Simple summary, I want to add something to my corn hole set that keeps track of what back is on the board (1 of 2 teams) and which one goes through the hole. Ignoring any that might not make it on the board.
I was looking at inductive coils around the outside of the board and to put something inside of each bag with an identifier to each time. However, I couldn't find much on making a unique identifier with that scenario.
Then I was looking at RFID but couldn't find any material on if something was inside of an area, only that it would sense something in a general range, which would not be accurate enough.
Does anyone have any ideas?
