Looking to have an interactive skeleton, where kids can place bones in spots to try to correctly assemble the animal.
RFID buttons on the bottom "plug" of each part, location lights up LED if part is in correct hole on the board (10 to chose from).
To cut down on cost I'd like to only have one RFID reader, with the Arduino cycling through a mux to read a single antenna at a time to see if the correct RFID tag is at that location.
I'm looking at the ID-3LA RFID reader (uses external antenna 125Khz) and using 4 ADG904 antenna switches as the mux (3 to cover the 10 spots, one to mux between those 3).
Does this sound feasible? I'm not well versed in RF sensitivities.
