hello i have one idea ... i wanna make a NFC/RFID Tarot Reading table but who can help me to tell me how i connect a arduino uno to RFID RC522 and a diplay and SD card ... and how can i make some how a database for cards ... i need to read 10 cards once for every tarot reading ... and when i put the card on the table i want to write on the display what meen the card and the position of the card and to the and making some kind logg for printing or put on the sd/stick for consultant ... i searched a lot codes online everywhere ... i fund something but is not really helpfull ... and i want machine to be started with a smart card or something like this or if i need another kind of arduino i wanna know ... thank you and sorry for my english
the best way to start is to make a list.
you want to use all 78 Tarrot card, so you need to write what each means.
and then what each means in each location. the 4 of Swords will mean one thing in position 3 (goals/destiny) and something completely different in position 4
once you have all 780 meanings, you can store them on an SD card for reference.
then each card would have some way to indicating what position it is in.
not sure if an RFID would be able to know if it was in position 3 or 4 and I think that positions 1 and 2 would require some way to know if it is horizontal or vertical.
At first I thought about bar code, but, if you go around multiple times, the card on the top wold not be read.
to me a physical problem is how to you read up to 7 cards in one pile ?
and for position 1 and 2, which form a cross in the center, that makes it even more difficult to read 14 cards, 7 horizontal, 7 vertical.
But, I think those are your two largest obstacles.
if you, or someone can figure out how to know what cards are in a pile, then you are really only into programming.
I should have said that if you MUST figure out how to know what cards are in one pile, and not in another,
if you cannot figure that out, there is no need to program.

dave what i want to do is to make table nfc or rfid card ... i saw online you can buy nfc playing cards ....personalized so whAt i need is to make table read from some kind patern ... so what i need is only the description of 78 cards what i have allready
what you need to figure out is how to detect what card is on a spot.
i will make a design and i will send you a pictures to understand
