Hi Everyone! How are you doing, my friends? Today I bring a crucial topic for PLC programmers, technicians and engineers. We have been working together for a long time using ladder logic programming. We have completed together dozens of projects from real life and industry. One day I was thinking about what we have done in this series of ladder logic programming, and I came across that I missed talking about one essential topic ever. You know what? It’s the PLC troubleshooting and online debugging! After writing a ladder logic program for the project, you can imagine it should operate from the download moment 24/7. As usual, any system goes faulty one day. So we need to go through this matter, showing you how to find our PLC faults, troubleshoot, and go online with the PLC to figure out th ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new project named LPG Gas Leak Detector using Arduino in Proteus ISIS. Before reading this tutorial, you must first download the Gas Sensor Library for Proteus because we are gonna use that Library and will simulate the Gas Sensor in Proteus.
In this library you will find eight sensors and all of them works exactly the same so that's why we are gonna use one of them. For LPG Gas Leak Detector Project I have used MQ-2 sensor which is used for detection of LPG gas. I have also used Arduino UNO board which you can simulate in Proteus using Arduino Library for Proteus. Moreover, I have also placed an LCD which will display either LPG gas Leak Detected or ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to 20N60. 20-N-60 is basically a power Metal Oxide Semiconductor Field Effect Transistor (MOSFET). Power MOSFET is a device that can handle a specific level of power. I have already shared information about MOSFET in my previous tutorials e.g. Introduction to 75N75, SG3524, 50N06, IRFZ44N, C945 and TL072. Before going into the details of this article you must have a look at these articles. They will result in the better understanding of this article.
MOSFET family is divided into two categories. P-channel MOSFET and N-channel MOSFET. 20-N-60 belongs to the N-channel MOSFET. It is based on United Technologies Corporat ...
Hello Pupils! I welcome you to the board. I hope you are fine. In today's tutorial, we will design a project Metal Detector using 555 Timer in Proteus ISIS. All of us perceive the situations when at the public places such as on airports or in shopping malls where sharp metallic objects such as a knife or illegal guns or even a nail cutter are not allowed, there are walkthrough gates at every entrance so that any person with the forbidden material when passes through the gate, the alarming buzzer automatically switched on. This happened because the walkthrough gates have the Metal Detector circuit in them that works immediately when such a situation occurs.
In this session, we'll learn:
What are Metal Detectors?
How does the 555 Timer collabor ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about How to Reset Arduino Programmatically. Sounds a bit weird, yes it is :) but literally in some cases, this technique is the only choice you have. It recently happened to me in one of my projects, that's why I know How important it is. Before going into details, let's first have a look at the resetting feature of Arduino.
If you have worked on any Arduino board, then you must have noticed the RESET pin in Arduino and you may wonder what's the use of this pin. So, today this pin is gonna get useful. Moreover, you have also noticed that when you upload the code to your Arduino board then the Arduino resets, another way of resetting Arduino is by opening the Seri ...
Hello friends, i hope you all are fine and enjoying. Today i am going to share a new tutorial in which I am gonna explain What is 555 timer? We all know about 555 timer, which is an 8-pin IC (integrated circuit), most commonly used in electronic projects, built now a days. As you can see fron its name that it is a timer and designed to generate PWM.
In today's tutorial i am going to explain, what's hidden inside this 555 timer IC and what is 555 timer. A 555 timer is a much compatible electronic device and the biggest feature of this IC is that it able to work on both analogue and digital techniques. Now if we simply consider the output of the 555 timer then, at any particular time, this timer has only 1 definite state. Which means at any time, it ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Atmega32. ATmega32 is eight-bit higher enactment microcontroller, it is manufactured by an Atmel (it is a designer and builder of different semiconductors materials). It is founded on enriched RISC which stands for (Reduced Instruction Set Computing) design which consists of 131 (one thirty-one) potent commands.
Mostly commands implement in one mechanism sequence. The maximum frequency at which it operates sixteen MHz. It delivers a subtle equilibrium among enactment and balance. It is the Pico Power sort of the normal ATmega328 kind which permits it to work below lesser voltage and power necessities, nearly 1.62 volts. In today’s post, we will have a look at its fort ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project which is an Up-Down counter. Most of us who have an electronics background or studied digital electronics must know the counter. Counter is a simple device which counts numbers. As per the digital electronics, there are two types of counter, the Up counter which counts in increasing order and another is Down counter which counts in decreasing order. And every counter has a reset limit, on which the counter resets to its initial value and starts the counting again. The limit of every counter depends on the bits of counter. For example, we have a 8 bit Up counter which means it will count upto 255 and afterwards it will reset and will start agai ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hi Guys! I welcome you on board. In this post today, we’ll discuss the KSC1845 NPN Transistor. We will have a look at the KSC1845 Datasheet, Pinout, Power Ratings, Equivalents & Applications in detail. As it's an NPN transistor, electrons are the majority charge carriers and thus play a major role in conductivity. KSC1845 is mainly used for fast-switching and amplification purposes.NPN transistor carries 3 terminals, known as:
Emitter
Collector
Base
If the applied voltage at the base terminal exceeds 0.7V, it will forward bias this NPN transistor and the current will start to flow from Collector to Emitter. If the base voltage is less than 0.7V, KSC1845 will remain in the reverse-biased state.
I suggest you buckle up as I’ll discuss the KSC1845 ...
