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 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 ...
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 ...
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.

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.
If you've been tinkering with a raspberry pi for a while, consider the various ways ...
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 ...
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.

Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to make a button-controlled "music box" that plays different sounds depending on which buttons are pressed. In this lesson, we will configure our raspberry pi for voice control.
What will you learn?
Like the Amazon Echo, voice-activated gadgets are becoming increasingly popular, but you can also construct your own with a Raspberry, a cheap USB mic, and some appropriate software. Simply speaking to your Raspberry Pi will allow you to search YouTube, view websites, activate applications, and even answer inquiries.
What will you need?
Because the Raspberry Pi lacks a soundcard or audio port, this project requires a USB microphone or a camera with a ...
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 ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of pulse width modulation (PWM) in Raspberry Pi Pico using the MicroPyton programming example. We also implemented the LED brightness control program to demonstrate an application of the pulse width modulation technique.
In this tutorial, we are going to implement another application of pulse width modulation technique which is ‘Direction and position control of a servo motor’ with Raspberry Pi Pico module and MicroPython programming language.
Later in this tutorial, we will also discuss how to control the position of a servo motor with push buttons (to be used as control inputs) and also to use LEDs for indication purposes.
What is Servo Motor?
Before interfacing the servo motor with ...
