## How it works
binary means that every digit can represent 2 states: 0 or 1, displayed by a black bar.
The principle is the same linke in out daily used decimal system with values from 0 to 9:
Binary means that every digit can represent 2 states: 0 or 1, displayed by a black bar.
We start from the right with the least significant bit (binary digit) which can have the value 0 or 1
The 2nd bit from the right can have the value 0 or 2 (sum of all bits to the right set to 1).
The principle is the same like in out well known and daily used decimal system with values from 0 to 9:
We start from the most right position with the least significant bit (binary digit) which can have the value 0 or 1
The 2nd bit from the right can have the value 0 or 2 (sum of all bits to the right set to 1 plus 1).
This principle is valid for all the remaining bits.
Mathematically spoken: the value of a digit is the base number of the system (10 for decimal or 2 for binary)
to the power of the position (from the right, starting with 0).
that means in numbers: 32 - 16 - 8 - 4 - 2 - 1
that means in numbers: 2^5 = 32, 2^4 = 16, 2^3 = 8, 2^2 = 4, 2^1 = 2, 2^0 = 1
The upper row represents the hours with 4 bit (16 possible values in total, 12 are used: 1 to 12)
2nd row represents the minutes with 6 bit (64 possible values in total, 60 are used: 0 to 59).
The upper row represents the hours with 4 bit (2^4 = 16 possible values in total, 12 are used: 1 to 12)
2nd row represents the minutes with 6 bit (2^6 = 64 possible values in total, 60 are used: 0 to 59).
Same holds for the thrid row: 0-59 seconds
To read the values of a row we summ up the vaules of set bits (black bars).

So the time is 10:33:41 (that's all)
