It is very simple if you have some taste in programming. The code for lighting an LED is given below. What am doing is just enabling a particular port of microcontroller. Here it is PORTD. Before you can use a port you need to set the port as an output port. So that you can output data to that port. If you set the DDR (Data Direction Register) of PORT D (ie, DDRD) as 1, then it will act as output. If it is set to 0 it will act as input.

For those who are new to microcontroller, microcontroller is nothing but a mini computer within a chip. It has ram, a processing unit and all those needed for a computer to work. But in a mini scale. You can program your chip with a burner circuit.You need a software like avr studio to compile the program. Then you need a software like SinaProg to put this compiled HEX program to your chip. I use a USBasp ISP as the burner. You can buy that from www.electroncomponents.com.
