http://www.acm.uiuc.edu/sigarch/projects/welcome/, This page has been created to explain the inner workings of this ground-breaking project. The circuit used employs a PIC16F84 microcontroller to control a (now obsolete) SP0256 speech synthesizer IC originally purchased from Radio Shack several years ago. Data for this IC can be found with an Internet search, since it has been used in many projects. The circuit is activated when the door is opened through a simple normally closed momentary switch in series with the power supply.
