  So this DIY Weather Station involves a few different Hardware modules and a little bit of programming. The idea is, to display the weather status, temperature and humidity levels on a LCD Display that gets updated on a hourly basis. Our Raspberry pi W is going to host the programs and is responsible for sending the correct data from the internet to the Arduino Nano over a Serial communication. We'll make use of the bluetooth module to connect to the bluetooth capabilities of pi to send the data over to the display unit. Things required : Raspberry Pi Zero W x 1 Arduino Nano x 1 LCD 1602 Display x 1 I2C module x 1 Bluetooth HC-05 module x 1 Jumper wires for making connections 5V power source for both raspberry pi and arduino nano (we can power other modules from nano board) Setup Arduino Nano Our LCD Display Module can be connected to Arduino nano in two ways, with or without I2C module. Without it, we'll need to connect 8 pins to the Arduino which is tedious and time consumin

The blog post is divided into two sections, in first we will explore creating a basic server for our application. This server uses basic web scraping techniques to retrieve data from a trusted news portal. We are only scraping article title and article link, but can expand feature to include more data as well. In the next section, we will create an a cross-platform app from scratch for both iOS and Android. This app is going to retrieve the data from the server we created in Section 1 and display to the user. Section 1 Building a server : npm install --save express request-promise cheerio Add these dependencies to a new file newsAPI.js. const express = require("express"); const app = express(); const rp = require("request-promise"); const $ = require("cheerio"); app.use(express.json()); app.get("/", (req, res) => {   res.send("Hello !!!"); }); const port = process.env.PORT || 3000; app.listen(port, () => console.log(`http://localh

 All Vianet users are aware that Youtube doesn't work in NetTV STB box provided by Vianet. The box is basically an Android OS 6.0 flashed with NetTV image, which means if you can access Play Store you should be able to install Youtube Android app and use it normally. Also, the method described here doesn't impact your regular nettv usage since you can go back to watching TV channels anytime. Items required : USB Keyboard and/or USB Mouse Google account (the one in your android phone if available) NetTV STB box setup connected to a TV display Steps : Unplug your ethernet cable. You'll instead connect to WiFi. Plug in your keyboard to the box and make sure it is turned on. Navigate to Settings and then Network. Select Wireless and connect to your home wifi as you would connect on a smartphone. Go back to home screen and on your Keyboard, press Windows Key( Win ) + B . This will open android browser. Navigate to  https://play.google.com/store/apps  and login using your google

Ever since github opened private repository feature to general user, all the developers have been moving their project repo to github. I myself too jumped on the bandwagon recently, and started putting up old projects as well as unfinished ones(there's a lot of those) as private repos in github. I had been taking shelter under gitlab and bitbucket as a backup place for them, but decided it was time to move them to github once and for all. Steps : 1. First I pulled the projects off of the old repo, using the following line :     git clone <git-project-url from old repo> 2. After getting inside the project directory, I used the following command to point it to my newly created repo in github.     git remote set-url origin <git-project-url from github> 3. I entered the following to confirm the change worked.     git remote -v Now, if you didn't have a README.md file on the previous repo, but github created one for you when you created the repo, this is going to create

This sounds like what a lot of beginner developers need right now. You make an app and you want it to be available to users instantly without having to distribute using pesky installation files or google drive links. Also, when you start out on Expo, you hear a lot of 'cross-platform' keywords being thrown around, and that's what brought you to Expo in the first place. Now that you're ready to start sharing, you need help publishing it to the stores and making it instantly ready, so you can focus on other things such as marketing, testing, feature upgrade and so on. This guide attempts to piece together what you'd need to for publishing your app to both android and ios store. And yes, you don't necessarily need a MacOS hardware for publishing to iOS App store. Once you're ready with making all changes, you're ready to build the production version. Pre-requisites Firstly, update the version code in your app.json file. This is done so that each time you up
