Το πρωτο που παρηγγειλα , επειδη νομισα οτι το εκαψα , το εκανα accelerometer.
Στο δευτερο ομως καταλαβα οτι δεν ηταν καμμενο αλλα αλλου ηταν το προβλημα μιας και τα προγραμματα που εβρισκα στο internet δεν δουλευαν με το φτηνο nunchuck που ειχα στα χερια μου παροτι μολις το συνεδεα με την παιχνιδομηχανη δουλευε κανονικα.
Τεσπα για να μην σας ζαλιζω .... οριστε ο κωδικας που κανει το φτηνο μου nunchuck να δουλευει.

Φυσικα ο κωδικας ΔΕΝ ΕΙΝΑΙ ΔΙΚΟΣ ΜΟΥ αλλα με βοηθησε ο crimony στο http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1264805255/0#5
Ελπιζω - πιστευω οτι θα σας φανει χρησιμο.
