Abstract

A microcontroller-based instrument has been built into an old telephone handset. The instrument provides keypad input and multi-digit display output. The keypad in the telephone handset is used as the input device, and a raster generated on standard oscilloscope is used to produce a display showing a multiple-digit output. This device has been used as a standard interface for many different digital systems designed by students in the second quarter digital circuit design class at the University of Minnesota Duluth.
