This is the first tutorial with AVR where we will get hands on! Let's do a 'hello world' for Embedded. We will interface a simple LED with one of the port pins. The LED as might know emits light when current is passed through it. It could blow up if we pass more current ( >20mA depending on make and type), hence we put a current limiting resistor. Usually 220, 470 and 1K ohm resistors are found. You can use any of these, it should not be an issue. Well instead of a single one, we can as-well connect a bunch of these to port and blink them.

Hookup

You may look this up with the simple breadboard as shown in section below or you could use the Ultra AVR dev kit if do not wish to jumble with wires and resistors.
