The case study below consists of controlling a parking using Part$1-$ Microprocessor $8085$ and its peripherals, Part$2-$ Microcontroller and its peripherals.

This parking has $1$ entry and $1$ exit gates; at the entry gate we have installed a metallic barrier connected to a DC motor and $2$ Laser sensors to detect the front $($LsF$\_$In$)$ and the end $($LsB$\_$In$)$ of a car to allow entry. In the exit gate, we installed ONLY $2$ Laser sensors to detect the front $($LsF$\_$Out$)$ and the end $($LsB$\_$Out$)$ of a car. The parking capacity is $($CarN$=255)$ cars and should be controlled according to the RFID of the users and Laser sensors$.$

The RFID board is producing a $1$ if it is programmed for right users $($already programmed$)$ and $0$ for the wrong persons.

The digital system is working according to the following

$-$Part $1$: write the code for $8085$ microprocessor and its peripherals

$-$Part $2$: write the code for microcontroller PIC$16$F$84$A and its peripherals
