Four-channel lighting sequences

With four light circuits, it is possible to display 16 different combinations (24 =16). In computers, that would take half of a byte (known as a nybble). These 16 digits are given the numbers 0-F in hexadecimal notation, as indicated below.

All 16 possible patterns (0-F)
