Hi heliflyer,
Have you had any luck?.One thing to try is to put a jumper between the centre and outside pin of where the pot connects
and check the raw data, it should be 255 and stable when the link is between the centre and the 5v pin, and 0 when connected
to the other pin. Also make sure you havnt got long unshielded leads connected. A pic of your setup may help us.
Let us know how you go.
