car parking system using PIC16F84A

hello,this is my first time joining this forum.i have doing my fyp on car parking system using pic.i having the difficulties by doing the coding and joining the circuit.my coding is not correct and my circuit is unable to stimulate.can anybody help me in this problem? or anybody have knows any blog or anybody that have doing this car parking system project? i really appreciate you all help.

Post your schematic.

sorry..i'm didn't know how to insert my schematics diagram in this forum.can anybody help me?

actually, I'm thinking of doing a project that works like this same like parking lot system:
At the entrance of a parking lot, a LCD display will notified driver the availability of parking space at each level or zone. A sensor will be located at each entrance and exit to count the number of cars entering and leving that level or zone ( a car entering will increses the count and car leaving will decreases the count).
Can anyone help me with the circuit design for this project? Info on the hardware and programming neded for this kind of project is also appreciated. my project is using the PIC16F84A and MPLAB IDE.. thanks.

hi eyan,
When replying, use the 'Go Advanced' button, then the 'Manage Attachments' button,,, use the pop up window to find the file on your PC, select it and the 'Upload' it.
When done, post it.

this is my schematics using multisim.but i didn't find the compatible sensors or component for sense the vacancy parking lot yet. can anyone help me?

hi,
The xtal is incorrectly wired.
The wire ends of the crystal go to the PIC pins and a low value cap is from each xtal pin to 0v.

thanks. i will try to fix it. can i use sensor encoder for this car parking system? or do you have any suggestion about the sensors for this system?
all your advise i will appreciate. thanks again.

hi,
If you use the Forum SEARCH button the menu at the top of the page, type in Car Parking, there is a lot of information.
