0b00000010 works, it's standard C++ (binary)
Along with 0x02 (hex)
Or just 2 (decimal)
Get away from using B00000010, that only works from B00000000 up to B11111111 because there is some Arduino code that defines
B00000001 = 0x01;
or
B00000001 = 0b00000001;
or
B00000001 = 1;
or similar in one of the files
