Here are some of the programs demonstrating the features of the AVR microcontrollers. The ordering is mostly according to increasing difficulty.

It would be better if you keep the AVR Datasheet open and have a look at the various registers used in the programs. The "Register Summary" on page 334 of this datasheet would be helpful to find the Register's detailed page.

If you have any doubts, feel free to contact me.
