Making an electronic Monopoly

Hello world !

Everybody know what the "Monopoly" is, don't you ? Well, I have an Arduino (4 standards), an RFID reader (serial) and some RFID cards. I want to turn the old-school board game into a sci-fi like board Game. Actually, what I want to do is simple, I want to use my RFID system as a payment system for each player, and I want to put a tri-color LED in front of each property to tell if it's free or for which player.

The simpliest way to target a place will be (at the beginning) through a numeric pad, 2 digits: the first one will be the side where the place is, the second digit will be the number of the place on the previously given side. Then, if i still have courage, I will put a button near every LED, to allow players to directely choose a place by pushing the button instead of using the 2 digits rule.

Actually, my question is: Is there a LED strap, or something that contains at least 36 LEDs (the small squares) and which allow me to control each LED one by one (on/off/colors) ? If not, any advice on how I could proceed ?

Thank you for your help.

You could try something like this: ("addressable led strip" on google) http://www.sparkfun.com/products/10312

Getting the pitch to match your board might be tricky, but it would probably be worth it -- they're slim, don't take many pins, and make construction take a lot less time.

I'd suggest putting a hall effect sensor under each square, and have one piece have a magnet north pole down and the other south pole down. Then you could detect where each one was. Then maybe combine that with player1 and player2 "buy" button that automatically subtracts the correct amount. I'm guessing the hardest part would be mortgaging and upgrading, though -- you'd have to embed a button in each deed card! Or get enough rfid cards (like http://www.sparkfun.com/products/10169 ) and have a reader (the "bank") with a "upgrade" "downgrade" and "mortgage" button on it.

Thank you, but unfortunately it's 32 LEDs, do you know where I can get a 36 one, or 4x9 or 4x18 (to match the squares) LEDs that I can plug in serial to avoid making the strip turn at each corner ?

I think it would be easier to use, isn't it ?

Sorry, can you explain me this a little more? If I understand, you mean I should use a U magnet, with each pole at the same side, but how to make the difference between 2 or more pieces ?

For me, it's the easiest part. I was thinking about adding an LCD screen and a keypad to enter the amounts (for an exchange) and to select a menu (buy, exchange...), and I will use the RFID cards only to identify and confirm a transaction.

Thank you for your help.

Isn't that what Apple has? :stuck_out_tongue_closed_eyes:

It depends on what you're talking about. I was talking about the board game :) Isn't it the same name in US ?

I thought it was pretty funny.

Yes, the game has the same name here.

Well you don't have to get that one exactly; you'll need to do a little research to find one that's the correct pitch and length. I'm just showing you that that kind of product exists and gave you an example.

Not a U magnet; something like this: http://www.kjmagnetics.com/proddetail.asp?prod=D51-N52 There you can just glue it onto the bottom of each piece. On those, one flat side is north and the other is south. The right kind of hall effect sensor would tell you if it sees a north pole, a south pole, or no pole.
