PLC small project problems

Hi everybody. I have taken class in PLC last summer. I diced that I am going to do a small project to understand plc more and how other devices can interfere with the plc

My project detail is :

it is a one level parking lot with 5 parking space ( small scale project)

* 2 inputs ( sensors for entering and exiting)
* 2 outputs ( gate for entering and exiting)
* 1/2 output(s) ( for the display : number of empty spaces and full sign. up/down display)

My problem are : 1. what is a cheap PLC that cover the details ?
2. How I chose display and let it interfere with plc ? (some ideas?)
3. where I can find small gates like the one in the real parking lots( l---- )


Please If you have any ideas let me know
Thanks

Hello,
I don't know about gates, but for a cheap PLC and display look at the click PLC's and c-more micro series HMI from automation direct.
Hope this helps,

Dave

From my standpoint as someone learning PLCs for personal home-automation projects, I strongly agree with Dave's recommendation of the Click.

As for miniature gates, maybe someone makes them for model railroad layouts?

Choose one that will connect to and work with your PLC. Link to a C-More Operator panel that will connect to the CLICK:
