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 ...

Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a webserver in raspberry pi. We also looked at configuring addclient and deploying apps to our repositories. This tutorial will teach us to set up a free media server on Raspberry Pi.
Using a Raspberry Pi as a multimedia server requires:
An operating system and miniDLNA program installed on your Raspberry Pi,
You can attach various cleanly formatted and fragmented hard disks to your Raspberry Pi for storing and streaming media files.
A basic understanding of how to use a computer, Client-server architecture skills, familiarity with Unix terminal and Secure shell, and a passion for computing and the media are a must!
Even if you ...
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 ...
Hi friends, today we are going to explore mathematical computations in ladder logic. Like in any programing language you should find logic and mathematic computations, here in PLC programming you often need to process the input data that is collected from reading analog devices like temperature, level, flow et cetera. Then you need to run some calculations on this data to derive some other variables for deciding to run or stop some device or even to determine analog output to output to analog device i.e. valve or actuators. In the following sections, we are going to explore the mathematical functions and their input operators and outputs as well. Then we will show how to utilize such functions in ladder logic with simple examples and as usual enjoy practicing them thanks to the PLC simula ...
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 ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet.
To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers.
Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications.
Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR s ...
Hello friends, I hope you all are doing great. Today, I am going to share the 6th tutorial of Section-III in the Raspberry Pi Programming Course. In our previous tutorial, we have seen how to interface an Ultrasonic Sensor with Raspberry Pi 4 and used Python to perform its calculations. In today's tutorial, we'll discuss how to interface a DHT11 temperature and humidity sensor to a Raspberry Pi. So, let's get started:
ComponentsHere's the list of components, we are going to use in today's circuit:
LCD display
DHT11 sensor
Raspberry pi
Breadboard
Male-to-female jumper wires
What is a DHT11 sensor?
DHT11 is a low-cost digital sensor, used to measure temperature and humidity in the surr ...
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.
