Having an issue with the RTC and really confused on how its behaving like this...
I have a piezo sensor being used as vibration knock sensor. On a Proto1 Shield using A1 pad. I have tested this alone with the core board + usb shield and everything works fine.
Moving on, core board + usb shield + rtc shield. flash it, set time, call time and works as expected.
Now, looking at the spec section here it seems that RTC uses A4 and A5. But when I put the 2 shields together and go back to testing the piezo, i'm getting a fixed voltage 1 second pulsed signal on A1. Very odd. If i knock on the piezo it disturbs the voltage. but still is pulsing.
So serial monitor looks like this (using AnalogRead simple code)
0
0
0
0
788
788

0

ect
Have already tried A0 as well as is doing the same thing. Looks like the two aren't playing nicely together and i cant figure out why. RTC is super simple and uses A4/A5 so should be separate from everything else correct?
Any help greatly appreciated!
