Design And Development Of Large 4-Digit Seven-Segment Driver Circuit

A 7-segment display is commonly used in electronic display device for decimal numbers from 0-9. There are many experiments relative to 7-segment display including making enlarged seven-segment display. The problem in operating a functional and programmable large seven-segment display using a breadboard and with development connected is that the breadboard allows less flexibility in routing a group of components in the recommended way and loose connection can possibly encounter. The objective of this study is to develop a driver circuit for large 4-digit seven- segment display to prevent the user to take too much time on troubleshooting for a probable cause of loose connection. The product was tested by performing a queuing sample experiment. In this experiment, the performance of the product will be checked on how the buttons and large seven segment display interacts with the developed code. Buttons were able to properly execute as what was programmed to them and the enlarged digit seven-segment display clearly shows the result Thus, the researchers were able to develop a functional large 4-digit seven-segment display driver circuit without the development board. In the future, this driver circuit can be innovated so that it can cascade to another driver circuit and control more large seven-segment display.
