In all cases of programming the "hello world" program is always a good 
start.
On Microcontrollers I would devide this in three steps:
HelloWorld_A would be a blinking Led, controlled by an Port Pin
HelloWorld_B would be a microcontroller connected to uart transceiver 
(Maxim232 et al.) to a PC
HelloWorld_C would be a interrupt controlled Led blinker (e.g. Timer 
interrupt, or PWM)

But datasheet reading should not be considered boring, the interesting 
parts will blink in your eyes :) and the "boring" parts will be reminded 
by you for later reading.

Especially if you want to use AVRs to do your work, AVRFREAKS.COM is a 
great place to start, and some other forums, too (like 
http://www.mikrocontroller.net for starters)
