Read Multiple ID-12LA with Arduino Leonardo

Hello,

for a project I need to “read in” three ID-12LA RFID reader.

I tried to use the SoftwareSerial-Library but it is not working. If I initialize more than 1 SoftwareSerial-Port the Leonardo stops outputting serial data over the serial monitor.

Does anybody did something similar and have some suggestions for me?

Thanks.

Try using hardware serial and/or a mux :slight_smile:

Thank you. I thought about a mux to. What mux would you suggest?
