3. Motivation
Counting manually is boring and monotonous!

4. Objectives
 To implement a counter that can count up to 10,000.
 To automate current system of counting.

5. Introduction
 This project focuses on building an effective counter using
IR as a sensing element and and will be capable of counting
from 0 to 9999.
 This circuit is designed using CMOS lCs, with
advantages like:
o Very low power consumption.
o Wide supply voltage range
o Good noise immunity
o High package density
o High fan-out capability

10. Circuit
Counter circuit

11. Applications
 Industries- record of amount of products
 Parking areas
 Seminar halls
 Vigilant analytics human counter
 Home automation system
 banks and offices - money counter machines

12. Problems Faced
 One of the major problem faced was because of
floating pins which have different impact on software
and hardware.
 Due to usage of number of wires, noise effects the
output to extent.
 Understanding the concepts of negative and positive
logic circuits.

13. Future scope
 In real time, by using advanced sensors the distance
between receiver and transmitter can be increased and
can be useful to count heavy objects.
 Using different sensors and technologies, we not only
can increment the count of objects but can also
decrement of no of objects going out.
