RFID Reader

Right now My project partner and I are trying to create a program where if we bring a certain card up to the reader it will read the entire code and make a decision at the end of the byte and tell us what it is and what number we installed it to remember. At the moment we have created a program that can show the memorization of the cards for a certain number, but can't turn off the LED DIGIT counter. Can you come up with a program that can incoporate all of this?

    Heck yeah, we can!

    More importantly, can YOU?

    You'll need to describe what you want more thoroughly, post your code thus far, and identify what it's not doing for any useful help.

    Where in the code do you have a problem? How do you have things connected to the stamp (what pins go where)? What are you expecting and what are you getting instead?

    The problem is in the program code where i can't make certain i.d tags to come up with the numbers i want and then turn off and got into a loop where i can do it again. I have the Digit LED counter connect from pin 15 down to pin 8 and my RFID reader is connect to pin 0 and 1. What i was expecting to come out was to write in a seperate sub category in the program code and have the I.D card showned and have it display a certain number and then create a loop where it goes through all that process again. What i get is that it makes it decision every byte it goes through instead of going through it all then making a decision. If you can make a program that can do all this please post it.

    Thank you Sam. I am not adept at programming, however, and am not quite sure how to tweak your program so that it meets my needs. What do I do to my code so that, when an RFID card is detected, a seven segment led displays that tag's given number? I am close, but it seems as though my programming is slightly off. Right now, I am trying to get the system to be capable of detecting five rfid tags and consequently displaying their respective numbers on the led display.
