Introduction
Welcome to the next tutorial in our raspberry pi programming. In the previous tutorial, we learned how we could run Xbox cloud on our pi 4. We found that we can run any game easily without lag or having raspberry pi shut down, proving that pi 4 is quite a powerful minicomputer. However, this tutorial will demonstrate how to use Python on raspberry to monitor websites. This Python program will execute on Pi 4 and watch over a website, alerting you whenever it changes or goes down. This is accomplished by keeping a straightforward webpage duplicate locally and monitoring for updates. This webpage monitor is straightforward, so it should work well on pi Zero. Throughout this tutorial, we will demonstrate how to develop your custom code to monitor a webpage. With this information ...
Hello friends, I hope you all are doing great. Today, I am going to share the 6th lecture in the Raspberry Pi 4 Programming series. We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. In today's guide, I'll show you how to interface a 16x2 LCD screen with Raspberry Pi 4.
So, let's get started:Interface LCD 16x2 with Raspberry Pi 4Today, we are going to interface a 16x2 LCD screen with Raspberry Pi 4. At first, we will print the "Hello World" text on the LCD, and in the last section, we will implement the scrolling and blinking of text on the LCD.Here's the video tutorial on LCD interfacing with Raspberry Pi 4:Components RequiredWe will need the following components for today's project:Raspberry Pi 4.M ...
Greetings! This is the complete project of our Raspberry Pi 4 tutorials. In our previous tutorial, we learned to set up our raspberry pi as a virtual private network server. In this tutorial, we will design a smart attendance system using an RFID card reader, which we will use to sign in students in attendance in a class.
First, we will design a database for our website, then we will design the RFID circuit for scanning the student cards and displaying present students on the webpage, and finally, we will design the website that we will use to display the attendees of a class.
Components
RFID card kit
Breadboard
Jumper wires
Raspberry pi 4
I2C LCD screen

Additionally, the Database server offers a DBMS ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to configure our raspberry pi for voice control. We also discussed some methods of reducing vexing noises so that the voice command program understands you. However, in this lesson, we will learn how to tweet from Raspberry pi.
What will we learn?
Assume you wish to add tweeting into a Raspberry Pi software you're developing. This article will show you how to build a Twitter app, get access privilege tokens, and post a tweet. On our Raspberry Pi, we'll make a simple program that tweets the result of the uptime command. This is a made-up example, but it demonstrates what is needed to tweet from a raspberry pi.
For this session, a repo has been set up. Because we'll be referring to code wit ...
Hello friends, I hope you all are doing great. Today, we are going to start a new section in our Raspberry Pi Programming Course. In this section-VIII, we will implement advance protocols in the RPi4 board. Today's our first lecture in this section and we are going to interface a USB Bar Code Scanner with Raspberry Pi 4.If you have visited any big grocery store, you must have seen, it's
quite important as well as difficult to maintain the products in stock
at all times. To ease the job, barcode technology is used because it can
easily maintain an organized database of your items, costs, and
inventory levels in one convenient location. Price changes can be
implemented whenever you desire without requiring new labels for
previously packaged goods. You can tell exactly when your s ...
Hello friends, I hope you all are doing well. Welcome to the next tutorial of our Raspberry Pi 4 programming course. In the previous lecture, we interfaced LCD 16x2 with Raspberry Pi 4. Today, we will interface a keypad 4x4 to Raspberry Pi 4. In embedded projects, a keypad is used to get user input i.e. calculator, ATM keypad etc. Different types of Keypads are available i.e. 4x4, 4x3 etc.
So, let's get started:
Components Required
We will need the following components in our today's project:Raspberry Pi 4Keypad 4x4BreadboardConnecting Wires
Keypad 4x4
A keypad is a collection of push buttons, arranged in a matrix form.Keypad 4x3 means the keypad has 4 rows and 3 columns and 12 buttons in total. A 4 by 4 keypad membrane has 8 pins in t ...
Welcome to the next tutorial of our raspberry pi four programming course. Before, we saw how to connect a Raspberry Pi 4 to a relay with four independent channels. To complement the relay circuit, we programmed a python script to turn on and off a single bulb. However, in this tutorial, we'll show you how to connect a GPS module to a Raspberry Pi 4.
Raspberry Pi 4, one of the most popular embedded platforms, has made it simple for developers to obtain location data via a GPS module, allowing them to create devices with a greater reliance on precise positioning. Because of the Raspberry Pi's impressive processing capabilities, this essay focuses on the exciting prospect of creating GPS-based projects using the same inexpensive GPS chips.
Since thi ...
Hello friends, I hope you all are going great. Today, I am going to share the 10th tutorial of Section-III in our Raspberry Pi Programming Course. In our previous tutorial, we interfaced a Gas Sensor MQ-2 with Raspberry Pi 4. Today, we will be interfacing a Fingerprint Sensor with Raspberry Pi today.
After appearing only in science fiction films until recently, fingerprint sensors are often employed to confirm an individual's identity in various contexts. Today, fingerprint-based systems are used for everything from checking in at the office to verifying an employee's identity at the bank, withdrawing cash from an ATM, and proving one's identity at a government agency. For identifying purposes, fingerprint-detecting technology has been used for so ...
The Internet of Things (IoT) philosophy may be viewed as a highly dynamic and radically dispersed networked system comprised of a huge number of identifiable smart devices. These objects may communicate and interact with one another, as well as with end-users and other network entities. As the Internet of Things era begins, the usage of small, inexpensive, and flexible computer hardware that allows end-user programming becomes more prevalent. The Raspberry Pi, a fully configurable and programmable tiny computer board, is one of them discussed in this article. Although there are certain limitations, the Raspberry Pi remains a low-cost computer that has been used effectively in a wide range of IoT vision research applications despite its few shortcomings.
