  Smart Weather Station(using Arduino) A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. So today we are going to make a working prototype of it which helps us to find the temperature and dew. This project works on the principle of Bluetooth master and slave modes. Come on let’s get started Step 1: Things Required Arduino x 2 HC-05 Bluetooth Module x 2 16x2 LCD Display x 1 DHT 11 x 1 Breadboard x 2 Communication Cable Step 2: What Is the Bluetooth Master and Slave Mode? Bluetooth networks (commonly referred to as piconets) use a master/slave model to control when and where devices can send data. In this model, a single master device can be connected to up to seven different slave devices. Any slave devi

 Home Automation Using Google Firebase Introduction : This is a home automation project which uses firebase and nodeMCU. First why I have chosen Firebase is because it can be maintained easily it has progress report, Crash Analytics etc and exactly it is free of cost so we can use this project to control the lights, fans, TV, etc. So let's get started Supplies: NodeMcu - 1 Nos  Relay Module - 1 Nos  Breadboard - 1 Nos  Male to female jumpers – 3 Nos An internet connection An android phone Step 1: Creating Database First you need to go to  this website  and log in to your Google account.       And click on create a new project    And give your project name and click continue. After a few minutes, it says, “your project is ready “and a continue button appears to click it, the dashboard appears. On the left side database tab will be there click on it.   And slowly scroll down you will see create real-time database button click on it.   It opens a dialog box telling you to choose eithe
