A digital indicator system with 7-segment display

Abstract

Abstract This paper presents the design and implementation of a digital system that uses a 7-segment display to indicate the number of drug tablets in a tablet-bottling assembly line. As well as display the number of tablets in a bottle (from 0 – 9), the display can also indicate the name of the vitamin tablet being assembled (Vitamin A, b, C, d, E). This work presents the digital implementation comprising the logic expression, logic circuit and VHDL code for the Vitamin type in the bottle. A digital implementation to display the number of Vitamins in the tablet bottle as well as the Vitamin type with a BBC microbit microcontroller is presented. The application of this work can be extended to give a visual indication of any industrial application that requires indication of the current production stage/phase.
