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 ...
Abstract: This paper is written to represent a web-server based real-time weather monitoring system implemented using the ESP32 module. The system is designed to measure the weather conditions like temperature, pressure, humidity etc, in its vicinity. This system continuously provides real-time data (weather conditions) over limited or controlled areas, for example, agriculture fields, homes or a particular room, industries etc. Although we have satellites for weather monitoring but to perform research over a particular area, the data observed should be highly accurate which is not possible with satellites. To implement an IoT network we need to use a webserver to continuously store and display the real-time data which can be accessed globally. ’T ...
Hello readers, I hope you all are enjoying our Raspberry Pi Pico programming series. In our previous tutorials, we learned how to access Raspberry Pi Pico’s GPIO pins for both input as well as output operations. For demonstration, we used LED as an output component and a push button as an input component.
Now let’s learn how to interface sensor modules with the Raspberry Pi Pico module. So, in this tutorial, we will learn how to interface the DHT11 sensor with the Raspberry Pi Pico module and fetch the observed data (from its surrounding) using the MicroPython programming language.
Before writing the code for interfacing and fetching the data from the respective sensor, let’s first have a look at the working operation, features and properties of the DHT sensor.

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 ...
Hello geeks, welcome to our new project. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well.
So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages.
Software to install
We will make this project in the simulation, as it is a good practice to make any project in the simulation fir ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the installation procedure of Visual Studio Code for programming Raspberry Pi Pico.
We have already mentioned in our previous tutorials that RP2040 or Raspberry Pi Pico supports multiple programming languages like C/C++, Circuit python, 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 baked into the chip to achieve ultra-fast performance.
There are multiple development environments to program a Raspberry Pi Pico board like Visual Studio Code, Thonny Python IDE, Arduino IDE etc.
So, in this tutorial, we will learn how t ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...

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:
