ll as down counts if configured for the same. The count is incremented by one when a rising edge is encountered on the up pin (pin 5) and decremented by one when a rising edge is encountered on the down pin (pin 4) of the circuit, the former occurs when the vehicle has entered the parking area and the line Y0 clears the output of the final flip-flop, causing a transition from the high to low logic state, which when passed through an inverter, provides a rising edge. The count decrements in the same fashion as the flip-flops in question are those used for detecting the vehicles leaving the park..................[:=> Show Contents <=:]

from 20 onwards. Here we are implementing a down counter which counts from 20. When 20 peoples had entered the theater the count reach 0 and the counting stops. When the count is stopped the door is closed until the show is completed. If the show is finished the door is made open for people to left from the theatre.
The output from both the counter is given to the two driver ICs respectively there are only four outputs from the counter ICs from driver ICs these output is passed to the seven segments through seven pins the seven segments consist of ten pins. By this the display works efficien..................[:=> Show Contents <=:]
