Perancangan Modul Peraga untuk Praktikum Sistem Digital

Abstract

Practical conditions for assembling ICs and connecting LED cablesbreadboard as well as the difficulty in creating combinational logic circuits at the start of the practicum activities, it was felt that it did not provide a good experience for the practitioners in the Control and Computer Systems Laboratory, Faculty of Engineering, Department of Electrical Engineering, University of North Sumatra. The tools that are capable of practicing digital systems are still limited and the tools offered do not have the ability to combine basic logic gates. Seeing this, researchers created a prototype demonstration module that can solve the problem of limited equipment that occurs in digital systems laboratories. The aim of this research is to create a prototype tool that can work according to the truth table, has low cost and can be used for 22 types of experiments in digital systems practicum. The main components used are 27 ICs with the types of IC used namely TTL and CMOS with a body made of 3mm thick acrylic. In basic logic circuits it is designed so that the results can be seen on the LED lights with values that can be taken so that combinations between basic logic gates are possible and in complex logic circuits the results can be seen directly on the condition of the LED lights. The input values given also adjust the truth table and the results will be observed through the condition of the LED lights and match the conditions in the truth table. This research produces a tool that can work according to the truth table and the tool is able to carry out combination circuits between logic gates.
