Dear All..
I'm trying to connect two Arduinos to the same computer, and both have six RFID readers connected to them. I'm trying to build a videogame using Unity that uses the data sent through the serial port coming from the RFID and I managed to do it with one Arduino Uno.
The problem is I need to use two boards at the same time and I don't know if it's best to buy another board or extend the pins on the one board i have with many MCP23S17 expanders.
Thank you.
Best regards, Nicolò
