Now Arduino Uno can be implemented in your breadboard. eeeBoxbd.com presents ATmega328P with Arduino Bootloader. With this chip you can make your own arduino with all necessary circuitary.
ATmega328P with Arduino Bootloader: Sometimes you may face such a situation when you need an arduino but you do not need all the digital I/O and analog pins. Also, your project may not have enough space to accomodate an arduino board.
What if you could use the processor of Arduino UNO(I.e ATmega328P) in your project omitting the arduino board?
ATmega328P with Arduino Bootloader is the perfect solution for this. This product is an ATmega328P micrcontroller programmed with Arduino bootloader. So, you can make your own arduino uno by using this chip.
This tutorial shows how you can implement Arduino UNO in your breadboard by using this chip.
1)ATmega328P with Arduino Bootloader-1 NO
2)USB to Serial Converter-1 NO
3)16 MHZ Crystal Oscillator-1-NO
4)22pf Capacitor-2 Nos
5)104 capacitor-1 NO
6)10K Resistor-1 NO
7)1K Resistor-1 NO
9)USB Cable A to B-1 NO
1)Placing the micrcontroller on breadboard: Place the microcontroller on your breadboard and make the connection like the following diagram.
2) Connecting the converter to the microcontroller:Take the USB to serial converter and connect the TX0 pin of the module to the Rx1 pin of the micrcontroller,Rx1 pin of the module to the Tx pin of the microcontroller.

You also have to place a 104 ceramic capacitor between DTR pin of the module and the Reset pin of the microcontroller.
Do Not forget to short the VCC and GND pins of the converter with the VCC and GND pins of the microcontroller.

3) Connecting the converter to the computer: Now connect the USB to serial converter with your computer through an USB cable. The Go to device manager. The following window will appear. The device will be shown in the COM Port.
4) Opening Arduino software:Open the arduino software. Go to Tool—>Board–>Arduino Uno. Go not forget to go to ‘Serial Port’ and select the proper COM Port where the USB to serial converter has been detected. Fot this example this is ‘COM 3’.
5) Coding:Now upload the example code named ‘blink’ and the LED attached to D13 will start to blink. This way you can load any arduino code to the chip and use it just like an arduino omitting the board.
