This is the third tutorial in our Raspberry Pi programming course. In the previous chapter, we learned how to install Raspbian on our Raspberry Pi mini-computer. In this chapter, we'll learn how to use a VNC server to remotely control and see its desktop from our computer.
What is VNC?
Computing over a network is known as "virtual network computing," or "VNC." To remotely control another computer, you can use this screen-sharing technology, which works on all major operating systems. As a result, a remote user can interact with a computer's display (screen, keyboard, and mouse) as if they were sitting right in front of it.
VNC takes advantage of the client/server concept. Rather than installing a VNC s ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hello friends, I hope you all are having fun. Welcome to the 10th tutorial of our Raspberry Pi programming course. In the last chapter,
PWM was utilized to regulate the DC motor's speed and direction
with a motor driver L293D. In this chapter, we'll advance our skills with PWM and use it to control a stepper motor using the same motor driver L293D.Here's the video demonstration of this project:Let's get started:
Components RequiredHere's the list of components, which we will use to control the speed and direction of Raspberry Pi 4:
Raspberry Pi 4.Stepper Motor.
Motor Driver IC(L293D).
Jumper wires.
9V Battery.
Breadboard.
The Raspberry Pi with desktop is required for this project. An SSH connection can be made, or the RPi can ...
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 Folks! I welcome you on board. Today, I am sharing the 2nd
tutorial in the Raspberry Pi 4 learning series. In this post today,
we’ll cover What is Raspberry Pi 4?
Raspberry Pi 4 Pinout, Specs, Projects, Datasheet etc.
Raspberry
Pi 4 is a tiny dual-display single-board computer, developed by
Raspberry Pi Foundation. This foundation has introduced a series of
Raspberry Pi boards to teach computer basics in schools.
With Raspberry Pi 4, you can control two monitors at once. Moreover, it
is incorporated with a quad-core processor that is powerful and comes
with more speed compared to its predecessors.
I suggest you read this post till the end as I’ll cover Raspberry Pi 4
in detail.
Let’s get started.

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 ...
Welcome back to another Python tutorial for the Raspberry Pi 4! The previous tutorial showed us how to construct a Raspberry Pi-powered cell phone with a microphone and speaker for making and receiving calls and reading text messages (SMS). To make our Raspberry Pi 4 into a fully functional smartphone, we built software in Python. As we monitored text and phone calls being sent and received between the raspberry pi and our mobile phone, we experienced no technical difficulties. But in this tutorial, you'll learn how to hook up the PCF8591 ADC/DAC module to a Raspberry Pi 4.
Since most sensors only output their data in analog values, converting them to binary values that a microcontroller can understand is a crucial part of any integrated electroni ...
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 ...
Following up on our Raspberry Pi programming course is the next lesson. In the previous post, we learned how to construct an FM radio using a Raspberry Pi. Analog FM broadcasting's circuit construction was also studied in detail. How to use a Raspberry Pi as an internet speed meter and save the data in Grafana or Google Drive is the subject of this article.
You can use this article if you want to keep track of how your downloads, uploads, and ping speeds change over time, and it's easy to use. In addition, you can use this to determine when your internet is at its busiest or if your internet speed has deteriorated. We'll demonstrate how to use Ookla's Internet speed test command-line interface in conjunction with Python code to create an internet speed meter.

Hello everyone, I hope you all are doing great. In today's article, I am going to show you How to Control Raspberry Pi 3 from Laptop or Computer. In our previous tutorial, we have seen How to setup 7 inch HDMI LCD with Raspberry Pi 3 and you must have noticed that designing your code on TFT LCD is quite difficult. So, either you have the LCD or not, its always better to work on your Laptop.
In order to control our raspberry Pi 3 from Laptop, we have to use VNC server & client. It's a third party tool designed by RealVNC. We have to install VNC server on the raspberry Pi and VNC viewer on our laptop & after that we can quite easily control our VNC Server from VNC Viewer (Client). So, let's get started with How to Control Raspberry Pi 3 from ...
