So today we are going to make a weather station which is powered by An Arduino nano.Which can monitor the live temperature and humidity of the climate? And also print the data on an LCD display.By this project, you can easily understand the working of the DHT 11 sensor and LCD display. So to make this project you need this component:- Arduino board (any types of) LCD 16X2. DHT 11 module Connecting Wire Breadboard(optional) What is DHT 11 MODULE? DHT 11 or 22 are the digital humidity and temperature sensing module for Arduino, avr, raspberry pi.Adafruit industries basically made this sensor.This module is the low-cost humidity and temperature sensor which has only one pin to transfer the data. So it required a careful timing to grab the data sent by it. But its very simple to use/interface with any kind of projects. We basically need the libraries to use it properly.It speaks the data after 2 sec. The cost of this kind of sensors is near about 3-4 $. But DHT 22 is m

So today I will tell you how to use the 16x2 LCD display on the Arduino projects. If you are doing any kind of projects then you should interact with the user in the simplest process.To add any kind of output device is the key to simplify that project. you may show the options or the compilation details using that.  There various types of displays available in the market but among them the 16x2 LCD display is the famous and cheapest one.As it has a very simple process to implement them in the projects. pinout for the 16x2 LCD display: circuit diagram for 16x2 LCD display: Test code to check the connection is properly done or not: /*   LiquidCrystal Library - Test code   #DNY  Demonstrates the use a 16x2 LCD display.  The LiquidCrystal  library works with all LCD displays that are compatible with the  Hitachi HD44780 driver. There are many of them out there, and you  can usually tell them by the 16-pin interface.   The circuit:  * LCD RS pin to

SO we all know about Arduino. That is basically a programmer board or you can say it is a prototype board where you use that to make a prototype of your hardware. Arduino is open source platform and you can find the internal circuit or ide any whare for free. So to make an Arduino is very easy at home. if you go for the original Arduino Uno then it cost you around 23 to 24 $ . and the chipper variant or the Chinese one costs you around 10 $. So to make an Arduino is very useful, and by going through the process you get more familiar with the architecture and function of the Arduino. components:- ATmega microcontroller 8/128/328  16/12 MHz crystal. 22pf bypass capacitor. 100-ohm resistance. female or mail header pins as per your requirement.  zero PCB. connecting wire.  soldering kit. USB ASP For programme the controller. Procedure:- cool down your mind and heat up the soldering iron. play a decent song and start soldering the circuit board properly as per the dia

WHAT IS WIFI:- It may happen that now you are connected to a wifi router and surfing the internet through that.But did you know how the data is displaying in your computer or phone's display? when your device is not connected with any of physical connecting wire. The wifi is basically an electromagnetic radiation, just like the microwave, visible light or the gamma rays but the only difference is the use, the frequency and wives length of that radiation. Wifi signals basically use the two bands 2.4 or 5 GHz. And it basically transmits the data in the form of 0 and 1. The wifi signal uses the same concept of a radio F.M but this communication is two way. HOW IT REALLY WORKS:- The wifi networks basically break the data in small encrypted packets and send back and forward between your router and portable device. The packets also have the address of the destination node and the decryption key. And after the data is received by your device through wifi network, your device ha

What is SSH? SSH stands for secure shell.  It is a networking protocol which is used to secure the data flowing between the SSH client and the servers over a public network such as the Internet. WORKING:- When a client tries to connect to its SSH server its needs to be verified. To establish a secure connection between them. In this protocol, this verification is completed using the exchange of cryptographic keys. And after when the client and the server are successfully connected, the process of transmission of data takes place.  But the data in an encrypted form. So as a result, a secure tunnel like security system is formed. In general, the port 22 is used for this SSH connection. USES:- SSH is famous among the network administrators. Because it helps them to manage their systems and applications remotely, allows them to log in to another system or computers over a public network, execute commands and move files from one device to another.
