Description. The circuit shown here is of a simple 0 to 9 display that can be employed in a lot of applications. The circuit is based on asynchronous decade counter 7490(IC2), a 7 segment display (D1), and a seven segment decoder/driver IC 7446 (IC1). The seven segment display consists of 7 LEDs labelled ‘a’ through ‘g’. By forward biasing different LEDs, we can display the digits 0 through 9. Seven segment displays are of two types, common cathode and...

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. In this circuit a 7-segment display is connected with two NE555 IC’s and CD4033 IC to display counts from 0 to 9. The IC CD40333 is a 5 stage Johnson decade counter with decoder and...
