O-9 counter using IC 4026

MAKERS: Arundev COUNTRY: India

In our normal practical life, we may face circumstances where we need a digital event counter in order to count certain events.

The Purpose

people counter circuit in an auditorium, to count the number of products in a godown, to calculate an athlete?s performance and above all, all the digital clocks are basically counter circuits which generates an one second clock. Here we are providing similar kind of counter circuit diagram.

The Technology

In this led 7 segment display counter circuit we are using a single digital counter IC (4026) both as counter and 7 segment driver. A common cathode 7 segment display is used here. The IC used here requires only clock pulses for operation. By increasing the number of ICs and seven segment displays you can extend the counting limit up to infinity. This can also be made into a digital frequency counter circuit.
