First … Congratulation for your up coming wedding
About the SoftI2C:
1. At the master Arduino, I still have pin for SoftI2C … but not for hardware I2C
2. At the ‘slave’ I can use hardware I2C, Since the pin is free … and there is no softI2C ‘slave-mode’ library.
I will need 3 slave .. thats why I can’t use SoftSerial
Sincerely
