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 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: 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 (2^4 = 16 possible values in total, 12 are used: 1 to 12), the 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). E.g. the picture above, 3rd row (seconds): 101001 is 1 * 32 + 0 * 16 + 1 * 8 + 0 * 4 + 0 * 2 + 1 * 1 is (only the '1' bit): 32 + 8 + 1 = 41

for the minutes we do the same: 32 + 1 = 33 and the hours: 8 + 2 = 10

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