Posted on: November 13, 2011, 05:21:57 AMPosted by: Frank BurnsInsert Quoteok, it works.....the only thing i done is to connect ARef with +5V.somewhere i read that without a connection to ARefthe Atmega uses a 1.1V Ref.Voltage.Maybe this is why my poti smokes if i use it with 5V.
plz read my post nr. #4.iam on a breadboard where ARef was not connected
