let’s discuss each type one by one so you can better understand the structure ...
In today's post, I am gonna share a new Arduino Library for Seven Segment Display. In my recent project, I got a chance to work on seven segment displays, I have worked on them using PIC microcontroller but haven't got a chance to use them with Arduino. So, now as usual when I started working on them, I started searching for Arduino Library but I kind of got disappointed after getting quite heavy libraries for seven segments, and after a lot of search I thought of designing my own Arduino library for seven segment display, which I am gonna share in this post. :)
It's not very advanced library as we know seven segment displays are not too complex, so its quite simple and using it you can quite easily display any numerical digit on the seven segment ...
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 ...
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
Hello Everyone! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino Uno WiFi Rev 2.
Arduino Uno WiFi Rev 2 is a microcontroller board based on ATmega4809 and carries an ECC608 crypto chip to ensure a secure and safe WiFi connection. The board contains 14 digital I/O pins, 5 PWM pins, 6 analog pins, one SPI protocol, one I2C, and one UART communication protocol.
I suggest you read this entire post till the end as I’ll detail the complete Introduction to Arduino Uno WiFi Rev2 covering pinout, pin description, features, programming, and applications.
Let’s jump right in.

Hello Everyone! Happy to see you here. I welcome you on board. In this post today, I’ll be discussing the Introduction to BC558.
BC558 is a bipolar junction transistor used for amplification and switching purposes. It belongs to the PNP transistor family and is available in a TO-92 package. It contains collector current 100mA, indicating it can drive load under 100mA.
I've previously detailed the Introduction to BC640 & BC327.
I suggest you read this entire post as I will cover a complete introduction to BC558 explaining pinout, working, power ratings, physical dimensions, datasheet, and applications of BC558.
Let’s jump right in. Continue reading.

Hi Friends! Hope you are doing well. Today, I'll discuss and highlight the main question relating to VPN - Should You Build Your Own VPN From Scratch?
We all know how important and valuable VPNs are. Using them to get Netflix’s or Amazon’s full catalogs is one thing, but the security benefits are vital. Without a VPN, your data is up for grabs. And while a VPN cannot fix all the privacy issues of our current reality, it does make you more difficult to infiltrate than most others. You should also have a look at How to use VPN, if you are not already aware of.
Should You Build Your Own VPN From Scratch?
Subscribing to a VPN service is easy and not all that expensive, but if you want control over your VPN, making your own might be the best option ...
We all know technology is not only changing trends and habits, but it is also reshaping the way we live our daily lives. We are not talking about centuries ago, but even if we examine the previous two decades, everything, from our communication style to our travel means, from our shopping habits to our entertainment industry, is changing rapidly, and this has both pros and cons. In a broader view, we can say that positive impacts are more dominant than negative effects on our lives. Maybe you have the opposite opinion, but I can prove this with the help of a simple and general example that I am going to discuss in detail with you. Just like almost every other sport and game, poker has some visible technical changes, and people can play poker online. Clients and casinos are getting more and ...
