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 great. In today's tutorial, we are gonna have a look at How to Setup 7 inch HDMI LCD with Raspberry Pi 3. It's our second tutorial in Raspberry Pi 3 series. In our previous tutorials, first we have seen the basic Introduction to Raspberry Pi 3 and after that in our first tutorial, we have had a look at How to Install Raspbian on SD Card for Raspberry Pi 3.
Now we are ready to Setup 7 inch HDMI LCD with Raspberry Pi3 and then will start our raspbian for the first time on Raspberry Pi 3. We will also connect keyboard and mouse. In simple words, we are developing our own simple computer. So, let's get started with How to Setup 7 inch HDMI LCD with Raspberry Pi3:
How to Setup 7 inch HDMI LCD with Raspberry Pi3 ? ...
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 ...
Thank you for joining us today for our in-depth Raspberry Pi programming tutorial. The previous guide covered the steps necessary to connect a fingerprint scanner to a Raspberry Pi 4. In addition, we developed a python script to complement the sensor's ability to identify fingerprints. Yet, in this guide, we'll discover how to interface a ws2812 RGB to a Raspberry Pi 4.
Bright, colorful lights are the best, and this tutorial shows you how to set up Fully Configurable WS2812B led strips to run on a Pi 4 computer as quickly and flexibly as possible. In that manner, you can have the ambiance of your home reflect your tastes.
In most cases, when people talk about a "WS2812B Strip," they mean a long piece of extensible PCB with a bunch of different RG ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us how to use a raspberry pi as a DNS server. We also looked at the benefit of this DNS server. This tutorial will teach us to set up Raspberry pi as a VPN server.
This is an excellent method for increasing your network security and getting access to your local area network from the world wide web, but setting up your VPN server might be a challenge. Pi VPN uses a guided install to turn your Raspberry into a low-cost, high-performance VPN server.
What is Pi VPN?
It is an OpenVPN server optimized for all Raspberry platforms above pi 2. It allows you to access your home network over the internet safely and securely. Smart devices and your network can ...
Hello friends, I hope you all are doing great. Welcome to the 11th lecture of Section-III in the Raspberry Pi 4 Programming Series. In the previous tutorial, we discussed the interfacing of the Fingerprint sensor with Raspberry Pi 4. Today, we are going to discuss another sensor named the Pulse rate sensor and will interface it with Raspberry Pi 4.The field of healthcare monitoring has long been seen as a potential use
case for IoT i.e. examining the health
instead of regular checkups and local doctors. Using sensors,
your vital signs can be monitored and transmitted in real time, allowing
a physician on the other side or even an AI to analyze the data and
provide an accurate diagnosis. That does seem somewhat futuristic.
However, we are making steady progress in that direction ...
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 ...
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 ...
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 doing well. Today, I am going to share the 5th tutorial of Section-III in our Raspberry Pi Programming Course. In our previous tutorial, we have seen the interfacing of a PIR Sensor with Raspberry Pi 4. In today's tutorial, we will interface an Ultrasonic sensor with Raspberry Pi and will use Python to perform its calculations. So, let's get started:
