I am trying to design a puzzle where something opens when it detects several correct objects placed in their respective correct spots. I am thinking about having up to 8 separate spots that need to be filled with the correct object.
If object 1 in correct spot and if object 2 in correct spot.. .. and if object 8 is in correct spot do a certain output
The only way that I have thought of to be able to do this so far is to have multiple RFID antennae connected through a multiplexer. However, after reading through the other RFID Multiplexer questions it seems like there are voltage issues when you try to string multiple antennae together.
Does anyone on this forum have any suggestions for achieving this?
