I do not know how to convert a number to binary. I have seen the way with Serial.print(x,bin) but what I want is a variable to take the binary and not just to print it. For example : When x is a random number y = (x, BIN);

How to convert a number to binary ?

Yes I know. Serial.print(y,bin).

Close, but no cigar.
