Single digit seven segment display module using 74LS47 IC

Single digit seven segment display module using 74LS47 IC

Introduction

7-Segment displays are always interesting to electronic beginners. Various methods are there to interface 7-segment displays in circuits. 7-Segment displays are of two types.

  • Common anode 7-segment display
  • Common cathode 7-segment display

74LS47 is a BCD to 7-segment decoder/driver which can be used to interface common anode 7-segment displays in circuits. Here, we will see a module using 74LS47 by which we can make a 0-9 counter in few simple steps.
