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. In this tutorial, we will learn how to interface the BMP280 sensor with the ES32 module to get temperature, pressure and altitude readings. Later, in this tutorial, we will also discuss how to upload these sensor readings to a web server.
BMP280
BMP280 or Barometric pressure sensor is a module used to measure temperature pressure and altitude. The small size and low power consumption feature of this sensor makes it feasible for battery-powered devices, GPS modules and mobile applications etc.

The BMP280 is the product of BOSCH which is based on Bosch’s proven Piezo-resistive pressure sensor technology featured with high accuracy, long term stability, linearity and high EMC robus ...
The Industry 4.0 market size will reach $267.01 billion by 2026. Industry 4.0 depends on the secure, fast, and cost-effective data transfer between IoT devices. IoTA is designed to ensure secure communication between two devices within the IoT(internet of things) framework. Let's have a detailed look at the role of IoTA in industrial IoT.
Understanding IoTA- how it's different from blockchain
The terms MIOTA and IoTA together make up the term IoTA. While MIOTA is a cryptocurrency, IoTA is a non-profit foundation. Since its inception in 2015, IoTA has formed joint ventures with firms like
Fujitsu
Samsung
Telekom
Volkswagen
IoTA is technically different from blockchain in terms of the underlying technology. IoTA works on a technology ca ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a webserver in raspberry pi. We also looked at configuring addclient and deploying apps to our repositories. This tutorial will teach us to set up a free media server on Raspberry Pi.
Using a Raspberry Pi as a multimedia server requires:
An operating system and miniDLNA program installed on your Raspberry Pi,
You can attach various cleanly formatted and fragmented hard disks to your Raspberry Pi for storing and streaming media files.
A basic understanding of how to use a computer, Client-server architecture skills, familiarity with Unix terminal and Secure shell, and a passion for computing and the media are a must!
Even if you ...
Hello readers, I hope your all are doing great. We know that a Raspberry Pi Pico module comes with multiple inbuilt features for example onboard memory, processing units, GPIOs or General Purpose Input Outputs (used to control and receive inputs from various electronic peripherals) etc.
In our previous tutorials, we discussed how to access GPIO pins of the Raspberry Pi Pico module for both input as well as output operations.
In this tutorial, we are going to discuss another important feature of the Raspberry Pi Pico module (RP2040) which is Dual Core Processor. The Pico board features with 133MHz ARM Cortex-M0+, Dual Core Processor. This dual-core feature makes the Pico module capable of multiple thread execution or multithreading.
Now before writing the MicroPython program let’s first un ...

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 ...
Hi friends. Today we are going to go through one of the most commonly used topics in writing ladder logic programming which is using comparator operations. This includes the logical and mathematical comparison between variables to decide where the logic goes.
There are many comparator operations like equal (==), not equal (<>), less than (<), greater than (>), less than or equal (<=), greater than or equal (>=). All these comparator operations might be used in different logic scenarios while writing a ladder logic program. In this tutorial, we are going to go over each operator showing the input operators and output as well. In addition, we will practice some examples with the simulator to familiarize how to use them flexibly whi ...
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython.
Introduction
Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a ...
