Making your own arduino...!!!

Hiiiii...
   Now we are going build a arduino board..before knowing this WHAT IS ARDUINO..??? it a combination of some hardware (say microcontroller)along with compatible software(ARDUINO Ide)
Above pic shows the basic ARDUINO board with atmega328p as its heart.so,now in this post I will tell u how to make your own board.for doing this you should require
Atmega328p ic with base
16 MHZ crystal oscillator
22pf capacitors
7805
Male headers etc....
 If you buy a atmega328p,initially it is not ARDUINO Ide compatible microcontroller. So to make it a ARDUINO compatible mc you must burnboot loader to that ic..it's very easy and simple procedure for that process is explained below
 To burn bootloder u must have an ARDUINO board and breadboard with required components. ARDUINO to breadboard connections is shown in below pic


Burning the Bootloader

If you have a new ATmega328 (or ATmega168), you'll need to burn the bootloader onto it. You can do this using an Arduino board as an in-system program (ISP). If the microcontroller already has the bootloader on it (e.g. because you took it out of an Arduino board or ordered an already-bootloaded ATmega), you can skip this section.
To burn the bootloader, follow these steps:
  1. Upload the ArduinoISP sketch onto your Arduino board. (You'll need to select the board and serial port from the Tools menu that correspond to your board.)
  2. Wire up the Arduino board and microcontroller as shown in the diagram to the right.
  3. Select "Arduino Duemilanove or Nano w/ ATmega328" from the Tools > Board menu. (Or "ATmega328 on a breadboard (8 MHz internal clock)" if using the minimal configuration described below.)
  4. Run Tools > Burn Bootloader > w/ Arduino as ISP.
You should only need to burn the bootloader once. After you've done so, you can remove the jumper wires connected to pins 10, 11, 12, and 13 of the Arduino board.
After completing the above process now our task is build the board
Solder all components by following above circuit.. Use ftdi chip to program ur new ARDUINO..or other wise u can use your ARDUINO board as programmer...
