- Purpose: The entry/Exit of the parking lot is a single lane passage. By controlling the indicators, the program ensures that only one car can pass through the Entry/Exit so as to prevent car accident between entering and leaving cars. Y1 X1 Program Description: In the parking lot, there are two light indicators individually directing the entering and leaving cars. By the interlock control circuit, only one indicator will show "GO" signal and the car accident will thus be prevented. When an the same time, the leaving car indicator will show "STOP". Car entering is allowed but leaving is prohibited in this case. When a leaving car draws near the vehicle control barrier, X1 will be ON and so will Y1. The leaving car indicator will show "GO" and the entering car indicator will show "STOP"| draws near the vehicle control barrier, XO will be ON and so will YO. The entering car indicator will show "GO". At TOP GOarrow_forwardA microcontroller of PIC16F84A and a 7-segment LED are used to form an down- count counter from 9 to 0.
