The pin configuration of the IC7805 is shown in fig-1. By doing so, we had connected the output and ground from IC7805 to our circuit. So to provide 5v we had used the regulator IC7805 and connected it to the 9v battery. SOURCE: As we are designing a digital circuit and we have idea that all digital circuits requires 5v maximum. There are many different ways to design a circuit for counting device but before discussing that we need to understand the components used for its circuit.ġ. The method of originating the gadget, and problems faced are also highlighted in the report. The report on project “Visitors’ Counter” covers the gadget objectives, its uses, the diagram, lay out, design, component, power supplies, etc. The gadget can be used in almost all spheres of life. The counter is, though, a small gadget yet it helps to count the public entered to any of the service delivery center or to a ware house where from supplies are made either in bulk to keep the “enter” and “exit” record.Ī shepherd with larger number of cattle in a herd to drive may use it to keep his cattle counting true and systematic which bring them out for grazing and back from the yard to the barn ()باڑہ. The data collection for assessment of needs, requirements, deliverables lead to better planning and development. The electronic gadgets made the human life comfortable, systematic, more predictable for the future.
