Hello, my friends and welcome back with one new tutorial of our ladder logic programming series. Today I am bringing one exciting project which you can see everywhere, in your home, work, and public places, which is an elevator. We will design a solution using plc ladder logic programming, which drives the elevator. Our elevator is composed of 4 floors and has all capabilities of large-scale elevators. So let’s get started and save time and jump into our tutorial.
Elevator Project
As you can see, Everyone figure 1 depicts the complete scene of the project and tells that the elevator we will manage has four floors to visit. On the first floor, there is only one outer request to call the car from any floor above, i.e. from floor 2, floor 3, or floor 4. While on the second floor, there are ...
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 ...
Hi Guys! Hope you’re well today. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to B772.
B772 is a medium power bipolar junction transistor mainly used for switching and amplification purpose and belongs to the PNP transistor family. It comes in the TO-126 package and carries a collector current of 3A which means it can support load under 3A. The 60V is the collector-base voltage and 30V is the collector-emitter voltage while 5V is the emitter-base voltage which means it requires 5V to bias the transistor and start transistor action.
In this post, I’ll be discussing pinout, datasheet, working principle, power ratings, physical dimensions, and applications of B772.
Let’s get started.

Hello Friends! Happy to see you around. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n4749.
The 1n4749 is a Zener diode made of silicon material. It is used for clipping circuits with high power ratings. It is also incorporated in voltage stabilizing circuits and voltage protection circuits. There is a slight difference between the normal diode and the Zener diode. In the normal diode, conduction is carried out in one direction only i.e. in forward biased condition. While in the case of the Zener diode, the conduction is carried out in both conditions i.e. forward biased condition and reverse biased condition. Zener diodes are also applied to keep circuits from overvoltage.
Read this post till the end as I’ll walk you through the complete Int ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new PC817 Library for Proteus. PC817 is an optocoupler / optoisolator, which is used for electrical isolation between components or modules. It's normally used after Microcontroller Pins so that back emf doesn't burn them. You should also have a look at Introduction to PC817, I have shared its complete details there.
PC817 is used a lot in Embedded projects but is not available in Proteus, so our team has designed it for the first time. Using this Library, now you can easily simulate this optocoupler in your Proteus simulations. So, let's get started with How to download & install PC817 Library for Proteus:
PC817 Library for Proteus
First of all, downl ...
Hi Guys! Hope you’re well today. In today's tutorial, we will have a look at the 2SC1345 NPN Transistor. We will also discuss 2SC1345 Datasheet, Pinout, Power Ratings, Equivalents & Applications. As this is an NPN transistor, the conductivity is mainly carried out by electrons as the major charge carriers. 2SC1345 is mainly used for switching and amplification purposes.Let's first recall NPN transistors: NPN transistor comes with 3 terminals, named:
Emitter
Collector
Base
If the voltage at the base terminal is above 0.7V, the NPN transistor gets forward biased & starts conducting i.e. current will flow from the Collector to Emitter terminal. If the Base voltage is less than 0.7V, it remains reverse-biased.So now let’s get started with the 2SC1345 NPN Transistor.
2SC134 ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to DS18B20. DS18B20 is a temperature sensor that can measure temperature from -55oC to +125oC with an accuracy of +- 5%. It follows 1 wire protocol which has revolutionized the digital world. Because of its 1 wire protocol, you can control multiple sensors from a single pin of Microcontroller.
DS18B20 is normally used in industrial projects where high accuracy is necessary. I will give you a detailed overview of this temperature sensor in today's post where we will have a look at its Pinout, working, protocol, etc. I will also share some links to projects where I have interfaced it with Arduino or other microcontrollers. If you have any questions, please ask in comment ...
Hello Friends! I hope you are well. Today, I am going to give you a detailed Introduction to NPN transistor. In this tutorial, we'll look at the NPN transistor, how it works, circuit diagram, output characteristics curve, and applications. It is a bipolar junction transistor mainly used for current amplification and switching purposes.
BJTs (Bipolar Junction Transistor) are divided into two types i.e. NPN transistor and PNP transistor. Both transistors are different in terms of their electrical composition and construction, however, both are used for amplification and switching purposes in one way or the other.
What is NPN Transistor?
NPN transistor is a bipolar junction transistor(BJT), composed of 3 semiconductor layers in a way that o ...
