Communication
Library used to connect OPTA and OPTA Expansion Modules on I2C / UART
This library discover the presence of different Expansions (for example OPTA Digital) present on the I2C bus, automatically assing addresses to them and allow to control their Input/Output from the Opta Controller.
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
