Hello friends, I hope you all are doing great. In today's tutorial, I am going to create the first Ladder Logic Program in PLC Simulator. It's 3rd tutorial in our Ladder Logic Programming Series. In our previous tutorial, we have installed PLC Simulator and now we can say our lab is ready to learn and practice. So let us get to work and get familiar with the ladder logic components.
After this article, you will have a complete understanding of PLC contact and coil including their types and possible causes. Because they are the building block of any rung of a ladder logic program. So let us start with ladder logic rung components.
Ladder Logic Contact/Input
In ladder logic programming, a contact represents the input of the system and it could b ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am going to share How to do USB Communication between Android and Arduino. I have designed many projects before in which I have interfaced Android and Arduino and communicated between them but in those projects I have used either Wifi or Bluetooth as a mode for communication. But recently I got a project in which I have to do USB Communication between Android and Arduino, they have this restriction of using USB. So, I have to work on it and I got it working successfully. You should also have a look at How to Install Android Studio. and Getting Started with Android.
So, today I thought to share it with you guys. It isn't much difficult but will need a little pa ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to print from a Raspberry pi. We also discussed some libraries to create a print server in our raspberry pi. We will learn how to take screenshots on Raspberry Pi using a few different methods in this lesson. We will also look at how to take snapshots on our Raspberry Pi using SSH remotely.
Why should you read this article?
This article will assist you when working with projects that require snapshots for documenting your work, sharing, or generating tutorials.
So, let us begin.
Screenshots are said to be the essential items on the internet today. And if you have seen these screenshots in tutorial videos or even used them in regular commu ...
Hello readers, hope you all are doing great. In this tutorial, we will discuss low power modes in ESP32, their purpose and their implementation to increase the battery life by reducing power consumption.
Purpose of Low Power Modes
Fig.1
Along with multiple wireless and processing features, ESP32 also provides us with a power-saving feature by offering sleep modes. When you are powering the ESP32 module from the live supply using an adaptor or a USB cable, there is nothing to worry about power consumption. But when you are using a battery, as a power source to ESP32, you need to manage the power consumption for longer battery life.
Low Power Modes in ESP32
When ESP32 is in sleep mode, a small amount of power is required to maintain the state of ...
Hi Guys! Hope you’re well. I welcome you on board. Thank you for viewing this read. In this post today, I’ll walk you through the Introduction to BC557.
BC557 is a bipolar junction transistor with DC current gain 300. It falls under the category of PNP transistors where one N-doped layer stands between the two P-doped layers. The continuous collector current is 100mA means it can drive load under 100mA. BC557 comes in the TO-92 package and is mainly used for switching and amplification purpose.
Before I bore you to tears, let’s dive in and read the complete introduction to BC557 covering datasheet, pinout, working principle, power ratings, physical dimensions, and applications.

In today's digital age, where technology is an integral part of our daily lives, it's crucial to be aware of the various cybersecurity threats and take appropriate measures to protect ourselves.
While many people are familiar with the more well-known threats like phishing scams and malware, several commonly overlooked cybersecurity risks can have significant consequences. In this article, we will explore these threats and provide insights on how to overcome them.
What are the most important threats that we cannot afford to ignore?
One of the commonly overlooked cybersecurity threats is the vulnerability of public Wi-Fi networks. In an increasingly connected world, we often rely on public Wi-Fi hotspots in cafes, airports, and other public pl ...
XBee modules have become a cornerstone for wireless communication in today's electronics and embedded systems projects. Whether you are building a home automation system, an industrial control network, or simple point-to-point communication between devices, XBee offers a reliable and easy-to-use solution. In this comprehensive introduction, we will explore what the XBee module is, how it works, its core features, and how you can integrate it into microcontroller-based projects.
In future tutorials, we’ll delve deeper into specific interfacing guides, including how to interface the XBee module with a computer and connecting XBee to an Arduino. While Arduino will be our primary focus due to its popularity and accessibility, you can also connect XBee modules to other microcontrollers such as ...
Every engineer has stared at a script in their IDE and thought, “This works… but I wonder if it could do more?” That small piece of code, a side project, or a utility you built for fun could be the seed of a full-fledged business. The problem is, writing good code is only the first part of it all. Turning it into a product that generates revenue requires thinking beyond functions and algorithms.
Many engineers struggle with this transition because the skills that make a great coder don’t always translate to business strategy, marketing, or legal compliance. You can have an elegant solution, but without understanding the market, protecting your intellectual property, and setting up a proper business structure, that code might never reach paying customers.

Hi Friends! I hope you are doing fine. Today, I am going to give you a detailed Introduction to Arduino Nano. We will also discuss Arduino Nano Pinout, datasheet, drivers & applications. It is a Microcontroller board developed by arduino.cc and based on Atmega328p / Atmega168.
Arduino boards are widely used in robotics, embedded systems, automation, Internet of Things(IoT) and electronics projects. These boards were initially introduced for students and non-technical users but nowadays Arduino boards are widely used in industrial projects.
Any kind of technical support and help is readily provided by the Arduino community. I have also designed this video tutorial on Arduino Nano:
Here's the figure showing the key points of Arduino Nano:

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to ADC0804. In electronic engineering different modules used to conversion of analog signal into a digital signal. These tools are recognised as analog to digital converter or ADC. Thes signal converter also used to find the value of input current and voltage. Normally the output of these converters are 2 binary numbers but other values are also possible. These analog to digital converter are available in different structure scheme but mostly they are available in integrated circuits packaging.
The working ability of these signal converter depends on their bandwidth and signal to noise ration (SNR). Their bandwidth can be fined by their sample r ...
