Report on Arduino

Aim: Basic introduction of Arduino and practicals on blinking LEDs

Introduction :
  • Arduino is an open-source platform based on easy-to-use hardware and software.
  • Arduino board are able to read inputs and turn it into an output.
  • What we have to perform, We have to sending a set of instructions to the micro-controller on the board.
  • You can use the Arduino to read sensors and control things like motors and lights.   
        
  • There are a number of different type of Arduino.
     1.     Arduino Uno
     2.     Arduino NG, Diecimila, and the Duemilanove (Legacy Versions)
     3.     Arduino Mega 2560
     4.     Arduino Mega ADK
     5.     Arduino Yun
     6.     Arduino Nano
     7.     Arduino LilyPad


Use of Arduino :
  •  Arduino is an open-source platform for building electronics projects.
  •  Arduino consists of both a physical programmable circuit board and piece of software or IDE that runs on your computer, used to write and upload computer code to the physical board.

Features of Arduino Uno :

1.     An open source design.
2.     An easy USB interface.
3.     Very convenient power management and built-in voltage regulation.
4.     32 KB of flash memory for storing your code.
5.     And last, but not least, a button to reset the program on the chip.





Pin Description in Arduino Uno :

●      Vin pin is use input voltage to Arduino when using an external power source.
●      5V pin : Regulated power supply used to power micro-controller and other components on the board.
●      3.3V pin : 3.3V supply generated by on board voltage regulator.
●      GND Pin is a ground pin.
●      Reset button is use for reset the micro-controller.
●      A0-A5 pins are analog pins which are used  to provide analog input in the range of 0-5V.
●      0-13 pins are use as input-output pins.
●      Inbuilt LED pin 13 is use as to turn on the inbuilt LED.
●      AREF pin is use to provide reference voltage for input voltage.
●      Maximum current draw is 50mA.
