Development of devices that assist students with incorrect wiring detection in combinational logic circuits

Abstract

In experiments, students are training design and assembl y combinational logic circuits . These circuits use for decode BCD (Binary Code Decimal) to 7 segment LED display. Since this assembling requires a lot of wiring, there is a high possibility that connections will be mistaken. It is difficult for students to repair circuits , because they can’t detect the incorrect wiring. The purpose of this study was to develo p device s that assist students with incorrect wiring detection.
