Hi,

i'm building a controller for a cdrom motor that has hall sensors.as i knew,the hall sensors produce 1 when a north or south pole is over it,but not for both.but according to the document attached,the hall sensors give the sequence:

0 0 1
0 0 0
1 0 0
1 1 0
1 1 1
0 1 1
but the hall sensor is giving output for north and south at many instants,even though in the magnet alternate north and south are present.
how is this working?

thank you.

 

????
