I'm trying to play music based on which RFID card is over the reader. Everything is working properly, the cards are being recognized, and I can get the music to play if it's not within the if statement.
When I put the card with tag 1600a8c21c over the reader, it is recognized and prints the card tag, but the if statement does not execute.
I would have assumed that tag == songTag when the card is over the reader, but for some reason this is not the case. The relevant if statement is at the very bottom.
Thanks for any help
