INTRODUCTION TO IOT AND EMBEDDED SYSTEMS

-
                                         INTERNET OF THINGS 
                                    AND
                     EMBEDDED SYSTEMS

 MAINLY OUR TOPIC CAN WHOLLY BE DIVIDED INTO TWO PARTS.1st PART IS THE EMBEDDED SYSTEMS AND THE SECOND ONE IS ABOUT THE INTERNET OF THINGS.

 1.Embedded means something that is attached to another thing. An embedded system can be thought of as a computer hardware system having software embedded in it. An embedded system can be an independent system or it can be a part of a large system.Embedded processors can be broken into two broad categories. Ordinary microprocessors (μP) use separate integrated circuits for memory and peripherals. Microcontrollers (μC) have on-chip peripherals, thus reducing power consumption, size and cost.
 (i)microcontroller only controls the flow of signal. eg. arduino,nodemcu
 (ii)microprocessor at first decodes the signal and the encodes the signal in its own term.
     eg. raspberry pi
2.Internet of things basically means connecting the several embedded systems with the server or cloud.Basically it can connect a lot of embedded systems with the server and can exchange their responses.One can sit in office and can automate his home from there.Several devices available in the market like arduino, nodemcu which provide the basic need for several introductory iot projects.
Arduino Uno R3
NODEMCU(having inbuilt wifi module esp8266)

NOW IN THIS POST I AM GOING TO DISCUSS ABOUT A BASIC PROGRAM OF BLINKING   A LED USING ARDUINO                                                                   We will complete the project in two part hardware part and programming part. (i) Hardware part; -for the hardware part the things that are needed are                                     (a)arduino board                                     (b)breadboard                                     (c)resistor and led                   ...

Building a Wifi controlled bot using Nodemcu and l293d motor driver ic

For this project we need a l293d motor driver ic, a breadboard, some jumper cables,nodemcu(esp8266),a five volt power supply(or i can just use arduino for the 5v power supply as that 5v is not present on nodemcu),a 9v supply to run the motor.                                                                               L293D                                                               CHASIS FOR THE BOT                                                              NODEMCU(ESP8266)...

Bascis of Arduino and its description.

                            .          ARDUINO    It is a microcontroller which can control both analog and digital signal according the program uploaded in it. The boards are equipped with  sets of digital and analog  input/output  (I/O) pins that may be interfaced to various expansion boards or  breadboards.Basically you could send your desired signal to the desired location.We can connect several input devices like sensors,touchpad,keypad etc. with other input devices like display,speaker,motors,led etc. Several types of arduino are available in the market like:- (i)Arduino UNO R3 (ii)Arduino lilypad (iii)Arduino Mega (iv)Arduino Robot (v)Arduino UNO R2 etc. Discussing about Arduino UNO R3 , It is a microconroller .It has 14 digital pins(0-13) followed by a GND(ground) and 6 analog pins(A0-A5) followed by two GND and one 5V and one 3.3V and Vin.
