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.

Welcome to the second chapter of our beginner's course on the Raspberry Pi. In the previous tutorial, we learned about the components of this little computer. We also considered its uses, as well as the most important advantages and disadvantages. Let's get started with setting up our little computer to run the Raspbian operating system in this lesson.
How to Install Raspbian using an imager
The next step is to make sure you have your board and SD card. The Raspberry Pi has an operating system because it is a full computer. For those who prefer a GUI desktop experience, a headless mode is still an option. Most people use Raspbian, a Debian-based operating system tailored specifically for the Raspberry Pi. However, there are other options. An exce ...
Hello readers, I hope you all are doing great. This is the first tutorial of our Raspberry Pi programming series. In this tutorial, we are going to provide a brief description of the Raspberry Pi Pico module designed and developed by the Raspberry Pi organization itself. We will also discuss various features, memory, peripherals interfacing capabilities, hardware architecture, programming techniques etc.
Before moving towards the detailed study of the Raspberry Pi Pico module, let’s first understand the traditional Raspberry Pi Computers.
What is Raspberry Pi?
Raspberry Pi is a single-board computer or a minicomputer. It was created with the goal of making computing knowledge more accessible to those who cannot afford laptops or desktop computers ...
Hello friends, I hope you all are doing great. Today, I am going to share the 6th tutorial of Section-III in the Raspberry Pi Programming Course. In our previous tutorial, we have seen how to interface an Ultrasonic Sensor with Raspberry Pi 4 and used Python to perform its calculations. In today's tutorial, we'll discuss how to interface a DHT11 temperature and humidity sensor to a Raspberry Pi. So, let's get started:
ComponentsHere's the list of components, we are going to use in today's circuit:
LCD display
DHT11 sensor
Raspberry pi
Breadboard
Male-to-female jumper wires
What is a DHT11 sensor?
DHT11 is a low-cost digital sensor, used to measure temperature and humidity in the surr ...
Hello friends, I hope you all are doing great. Today, I am going to start a new tutorial series on Raspberry Pi 4. It's our first lecture today, so I will explain the basics of Raspberry Pi boards. In this tutorial series, I will teach you each and everything about Raspberry Pi and its programming. I have designed this guide for beginners, so we will start from the very basics and will slowly move toward complex concepts. Python programming language is used in Raspberry Pi boards, so we will study Python as well. So, we will learn both programming and hardware circuit designing in this tutorial series. Let's first have a look at What is Raspberry Pi?
What is Raspberry Pi?
Raspberry Pi is a series of Single Board Computer, developed by the Raspberry Pi Foundation in England, to teach co ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at LED Blinking using Raspberry Pi 3. It's our first embedded project on Pi 3 and its quite simple. In our previous tutorials on Raspberry Pi 3, we have seen How to install Rasbian on SD Card for Pi 3 and then we have also setup HDMI LCD with Pi 3. So, now our raspberry Pi 3 is ready to program.
In today's tutorial, we will interface a single LED with digital Pin of Raspberry Pi and then we will design a simple code in Python which will turn this LE ON and OFF. It will be quite simple and I will guide you step by step, but if you got into any trouble then ask in comments and I will help you out. So, let's get starteed with LEd Blinking using Raspberry Pi 3 ...
We learned in the previous tutorial how to connect a joystick to a Raspberry Pi 4 using an mcp3008 and an op-amp IC, the LM324A. For each of the interface methods we studied, we created a python script allowing us to interact with the circuit. This tutorial will show you how to connect a 4-channel relay module with a Raspberry Pi to carry out switching.
A relay's primary function is to allow a circuit to be controlled by a weak signal. High-current applications necessitate relays to separate the low-voltage control circuit from the high-power driving circuits. Because of this, understanding it is crucial for those interested in industrial or household automation.

We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. I will show you how to install and connect the RFID card chip to your Raspberry Pi through step-by-step instructions.
Modern security systems would only be complete using radio frequency (RFID) devices. To control who can enter a facility or which rooms they can access, RFID chips and card readers are employed. The RFID card's unique identification number can be read wirelessly with a wall-mounted RFID reader. A door will only unlock and allow entry if the RFID card's unique identification number matches a list of approved cards.
It's fun to tinker with this circuit, and it may be used in many other applications, from opening locks to taking a ...
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 friends, I hope you all are doing well. Welcome to the 11th tutorial of our Raspberry Pi programming course. In the previous chapter, we have seen how to regulate the speed of a Stepper motor with Raspberry Pi 4. Today, we'll work on the servo motor and will control it with RPi4. So, let's get started:
Components Required:We will need the following components to control Servo Motor with Raspberry Pi 4:
