How to burn Arduino bootloader to atmega 328

In this post we will learn, how to burn hex file in avr microcontroller using programmer and burner software.

List of components/software:

1. USBasp programmer
2. Target circuit board having microcontroller (mine have atmega328)
3. Avrdudes (Burner software)

Prerequisites:
USBasp driver installed in your system.
If it is not installed, then read instructions about installation from my previous post.
USBasp driver installation

Default fuse byte for atmega328 is: LFUSE = 0X62 and HFUSE = 0XD9. It might vary
This corresponds to internal rc oscillator

LFUSE = 0XFF and HFUSE = 0XDE
This corresponds to external oscillator having frequency 16 MHz
