Well Thomas, thanks for your clear and fast respond.
Pse tell me what type usb to serial port cable I have to buy. I search but get
confuse as many type was provided.
I can buy from the local suppplier at around USD 29 w/ present IDR currency.

Hi,
The chip used by the Arduino Uno, and used by Farhan in the minima is the
Atmega 328P-PU.
For reference, the original datasheet is here:
http://www.atmel.com/Images/Atmel-8271-8-bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA-168A-168PA-328-328P_datasheet_Summary.pdf
The -PU means it comes in a DIP package.
To program this chip with the Arduino tools and the serial port you need to
have the bootloader programmed on it. What I meant is that you can buy the
chip with the bootloader already on it, or just program it yourself.
The bootloader that is recommended now is the Arduino Optiboot bootloader:
https://code.google.com/p/optiboot/
Pre-programmed Atmega328 with bootloader like this:
http://www.ebay.com/itm/4x-Atmega328-w-Arduino-UNO-Optiboot-Bootloader-ATMEGA328P-PU-4pcs-/380827609802?pt=LH_DefaultDomain_0&hash=item58ab182aca
or
http://www.ebay.com/itm/ATMEGA328P-PU-with-UNO-Bootloader-Arduino-Genuine-ATMEL-/321254166986?pt=LH_DefaultDomain_0&hash=item4acc3d91ca
Or not pre-programmed (== without the bootloader):
http://www.ebay.com/itm/1-x-ATMEGA328P-PU-ATMEGA328-MICROCONTROLLER-IC-FREE-SHIPPING-/321044251247?pt=LH_DefaultDomain_0&hash=item4abfba826f
Hope this helps.
cheers,
thomas
