Digital Answering Machine using Microcontroller AVR AT90LS8535

Project description:
We decided that an answering machine was interesting because it involved interfacing many analog parts, a reasonable amount of coding, and would leave us with a finished product that actually does something. The answering machine is one of few everyday microcontroller utilities that can be implemented fairly easily and we are really happy with our final product. We also realize that we share a common fear of analog circuitry and felt this would force us to gain working knowledge of this material.
