The A/D-C (Analog to Digital Converter) is for converting analog voltages from eg. a sensor into a digital value.
With a 10 bit A/D-C ans a reference voltage of 5V, an analog voltage will be quntitized into steps of roughly 5mV (4.883mV).

If you're after the exact code fror using it, take a look at the software board, Google something like "ATmega16 ADC code", or try this tutorial (http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=56429&highlight=adc).
