on these outputs the actuating signals are used to enable the different status signal.

The display section also consists of certain status signals. The different status signals include:

1. A yellow signal to indicate that a car is currently in the process of entering or leaving the parking space.

2. A green signal to indicate that the parking lot has not reached its maximum capacity and that space is available for the parking of a car in the parking area.

3. A red signal to indicate that the parking space is full. The activation of this signal coincides with the disabling of the g..................[:=> Show Contents <=:]

ble. The clock out pin of the IC1 is connected to the clock pin of IC2 in IC1 except clock pin all other pins are kept low but in IC2 except clock pin and A2 pin all other pins are low. It helps the counter to count 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 r..................[:=> Show Contents <=:]
