Hi, my friends and welcome back. I am happy to meet you again with a new tutorial of our PLC ladder logic programming series tutorials. Today we will complete what we started the last tutorial on the Elevator control project. We have a bunch of duties to complete together today. So let’s save time and jump into work immediately.
Project description:
Figure one shows the details that might help me describe the project between our hands. We have an elevator car that travels up and down and can stop on one of four floors based on the passengers’ requests. We have 6 push buttons on the wall next to the elevator door that can send requests to call the elevator. In addition, there is a control panel inside the elevator cabinet in which there are push buttons to request stations to reach floors ...
There is a deep sense of wonder in how a light bulb works. Although most people understand the function of a light bulb, not many appreciate the physics in how it converts electrical energy into light. The quantum physics behind this basic technique can help explain why some bulbs explode.
The operating principle behind a light bulb
The first step to getting a light bulb is to connect it to an electrical source. The filament in the bulbs burns and becomes hot. Because hot objects glow, the filament will become a light source.
The hotter it becomes, the brighter the light, thus the whiter it becomes. However, the filament on its own will eventually burn out and cease to create light. The presence of air, especially oxygen, causes a chemical reacti ...
Hello friends, I hope you all are fine and enjoying your lives. Today, I am going to share a comparison titled Arduino Vs Raspberry Pi. Actually, I have been receiving a lot of emails and comments from new engineering students that "we are new in embedded and we want to start our project so please tell us which one is better Arduino or Raspberry Pi?" So, I thought to write a post on Arduino Vs Raspberry Pi and in this post, I am going to make a detailed comparison between the two and will let you know, which one you should use in your project and why?
So, I hope that you are all aware of or at least have heard about these two boards, which are Arduino and Raspberry Pi. If you haven't heard yet then you must have a look at Arduino Official Site and ...
Designing homes and landscapes is a dream job for many individuals, but the challenges of becoming a licensed architect often stand in the way of this dream. To become a licensed architect, you’ll need to be willing to put in a lot of hard work throughout the education and apprenticeship stages of certification and study extensively for the ARE accreditation exam. Once certified, many individuals choose to work for a residential architectural firm to design custom homes and assist with planning remodeling projects.
There are many education and experience requirements involved with qualifying for the ARE exam and becoming a residential architect. In this article, we’ll go over the details for each of these requirements and answer some of your quest ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Reduce the File Size of Videos in Various Ways. Videos are known to have large file sizes that can range into several gigabytes. The longer the video and the higher its quality, the larger its file size tends to be.
The fact that videos are so large can pose a lot of problems. Not only will they take up more storage space, but transferring them can present more of a challenge as well. That is why it can be helpful to know how to reduce the file size of your videos, in a number of different ways.
How to Reduce the File Size of Videos in Various Ways
Let's have a look at How to Reduce the File Size of Videos in Various Ways. All these ways are mentioned ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am gonna design a Convolution Calculator in MATLAB. We all know about convolution but if you don't know then here's the wiki page for convolution which has a detailed description of Convolution. In simple words, convolution is a mathematical operation, which applies on two values say f and g and gives a third value as an output say v. In convolution, we do point to point multiplication of input functions and gets our output function.
Convolution is an important technique and is used in many simulating projects. It has a vital importance in image processing. So, today we are gonna do convolution in MATLAB and will check the output. You should also check Image Zo ...
You can use a multimeter to figure out what's wrong with the electrical system in your car. Most of the time, if you check for voltage and continuity, you can figure out where the problem is coming from. This article will show you how to use a multimeter on a car.
First, make sure the multimeter isn't on. Then connect the positive lead to the positive terminal on the battery. Connect the negative lead to a metal piece on the frame of the car. The last step is to turn on the multimeter and read the results. If it says 0 volts, it means that no electricity is moving through the circuit. If the voltage is 12 volts or more, then there is a current in the circuit.
A multimeter can be helpful if you can't figure out what's wrong with your car's electrics. You should be able to fix many c ...
Hello friends, hope you all are fine and having fun in your lives. Today, I am going to share Top 3 PIC C Compiler. We all know about PIC Microcontrollers because of which now we can quite easily add complex automation in our projects. So, today, I am going to share C compilers for PIC Microcontrollers. When an engineer starts working on some engineering project then he must have to choose a microcontroller. PIC is most commonly used Microcontroller in engineering projects. So, now when you have selected that you are gonna use PIC Microcontroller in your project then there comes a need which compiler to use for designing programming code for PIC Microcontroller.
It's quite a difficult as well as important decision because I have seen that once you ...
Hello friends, I hope you all are doing great. In today's tutorial, I am gonna discuss How Point-to-Point Tunneling Protocol (PPTP) Works. Online security is more important than ever. With hackers and brute force attackers, it feels like your private data is constantly at risk. One way to protect your security online is by using a VPN.
VPNs may use several protocols. These protocols are like the language that's used by your computer and the VPN server as they communicate. Some protocols are faster than the competition while others prioritize security.
One of the oldest, yet still popular, VPN protocols is Point-to-Point Tunneling Protocol, or PPTP. It was introduced in 1995, and though newer protocols have since usurped its place as the greatest, ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new tutorial which is Interfacing of Flame Sensor with Arduino. I have recently posted a tutorial in which I have shared the Flame Sensor Library for Proteus. Now in this tutorial, I am gonna use that Flame Sensor Library and will interface this Flame Sensor with Arduino. So, if you haven't downloaded this file then I suggest you to download this Flame Sensor Library so that you can easily simulate this flame Sensor in Proteus.
I am sharing interfacing of this Flame Sensor with Arduino today, but soon I will also post a tutorial on Interfacing of Flame Sensor with PIC Microcontroller. If you guys have any questions then ask in comments. I have also ...
