Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4. Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4.
DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits.
Project Description
Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD.Let's have a look at the components required for this project:

Hi Guys! I welcome you on board. In this post today, we’ll study What is Raspberry Pi Pico? We’ll also detail Raspberry Pi Pico Pinout, Specs, Projects & Datasheet.
Raspberry Pi Pico is a little different from other modules introduced by Raspberry Pi Foundation. This unit is similar to Arduino Nano and is called a microcontroller board that incorporates a powerful RP2040 chip. This is different from other single-board computers that fall under the Raspberry Pi series. It is not a computer but a microcontroller board.
I suggest you buckle up as I’ll explain Raspberry Pi Pico in detail.
Let’s get started.
What is Raspberry Pi Pico?
Raspberry Pi Pico is a microcontroller board (released on 21 Jan 2021) mainly developed for robotics and embe ...
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 ...
During the era of Covid-19, social distancing has proven to be an efficient method of reducing the spread of contagious viruses. It is recommended that people avoid close contact as much as possible because of the potential for disease transmission. Many public spaces, including workplaces, banks, bus terminals, train stations, etc., struggle with the issue of keeping a safe distance.
The previous guide covered the steps necessary to connect the PCF8591 ADC/DAC Analog Digital Converter Module to a Raspberry Pi 4. On our Terminal, we saw the results displayed as integers. We dug deeper into the topic, figuring out exactly how the ADC produces its output signals. In this article, however, we will use OpenCV and a Raspberry Pi to create a system that can detect when people are trying to avoi ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Install Raspbian on SD Card for Raspberry Pi 3. Today, I am going to start this new tutorial series on Raspberry Pi 3. In this series, we will first cover the basic tutorials for beginners and in the second phase, we will interface raspberry Pi 3 with different sensors and modules etc. In the third phase, we will involve cloud computing and will upload different data over to web server. I will take it step by step from basics to pro. I hope you will enjoy it. You should first have a look at Introduction to Raspberry Pi 3, where I have discussed the basic overview of this board, along with what it is capable of doing. Consider it a zero tutorial o ...
Greetings, and welcome to today's tutorial. In the last tutorial, we learned how to construct a system for tallying individuals using Raspberry Pi, astute subtraction, and blob tracking. We demonstrated the total number of building entrances and exits. Feature computation and HOG theory were also discussed. The tests proved that a device based on the raspberry pi could effectively function as a people counting station. One of the many benefits of the Pi 4 is its internet connectivity, which is especially useful for home automation projects due to its low price and ease of use. We're going to see if we can use a web page's buttons to manage our air conditioner today. With this Internet of Things (IoT) based home automation, you can command your home gadgets from the comfort of your couch. T ...
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 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. 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 ...
We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. I will show you how to install and connect the RFID card chip to your Raspberry Pi through step-by-step instructions.
Modern security systems would only be complete using radio frequency (RFID) devices. To control who can enter a facility or which rooms they can access, RFID chips and card readers are employed. The RFID card's unique identification number can be read wirelessly with a wall-mounted RFID reader. A door will only unlock and allow entry if the RFID card's unique identification number matches a list of approved cards.
It's fun to tinker with this circuit, and it may be used in many other applications, from opening locks to taking a ...
