' P7 : In1 Control
' P5 : In2 Control
' P3 : In3 Control
'P1 : Control In4
B2 = 10
FOR W2 = 1 TO 512


HIGH 7 ' The first group of sequences activated P7 and P5 .
HIGH 5
LOW 3
LOW 1


PAUSE B2 ' The pause is used to change between each sequence.
' The break finally controls the time it takes a full turn .
LOW 7 ' The second group of sequences activated P5 and P3 .
