                                    What is ZigBee or XBEE?           Zigbee   or Xbee is a communication protocol used for a suite of high-level communication specially built for control and sensor application on IEEE 804.15.4  .It uses  Media access control(MAC) and physical layers to operate different devices at low data rate.  it is used to set up wireless personal area networks (WPAN) . It connects one device with other wirelessly. Basically it is used for remote control and sensor applications.    Basic Concept of ZigBee or XBEE        Zigbee or XBEE transmits signals from one station to the next station extend up to about 10-100 meters, although more greater distances can be reached by broadcast data from one node to the next node in a network.  One Zigbee networ...

  Artificial intelligence is the intelligence displayed by the machines while making choices on their own unlike natural intelligence possessed by the humans and animals.  It is all about designing and building such machines that could make decision by using previous data or feedback to make decisions.  Alan Turing, the father of computer science, first set the fundamentals and the visions of Artificial intelligence with a simple Question:    I propose to consider the question, 'Can machines think?  Basically AI (Artificial Intelligence) is branch of computer science that aims to answer the Alan Turing's question by enabling the machines to take decision at their own.  It is an initiative to stimulate or replicate the human intelligence in the machines. AI makes it possible for the machines learn from the past data or experiences and feedback system to make decisions. 

                    Simple Calculator in Python     We are going to write code for a simple calculator in python, It will show you that how can you use basic python statements and function to make a calculator that will do addition, subtraction,multiplication and division. Calculator python coding: def add (a , b): return a + b def subtract (a , b): return a - b def multiply (a , b): return a * b def divide (a , b): return a / b print ( "Select Desired Operation." ) print ( "1.Add" ) print ( "2.Subtract" ) print ( "3.Multiply" ) print ( "4.Divide" ) while True : choice = input ( "Enter choice(1/2/3/4): " ) if choice in ( '1' , '2' , '3' , '4' ): num1 = float ( input ( "Enter first number: " )) num2 = float ( input ( "Enter second number: " )) if choice == '1' : print (num1 , "+" , num2 , "=...

                             Python Basics What is VARIABLES in Python? As the name implies the meaning, a variable is something which can be change. A variable is a way of referring to a memory location used by a computer program. A variable is a symbolic name for this physical location. This memory location contains values, like numbers,text or more complicated types. Variables can be treated as a container which can store some value in it. In any other languages for example C++, This is how you write a variable int a = 20 Where int is data type of the variable. Int stands for integer. String refers to text or collection of characters. It is represented in single quotes or double quotes. Float refers to decimal point numbers. In Programming languages like C++ you have to specify the data type of a variable. But in python you don’t have to worry about data type. Whatever value  you give the variable, python...
