The motto of this project is to indicate availability of space in the parking areas of commercial centres etc., A simple example illustrates the use of an up/downcounter for solution.

The Purpose

It solves the confusions in the parking area.Our system will display essential vacancies available forcars in commercial centres.Simple concept of up counting and down counting is used in this project. When a car enters, the entry display is up counted and the exit display is down counted and vice versa when a car leaves.

The Technology

The DPDT switch is supplied with 5V.Two outputs from the switch is given to J and K in the flip flop. Q output is given into pin 5 of first 74190 IC and Q? is given to the second. The BCD output from the counter circuit is decoded using 7447 and fed into seven segment display. The switch control symbolizes entry and exit. Accordingly the output is displayed. When the exit seven segment display displays 0 then the comparator LM358 gives 4 to 5V output (logic 1) which is used to illuminate the LED indicating unavailability of space.

Additional Details

The IC 74190, 74191, 74193 are the counter ICs. The reason for choosing IC 74190 is to give a BCD output. But the other two ICs give binary outputs. IC 74193 has two different pins for up counting and down counting.
