Today we are going to discuss about arduino
Many tutorials are already available in many websites in english
i am going to explain the same in malayalam
Arduino is simply a development board for atmega
we can program the ic and make awesome circuits
i purchased this board online
it is available in most of all online markets like "ebay" "amazon" etc.
many arduino compatible versions are also available
this is original MADE IN ITALY arduino board
it will be marked at the back side of the board
also the reset button will be near the usb port
in clone boards it will be near the controller
arduino having hardware as well as software parts
you can download the software from the link below
as i said, arduino has a controller called ATMEGA 328
we can program it and make circuits as u wish
for that there is a USB SOCKET which can be connected to PC via cable
there is an optional powersupply socket
we can draw less than 500ma from Usb
so we can use the optional power socket for additional power if needed
the maximum input voltage is 20v
there are 14 digital pins in this board
naming from 0 to 13
the six analog pins (ADC pins) naming from A0 to A5
we can input analog signals here
we can input or output digital signals here
here is a reset button to reset the controller
among these digital pins, six pins can also be used for Pulse Width Modulation
digital pins 0 and 1 can be used for serial communication
serial communication can be visualised via two led provided TX and RX
this is the power supply section
the optional input power is available in the "VIN" pin here
two ground points are there
the input voltage is regulated to 5v using this voltage regulator & available at the  "5v" pin
there is a 3.3v pin which is from usb to serial converter ic within the board
this can be used as power supply for  3.3 level modules
the maximum working frequency of atmega328 is 20Mhz
the working frequency of arduino is 16 Mhz
the main hardware parts of arduino are almost covered here
now we will se how to interface the board to your comuter
to interface your board to your system, u need a usb A-B converter cable
one end is Usb-A type and other is Usb-B type
The B-type side will be compatibe with arduino and A-type for Computer
i have already connected one end to computer
i am connecting the other to Arduino
here the power LED is glows ,indicates the power-up of the board
now letz see how to interface  drivers on computer
firstly, download Arduino software from the link provided--or see this
www.arduino.cc is the official website
go to DOWNLOADS
all the versions; older as well as the latest version is available here
setup for different platforms are also available . Download the version you want.
here i am downloading latest version for windows :)
this is the downloaded file, just doubleclick it
choose the directory where u want to install
installation compleated
I had connected the Arduino
now we can check wether it is detected on the computer
rightclick in MY COMPUTER--> Go to MANAGE
click DEVICE MANAGER on the left
it shows the details of all the devices that are connected to the computer
Arduino will detect here as a serial port
lets check the communication port(COM PORT)
as we already installed the software, it will install drivers automatically
it detected as arduino UNO (COM 3)here
if driver is not installed automatically, it will seen as unknown device
rightclick that device--> UPDATE DRIVER Software
brouse the location in which where we installed arduino software
select the "drivers" folder in it
do not forget to include subfolders
this will install the suitable driver for arduino
here the communication port of our ardiono is COM 3
open the application shortcut of the arduino software from the desktop
this is the programming interface of arduino
here we can write our programs, compile it , convert to HEX file and upload it to arduino
In the next videos we will see how to connect hardware, how to write programs ,how to test itand much more
So stay tuned to this channel you can post your comments about the video
