number of cars that can be parked after last entrance (16-1 = 15). Each car that comes
out will automatically be added to number of slots available in the garage. When 16
cars are parked, a signal (red LED indicator) will turn on and off, indicting that the
garage is full and notifying other drivers not to enter because there is no space avail-
able. A two digit numerical Seven Segment LED Display (installed at the parking en-
trance) shows total number of vacancies.

2. The total number of available slots in the garage is updated when a car is either enter-
ing or exiting the parking lot. There is a Break-Beam sensor at the entrance of the
garage which sends a signal to the microcontroller anytime light beam between trans-
mitter and receiver is broken (IR sensor shown in
Figure 1.3
). If there is any vacant
space for the incoming car to park, Entrance arm gate is lifted to let the car to get in.
Otherwise, the red LED light blinks with higher frequency to warn the driver that no
space is available to park.
