Serial output from the firmware.
Create options in using different variable values with #define statement. The advantage of this method is that the same codebase can be used for different options.
Run command make a to put the LOCAL_ADDRESS value as 0xAA.
Run make b to put the LOCAL_ADDRESS value as 0xBB.
The make command will run the arduino-cli compile with options to #define the LOCAL_ADDRESS and DESTINATION_ADDRESS values.
