Seven Segment Counter Display Circuit
Description
Here is the circuit diagram of a seven
segment counter based on the counter IC CD 4033.This circuit can be used
in conjunction with various circuits where a counter to display the
progress adds some more attraction.
IC NE 555
is wired as an astable multivibrator for triggering the CD 4033.For
each pulse the out put of CD 4033 advances by one count.The output of CD
4033 is displayed by the seven segment LED display LT543.Switch S1 is
used to initiate the counting.Diode D1 prevents the risk of accidental
polarity reversal.
