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.

Purchase the modules from following link.

Circuit diagram is given below.Qa, Qb, Qc and Qd are the inputs to 74LS47 as marked in PCB. Watch the video demonstration of working of “Single digit seven segment display module using 74LS47”.
