Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we implemented a speech recognition system using raspberry pi and used it in our game project. We also learned the fundamentals of speech recognition and later built a game that used the user's voice to play. However, this tutorial will integrate a real-time clock with our raspberry pi four and use it to build a digital clock. First, we will learn the fundamentals of the RTC module and how it works, then we will build a digital clock in python3. With the help of a library, we'll demonstrate how to integrate an RTC DS3231 chip with Pi 4 to keep time.
Real-Time Clocks: What Are They?
RTCs are clock units, as the name ...
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 ...
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 ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at LED Blinking using Raspberry Pi 3. It's our first embedded project on Pi 3 and its quite simple. In our previous tutorials on Raspberry Pi 3, we have seen How to install Rasbian on SD Card for Pi 3 and then we have also setup HDMI LCD with Pi 3. So, now our raspberry Pi 3 is ready to program.
In today's tutorial, we will interface a single LED with digital Pin of Raspberry Pi and then we will design a simple code in Python which will turn this LE ON and OFF. It will be quite simple and I will guide you step by step, but if you got into any trouble then ask in comments and I will help you out. So, let's get starteed with LEd Blinking using Raspberry Pi 3 ...
Hello readers, I hope you all are doing great. This is the second tutorial of the Raspberry Pi programming series. In our previous tutorial, we discussed the basic features and hardware architecture of Raspberry Pi Pico.
In this tutorial, we will discuss the various available development environments for programming the Raspberry Pi Pico. Later, in this tutorial, we will also discuss the installation of Visual Studio Code for Pi Pico programming.

RP2040 supports multiple programming languages like C/C++, Circuit python, and MicroPython cross-platform development environments. Raspberry Pi Pico module consists of a built-in UF2 bootloader enabling programs to be loaded by drag and drop and floating point routines are bake ...
Hello friends, I hope you all are doing well. Welcome to the 9th tutorial of our Raspberry Pi programming course. In the last chapter, we generated a PWM signal from our Raspberry Pi to control the brightness of an LED. We also studied different functions used in Python to perform PWM. In this chapter, we'll get a bit advanced with PWM and use it to control the speed and direction of a DC motor with the help of a motor driver IC.
To control the speed & direction of the DC Motor, we will:
Design a Circuit Diagram.Write Python code.
Components RequiredWe will use the following components to control the DC motor speed:
Raspberry Pi 4.DC Motor.Motor driver IC(L293D).Breadboard.
Jumper wires.
Controlling DC Motor speed wi ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain How to Create PWM in Raspberry Pi 3. In our previous tutorial, we have seen How to Create GUI in Raspberry Pi 3, & we have also controlled an LED from the GUI Buttons. So, I am gonna take that project and will add PWM code in it.
So, I would recommend you to first have a look at LED Blinking with Raspberry Pi 3 in which we have designed this simple project and then check How to Create GUI in Raspberry Pi 3, where we have controlled that LED digitally with GUI. But today, we are gonna control the intensity of this LED by creating a PWM Pulse in Raspberry Pi 3. Along with that, we are also gonna have a look at How to use Scale in Raspberry Pi 3. I will add ...
Welcome to today's article on our comprehensive Raspberry Pi 4 programming guide. As we saw in the previous article, the Raspberry Pi 4 may power a single seven-segment display. In addition, we also interfaced a Raspberry Pi with 4 Seven-Segment Display Modules to display the time. However, this guide will show you how to construct a Raspberry Pi 4 crypto miner that uses very little electricity.
Cryptocurrencies have been the subject of widespread conversation for some time now. It's possible to use your computer to create them, and they can be used as currency. Because of this, the Raspberry Pi can also be used for Bitcoin mining. It's also possible to mine other cryptocurrencies. One drawback of mining is that the cost of electricity often excee ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to print from a Raspberry pi. We also discussed some libraries to create a print server in our raspberry pi. We will learn how to take screenshots on Raspberry Pi using a few different methods in this lesson. We will also look at how to take snapshots on our Raspberry Pi using SSH remotely.
Why should you read this article?
This article will assist you when working with projects that require snapshots for documenting your work, sharing, or generating tutorials.
So, let us begin.
Screenshots are said to be the essential items on the internet today. And if you have seen these screenshots in tutorial videos or even used them in regular commu ...
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.
