Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Control DC Motor with Raspberry Pi 3. We will control both the speed and direction of DC Motor. I hope you have read the previous tutorial on How to Create a GUI in Raspberry Pi 3 as we are gonna create a small GUI in this tutorial as well and then we are gonna control our DC Motor with Buttons on GUI.
In order to control the DC Motor, we have to use some drivers in between our Microcontroller and DC Motor. This driver's functionality is to control a 12V DC Motor with a 5V signal from a microcontroller. In today's tutorial, we are gonna use L298 Motor Driver. So, let's get started with How to Control DC Motor with Raspberry Pi 3:
How to Control DC Mot ...
Our next step in the Raspberry Pi training program is to get zero tiers up and run on a Raspberry Pi 4. How to utilize a Raspberry Pi to measure internet speed and store the results in Grafana or Onedrive was the topic of the last piece. During the project, you will discover how to install ZeroTier on a Raspberry Pi and get it up and running. We will also learn how to set up a firewall to secure our network.

What is zeroTier
ZeroTier is a software that provides a streamlined web-based interface for constructing virtual networks connecting various gadgets. Somewhat akin to configuring a virtual private network on a Raspberry Pi, these networks exist only in cyberspace. The process o ...
Hi Friends! Hope you’re well. In this post today, we’ll discuss What is Raspberry Pi Zero? We’ll also cover Raspberry Pi Zero Pinout, Specs, Projects & Datasheet.
Developed by Raspberry Pi Foundation, Raspberry Pi Zero is a tiny single-board computer, initially introduced to teach basic computers in schools. Later, it rose to popularity due to its low cost and open source design. Now it is widely used in robotics and embedded systems to develop IoT projects. This device is among the bestselling British single-board computers. I suggest you read this post all the way through as I’ll cover Raspberry Pi Zero in detail. Let’s get started.

Raspberry Pi Zero(released in Nov 2015, by Raspberry Pi Foundation) is a sin ...
Welcome to the next tutorial of our Raspberry Pi programming tutorial. The previous tutorial showed us how to Interface weight sensor HX711 with pi 4. We learned that a weight sensor HX711 and load cell could be easily interfaced with a Raspberry Pi 4 with careful attention to wiring and software configuration. However, now we're one step ahead of that by using the Internet as the wireless medium to transmit the message from a Web browser to an LCD screen attached to a Raspberry Pi. This project will be added to our collection of Internet of Things (IoT) projects because messages can be sent from any Internet-connected device, such as a computer, smartphone, or tablet.
A bulletin board serves as a vital means of communicating and collecting information. Notice boards are common at many pu ...
During the era of Covid-19, social distancing has proven to be an efficient method of reducing the spread of contagious viruses. It is recommended that people avoid close contact as much as possible because of the potential for disease transmission. Many public spaces, including workplaces, banks, bus terminals, train stations, etc., struggle with the issue of keeping a safe distance.
The previous guide covered the steps necessary to connect the PCF8591 ADC/DAC Analog Digital Converter Module to a Raspberry Pi 4. On our Terminal, we saw the results displayed as integers. We dug deeper into the topic, figuring out exactly how the ADC produces its output signals. In this article, however, we will use OpenCV and a Raspberry Pi to create a system that can detect when people are trying to avoi ...
Hi Guys! I welcome you on board. In this post today, we’ll study What is Raspberry Pi Pico? We’ll also detail Raspberry Pi Pico Pinout, Specs, Projects & Datasheet.
Raspberry Pi Pico is a little different from other modules introduced by Raspberry Pi Foundation. This unit is similar to Arduino Nano and is called a microcontroller board that incorporates a powerful RP2040 chip. This is different from other single-board computers that fall under the Raspberry Pi series. It is not a computer but a microcontroller board.
I suggest you buckle up as I’ll explain Raspberry Pi Pico in detail.
Let’s get started.
What is Raspberry Pi Pico?
Raspberry Pi Pico is a microcontroller board (released on 21 Jan 2021) mainly developed for robotics and embe ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Install Raspbian on SD Card for Raspberry Pi 3. Today, I am going to start this new tutorial series on Raspberry Pi 3. In this series, we will first cover the basic tutorials for beginners and in the second phase, we will interface raspberry Pi 3 with different sensors and modules etc. In the third phase, we will involve cloud computing and will upload different data over to web server. I will take it step by step from basics to pro. I hope you will enjoy it. You should first have a look at Introduction to Raspberry Pi 3, where I have discussed the basic overview of this board, along with what it is capable of doing. Consider it a zero tutorial o ...
Welcome to the next tutorial in our Raspberry Pi 4 programming tutorial. In the previous tutorial, we learned the basics of using a Raspberry Pi as the basis for an Internet of Things-based weather station. However, this is a continuation of the previous tutorial. In the subsequent session, we will learn how to develop the Python code that will bring our weather station circuit design to life. Before that, let us learn how to measure wind direction and rainfall.
Wind direction
Wind vanes
Despite their name, wind vanes do not indicate a change in wind direction. Since the arrow on most television weather maps goes in the opposite direction, this may come as a surprise at first. To determine the wind's direction, a wind vane uses the force of the wind on a vertical blade, which then spins ...
Hello friends, I hope you all are having fun. Today, I am going to share the 9th tutorial of Section-III in our Raspberry Pi 4 Programming Course. In the previous tutorial, we interfaced an air pressure sensor BMP180 with Raspberry Pi 4. In this tutorial, you'll learn how to interface an MQ-2 gas sensor with a Raspberry Pi 4. Many apartments, residences, and workplaces rely heavily on these gas sensors to detect smoke or gas and alert the appropriate personnel in an emergency. In addition to gas and smoke, this sensor is sensitive to various odorous gases.
Project DescriptionToday, we will interface a gas sensor MQ-2 with Raspberry Pi 4 and will display the values on Raspberry Pi Console Window.
