Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4. This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work.
What is time-lapse?
When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras.
Components
Raspberry pi 4B
Pi camera
Connect to the Raspberry Pi
Cameras that can be used with the Raspberry Pi are a bit limi ...
Hi friends, today we are going to explore mathematical computations in ladder logic. Like in any programing language you should find logic and mathematic computations, here in PLC programming you often need to process the input data that is collected from reading analog devices like temperature, level, flow et cetera. Then you need to run some calculations on this data to derive some other variables for deciding to run or stop some device or even to determine analog output to output to analog device i.e. valve or actuators. In the following sections, we are going to explore the mathematical functions and their input operators and outputs as well. Then we will show how to utilize such functions in ladder logic with simple examples and as usual enjoy practicing them thanks to the PLC simula ...
Welcome to the next tutorial of our Raspberry Pi programming course. In our previous tutorial, we learned how to create a timelapse video with still images and understand how phototimer and FFmpeg work. In this lesson, you'll make a button-controlled "music box" that plays different sounds depending on which buttons are pressed.
What you will learn
Connect button pushes to function calls using the Python gpiozero package and uses the Python dictionary data structure
Components
Raspberry Pi
Breadboard
Buttons
Jumper wires
Speaker
Set up your project
For this project, you'll need some audio samples. On Raspbian, there are many audio files; however, playing them with Python can be challenging. You can, however, transform the audio files ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
Hello readers, I hope you all are doing great.
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT.
Project Overview
In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32.
Fig. 1
To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD).
We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to displa ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to tweet from Raspberry pi. We also discussed some methods used by the tweepy library to perform some API calls in our project. We will learn how to print from a Raspberry pi in this lesson.
Let us get started
There are several benefits of having a print server. Print servers may link numerous computers to one or multiple printers, either physically or wirelessly, allowing you to access the printer with various devices and send print instructions from all the other connected computers.
It is not easy to print from an Android smartphone to a cabled printer; however, a printer server makes it simple. A print server is useful in small workpl ...
Hi Friends! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through the Top 10 Workflow Automation Software.
Running a business is not an easy job. It requires a lot of deliberate effort and careful attention to run business processes successfully. Some tasks involved are repetitive and time-consuming, making it difficult for you to do them manually. This is where workflow automation comes in handy that doesn’t require human intervention and can be used to effectively manage and execute business processes.

Hi guys! Hope you’re well today. In this post today, I’ll cover What is Industrial IoT (Internet of Things?)
IIoT is now a talk of mainstream conversation. This term has blown up in the past couple of years. Before we move further to describe IIoT, it is evident that industries are no longer dependent on the traditional production processes that happened to be costly and guaranteed no optimal results. Now companies are willing to incorporate automation in manufacturing and production processes. Smart systems, no doubt, are dangerous for the traditional labor workforce, but on the other hand, they create more opportunities for the people equipped with the latest business trends.
Curious to know more about Industrial IoT, how does it work, the difference between IoT and IIoT, examples of II ...
to our new beginner’s course on Raspberry Pi. This course is appropriate for anyone using either a traditional Raspberry Pi board or the new Raspberry Pi 400 board that includes an integrated keyboard and display. Learning how to code, building robots, and doing plenty of other strange and exciting things are all possible with this low-cost computer setup. The Raspberry Pi can do everything a computer can do, from surfing the web to viewing movies and music, and playing video games.
Raspberry Pi is much more than a modern computer. It`s created to educate young people on how to program in languages such as Scratch and Python, and it comes with all of the major programming languages pre-installed. The world is in desperate need of programmers now ...
Hello, friends today we will discuss the basic concept of chemistry it is our first tutorial series in which we will discuss:
Atom
Molecule
Ion
Molecular ion
Now in this article, we will discuss atoms. Its definitions, examples, properties, its evolutionary history, and also some important facts in the form of questions.
Atom
Definitions
A tiny particle that cannot be seen with a naked eye so-called atom.
Or
Atom is the lowest unit of matter and is often divided without the discharge of electrically charged particles.
Or
Atom is the introductory structure block of chemistry.
Examples
From molecule;
Hydrogen (H2)
It has two atoms.
Nitrogen (N3)
It has three atoms
From elements;
Helium(He)
It has two electron
Properties
We discuss different properties of atoms ...
