hello fellow arduinoids.
i have a arduino Uno, and a ladyada SD Shield with a Realtime clock on it that communicates on the pins A4,A5.
but now i changed the code using the Software realtime clock and am logging it without using the pins A4,5. the question is how do i stop the communication on the pins A4, A5? so that i can use them as analog inputs.?
secondly i removed all the code about wire.h and the rtc 1307, including the void loop and in the void setup(). but still after uploading i get 5.06V on the pins A4, and A5.
any help would be greatly appreciated.
