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 lack some of the expertise mentioned above and experi ...
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 workplaces where employees may print from any busine ...
In the past, graphic designers had limited choice of graphic design tools. There were only 3-5 great design tools for professional work. This has all changed with free and open-source platforms making it easy to design what you want, wherever you want it. Also, many of these tools are cross-platform too, meaning you can whip up some quick designs on your Android or iOS device. Because the sheer number of available tools makes it harder to pick the best one, we are going to look at 5 great ones that you should be using right now. Adobe Illustrator Almost all designers agree that Adobe Illustrator is the best tool for creating vector graphics . You can use the software to create artwork, logos, infographics, artwork, icons, and pretty much anything else you like. Adobe Illustrator uses mathe ...
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 server on the distant device, users will instead use a VNC viewer or client on the device ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention. Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32. We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to access Firebase (a real-time database) to store and read values or data with ESP32. It is Google’s mobile application development platform that can be used to can access, monitor and control ESP32 from anywhere in the world with its (firebase) real-time database. What is Firebase? Firebase real-time database is a development platform provided by Google which included multiple services to manage and authenticate data. Firebase is basically a mobile and web app development platform I as works great with Android APIs) that includes features like firebase cloud, real-time data and Firebase authentication etc. As per Firebase’s official documentation ( https://firebase.google.com/docs/database ), whenever a us ...
Selling an app to a buyer requires a careful approach to extract the most value from the digital asset. The marketplace for apps extends well beyond the iOS and Android market to ones for e-commerce platforms, Amazon’s Alexa, Salesforce, and many other places. If you’re thinking ahead about the long-term prospect of selling your app that’s now in development or wanting to exit in the next year, these 5 tips for selling an app are for you. Can You Sell The App? You might believe it is time to cash out your app, but there could be a few problems in your immediate future. Apps developed for the Apple ecosystem can’t always be transferred from one developer to another. It is a good idea to check the latest criteria on app transfers before you look at selling your app. While developers can tran ...
Everyone is talking about Flutter, and if you are looking for Flutter developers for hire, you’ll know how competitive and difficult the recruitment process has become.

Hello! Readers, I hope you are pretty good. I am here with a new article to enhance your knowledge about advanced technologies. Today, we will have a detailed overview of the Manufacturing Process of Multilayer PCB . First, we will have a look at its basic definition, why there Is a need for this new type of PCB in presence of single layer and double layer PCBs. What are the merits and demerits of multilayer PCBs and pedagogy behind the construction process of these PCBs? Let’s start to take in all information about these PCBs. I try my best to deliver all of my research capacity for doing this job. Introduction to Multi-layer PCBs As to the name, it's clear that multi-layer PCBs are those which have several conductive layers over substantial material which is knowns as substrate. Unlike s ...
Hello readers, I hope you all are having fun in your lives. Welcome to the 2nd Chapter of Section-2 in the ESP32 Programming Series. In today's lesson, we'll go over another built-in feature of the esp32 module that helps it stand out from the competition: BLE or Bluetooth Low Energy. In the previous tutorial, we discussed the Classic Bluetooth in ESP32 , which is considered the predecessor of Bluetooth Low Energy(which we are going to discuss today). We will first look at, what is BLE? and why is it used?, and then will design some examples to utilize the ESP32 BLE in Arduino IDE. What is BLE? There have been numerous adjustments and upgrades to Bluetooth's characteristics since its inception, where Bluetooth 4.0(also called BLE or Bluetooth Smart) is the most influential. BLE or Bluetoot ...
